Explanation:
Annual precipitation amounts in centimeters are shown in the table for four environments. Which environment experiences the least humidity? (2 points)
Environment A 80–120 cm
Environment B 20–50 cm
Environment C 150–200 cm
Environment D 40–60 cm
The environment that experiences the least humidity is Environment C 150–200 cm. The correct option is C.
What is humidity?Humidity is the presence of water vapor in the atmosphere. If the water vapor in the atmosphere is high, then the high is humidity, when the vapor in the atmosphere is low, it is called low humidity.
Precipitation is the presence of condensation in the atmosphere. It creates hail, snow, or haze. It happened due to the gravitational pull of the clouds.
Here, the humidity is given 150–200 cm. of the environment C. The higher the precipitation, the lower will be the humidity. When the rain is high, there will be more humidity due to water in the atmosphere. So, Annual precipitation will be higher.
Thus, the correct option is C. Environment C 150–200 cm.

Animal Reproduction Interactivity
Can you describe how an aquarium moon jellyfish population will change over time?
Record Data and Observations
Part 1 Explore the Life Cycle
For each transition in the jellyfish life cycle, indicate whether it is the result of growth, sexual reproduction, or asexual reproduction. Provide the evidence that supports your choice for each.
Adult medusas to larvae
Larva to polyp
Polyp to reproducing polyp
Reproducing polyp to juvenile medusas
Juvenile medusas to adult medusas
Analyze and Conclude
1. Draw Conclusions Once polyps have been established and are producing juvenile medusas, is sexual reproduction required to provide adult medusas for the exhibit? Explain why or why not.
2. Scientific Writing The museum has asked you to make a sign for the exhibit. Visitors will read the sign when guides and volunteers are not available to talk about the exhibit. Using the information gathered in this interactivity, write a paragraph that describes what visitors may see in the tank and explains the reproductive cycle of jellyfish.
Step 1
Jellyfish do not give birth to their young because they expel undeveloped eggs in the form of zygote or embryo from their bodies and deposit them on the ocean floor before moving on. They don't even care about the eggs that have been laid.
Step 2
Jellyfish have two distinct body types during their lives: medusa and polyps. Polyps reproduce by budding while medusa reproduce as by spawning eggs and sperm.
Jellyfish can reproduce in the adult, or medusa, stage by releasing sperm and eggs into the water, forming a planula. Polyps clone themselves and bud, or strobilate, into ephyra, a different stage of jellyfish life. The adult medusa jellyfish develops from his form.
Only a few jellyfish species obtain sperm through their mouths in order to fertilise eggs within their bodies, but the majority of jellyfish simply release sperm or eggs into the water. They will do this once a day, normally at dawn or dusk, if conditions are favorable.

A.The population size is increasing
B.The population size is decreasing
C.The population size is remaining the same.
D.The population size cannot be inferred from the graph
Answer:
A. The population size is increasing
Explanation:
Looking at the graph upon the x-axis we see the blue line at an increasing direction to the right. That means the population is increasing at the 1 year mark.
In an ecosystem , where there are no predators which can prey upon coyotes and they have plentiful food their population size is expected to increase which can be inferred from the given graph.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

When a population grows past the ecosystems carrying capacity, what happens to the population?
A.Continues to grow
B. The population starts to die off
C.The population grows then finds a new carrying capacity
Answer:
the Answer is B
Explanation:
If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size. Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species.

