Explanation:
What are two types of secondary succession?
-
succession, and
succession
Answer:
Fire. Fire is one of the most common causes of secondary succession and is an important component for the renewal and vitality of many types of ecosystem.
Harvesting, Logging and Abandonment of Crop Land.
Explanation:
1- After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns, which require high levels of light. These species are often already present in the form of seeds within the soil, or are able to rapidly disperse from nearby areas. In time, slow growing, shade-tolerant, woody species begin to suppress the early successional species, which are in-turn replaced or shaded by large trees, eventually leading to the generation of forests and a climax community.
2- The abandonment of land previously utilized for crops is a common cause of human-induced secondary succession. Land which has been intensively cultivated is often nutrient poor, with the nutrients having been repeatedly removed through harvest or logging. Agricultural processes also often leave the soil vulnerable to high levels of erosion. The abandonment of such land allows plants and animals that were previously unable to inhabit the area to colonize. Early succession of vegetation following the abandonment of farmland is responsible for increases in soil organic content, nutrient density and soil porosity. The addition of shrubs and of root systems within the soils, which follow in later succession, acts as a natural barrier against erosion, thereby allowing for restoration of degraded habitats.
Secondary succession is a type of ecological succession in which plants and animals recolonize a habitat following a significant disturbance, such as a devastating flood, wildfire, landslide, lava flow, or human activity.
Thus, Primary succession, in which a biological community emerges where none previously existed, is distinguished from secondary succession.
Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs.
Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance and animals.
Thus, Secondary succession is a type of ecological succession in which plants and animals recolonize a habitat following a significant disturbance, such as a devastating flood, wildfire, landslide, lava flow, or human activity.

Binomial nomenclature refers to the method of naming species
with two names, consisting of the____
name and___
name.
Answer:
Genus and species
Explanation:
Binomial nomenclature refers to the method of naming species with two names, consisting of the genus name and species name.
What is Binomial nomenclature?
A binomial system of naming a species is known as binomial nomenclature. A binomial name has two components. They are the particular name and the generic name (genus name) (or specific epithet, in botanical nomenclature).
It frequently takes a Latinized form. Similar terms include binary nomenclature, binominal nomenclature, and two-term naming systems.
Binomial nomenclature, which assigns a single, distinctive name identifier for a particular species across several languages, is crucial for integrating the naming system across life sciences.
Therefore, Binomial nomenclature refers to the method of naming species with two names, consisting of the genus name and species name.

What proportion of each parent plant's genetic material does each offspring plant have?
Answer:
Each gamete comprises half of the organism's chromosomes, or genetic material. As a result, each sperm carries 50% of the father's genes and each egg carries 50% of the mother's genes. This distinguishes gametes from other cells in the body.

There are several factors that lead to genetic variation in organisms. Which of the following is NOT one of those factors?
Answer:
The correct answer is - A. Producing offspring that are genetically identical to the parents
Explanation:
Genetic variation is the difference between the population or individual on a genetic level. If there is a change in the DNA of individuals or among the population, it is genetic variation in these organisms.
There are several factors that result in genetic variation such as random mating, random fertilization, mutation, crossing over during meiosis, and many more. Producing genetically identical offspring to the parents is not a factor as there is no variation is taken place on the genetic level.

Fossils in _______ layers of rock are generally estimated to be _______ than fossils found in the deeper layers. (3 points)
older, younger
newer, younger
older, older
newer, older
Answer:
Answer number 2
Explanation:
So in Geology, Precipitation of rock layers took place over the last hundreds of millions of years...During that process many living organisms have died and are precipitated with the rock layers... Let me explain with an example.
Dinasours went extinct Million years ago while the Dodo bird went extinct a couple of hundred years ago
Would you expect to find Dinasour fossils in newer rock layers or the dodo? lets's say 200m deep? Dodo for sure, Dinasour fossils are waay too old to be found at such shallow deeps that's why fossils in newer layer of rocks are absolutely younger than fossils found at deeper layers
Clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish are just a few examples of the large variety of organisms that can be found in a coral reef. The coral reef and its inhabitants are suffering due to several factors such as pollution, coastal development, sedimentation and destructive fishing practices. What would be the most likely result if some of the species in the coral reef are destroyed? Other organisms would move into the coral reef area The coral reef would be allowed to flourish without so many fish and plants living in and around it. The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance. The waters surrounding the coral reef will become cool with the decreasing number of organisms living there
Answer:
The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance

Which statement est describes how organisms and populations depend on abiotic fertors in
an ecosystem?
A Algae is the main diet of tadpoles.
B Woodpeckers nest in dying trees.
с Worms dig tunnels 'n soll.
D
Gids nest in cattail plants
"Worms dig tunnels in soil", best describes how organisms and populations depend on abiotic factors in an ecosystem. Therefore, option (C) is correct.
What are abiotic factors?Abiotic factors are non-living aspects of the environment that have an effect on living things. In this scenario, worms are considered to be biotic factors; however, the abiotic factor of soil is required for the worms' tunneling activity in the soil. The behavior of worms and the impact that they have on the ecosystem can all be influenced by the moisture level, texture, and nutrient density of the soil.
Therefore, choice (C) illustrates how organisms' ability to survive and perform their roles within an ecosystem is contingent on the presence of abiotic factors.

1.Explain 1 -2 biological benefits that photosynetic plants aboard the ship could provide to the crew.
2. Suggest 2. -3 important considerations and/or measures that the crew should take to ensure the plants ability to survive and photosynthesize. Justify your ideas by explaining why they are necessary.
Can someone please help me on this?
Answer:
Provide food stuff and oxygen.
Explanation:
Making of food and supply of oxygen are the two biological benefits that photosynthetic plants provide to the crew of the ship. The plants make their own food for itself as well as for other organisms and also release oxygen that is produced in the process of photosynthesis. The crew should placed the plants in the sunlight and provides water daily in order to survive and photosynthesize. The sunlight and water are very important because sunlight opens the stomata through which carbondioxide gas enters into the leaves which combines with the water forming glucose and oxygen. Glucose is stored in the plant body whereas some oxygen is used by the plant during respiration and the extra is released in the air through stomata.