Answer the following questions with a pictures.
1. What is the main source of energy for ecosystems?
2. What are some natural things that can disturb ecosystems?
Write a paragraph (5-8 complete sentences) using the prompt below in purple:
An ecosystem has many living and nonliving things. Choose one producer, one consumer, and one decomposer. Explain how they work together.
An ecosystem is made up of all the living and nonliving things in an area. The living parts include plants, animals and insects. The nonliving parts include water, rocks, soil and sand. Swamps,prairies, oceans and forests are all examples of ecosystems.There are usually many different kinds of life in a single ecosystem. A grassland ecosystem, for example, contains much more than just grass. It includes other plants, mammals, insects and earthworms. It also includes many tiny living things in the soil.Three Roles For Living Things Each living thing in an ecosystem has a role to play. The three main roles are producer, consumer and decomposer. Green plants are producers. They make their own food through a process called photosynthesis. Animals, including humans, are consumers. They eat, or consume, plants or other animals. By Encyclopaedia Britannica,
Bacteria and other living things that cause decay are decomposers. Decomposers break down the waste products and dead tissue of plants and animals. They return nutrients to the soil. These nutrients help new plants grow. Producers, consumers and decomposers depend on one another and provide nutrients for one another.This is called a food chain.Feeding Levels A food chain describes the order in which matter and energy move through the feeding levels of an ecosystem. The levels of a food chain are basically the same across all ecosystems. The first level is the producers. After that is the consumers. Sometimes consumers are further divided into primary consumers, secondary consumers and tertiary consumers. The final link in all food chains is the decomposers. The decomposers break down dead organisms and natural waste.The consumers at the top feeding level of a food chain are called top predators. They have no predators hunting and trying to eat them. Instead, their population size is controlled through competition. They have to compete with one another for food and other resources.Energy FlowThe main source of energy in almost all ecosystems is the sun's energy. As energy moves through the ecosystem, much of it is lost at each feeding level. Itescapes as heat. That is the main reason why few food chains have more than five feeding levels. Diagrams called energy pyramids are used to show the flow of energy from one feeding level to the next in a food chain. Most ecosystems have more than one food chain. Food chains overlap. They connect to form a food web.Recycling Nutrients Many nutrients are constantly cycling through an ecosystem. These include water, carbon and nitrogen. A nutrient is something that helps living things grow.Nutrients from soil enter into plant tissues. When consumers eat the plants, the nutrients enter the consumers' tissues. Consumers that are eaten transfer the nutrients on to the predator at the next feeding level. Consumers that are not eaten die and transfer nutrients in their decaying tissues to the decomposers that feed on them. The decomposers recycle these nutrients back into the ecosystem. They transfer the nutrients back into the soil and air, where the nutrients become available to producers.A Delicate Balance
an ecosystem's health depends on a delicate balance. This balance must exist between all of the members of the ecosystem, and their surrounding environment. If something disturbs the balance,the ecosystem and all its members might suffer. Natural things that can disturb ecosystems include a changing climate and natural disasters.Human activities that can disturb ecosystems include polluting and clearing land for farms or buildings.Humans also are responsible for many invasive species. An invasive species is a living thing that spreads through an ecosystem where it did not exist before. Invasive species can threaten the plants and animals that originally made up the ecosystem. For example, Burmese pythons were brought to Florida as pets. Some pythons escaped and began reproducing in the wild. Their skill at hunting has decreased the number of wood rats and storks in the area. This upset the balance of the natural ecosystem.

1.Which description matches the histogram of the population 50 generations ago?
A.Most of the newts had low-poison level traits; very few had high-poison level traits.
B.Most of the newts had high-poison level traits; very few had low-poison level traits.
C.All of the individuals in the population had high-poison-level traits.
D.None of the individuals in the population had high-poison level traits.
2.
Which description matches the histogram of the population today?
A.Most of the newts have low-poison level traits; very few have high-poison level traits.
B.Most of the newts have high-poison level traits; very few have low-poison level traits.
C.All of the individuals in the population have high-poison level traits
D.None of the individuals in the population have high-poison level traits
Answer:
B for the first answer
Explanation:
The histogram of the population 50 generations ago showed that the majority of newts had low-poison level traits and very few had high-poison level traits. Now, the histogram of the population shows that the majority of newts have high-poison level traits and very few have low-poison level traits. So, the correct option for 1 and 2 are A and B.
What is Histogram?A histogram is a graphic depiction of a frequency distribution with continuous classes that has been grouped. A series of rectangles with bases equal to the distances between class boundaries and areas proportional to frequencies in the associated classes make up the area diagram.
Since the base in such representations spans the spaces between class boundaries, every rectangle is neighboring. For above given example, The population's histogram from 50 generations ago revealed that most newts possessed low-poison level features, while just a small number possessed high-poison level traits. Now, the population's histogram reveals that most newts exhibit features associated with high poison levels, whereas relatively few exhibit traits associated with low poison levels.
So, the correct option for 1 and 2 are A and B.
