One way of representing the structure of an ecosystem is through ecological pyramids. Ecological pyramids represent the amount of organisms, biomass or energy at each tropic level, which most often is in a pyramidal shape. Why are most visual representations of ecosystems in the shape of a pyramid?
Select one:
a. Producers use a low amount of sunlight and produce a high amount of energy for all other organisms.
b. Very large carnivores (for example, wolves) have the most energy available to them from the trophic levels below.
c. The large number of primary consumers supplies a large amount of energy for fewer autotrophs.
d. At each trophic level, energy is lost (as heat) in the transfer of energy from one trophic level to another.

Which of the two kingdoms of bacteria are more similar to humans?
https://www.biology-pages.info/A/Archaea.html
Archaebacteria and eubacteria. Eubacteria are more common on earth while the archeabacteria are not despite their existence in harsh environment they have been found in human digestive system in the gut
kingdoms of bacteria are more similar to humans are archaebacteria and both are in symbiotic association as well. Kingdom archaebacteria both are the descendants species.
What is archaebacteria ?The bacteria which are the species which developed differently from the group of blue green algae and totally evolved differently.
Archaebacteria are the species with tRNA and absence of cell walls. These are the species with the extreme adaptations.
Halophiles are the species which are present in the salty areas, methanogens present in the marshy areas, thermophiles present in the most hot temperatures.
The kind of adaptation shows the extreme advancements along with the special structures present for the survival.
Archaebacteria are in symbiotic association where these show the relation between human gut and these are present in the intestinal areas of human body.
Therefore both are descendants and thus very similar to each other along with the symbiotic association to each other.

A gene has 2 alleles, R & B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls look at the picture! I will mark whoever sounds best the brain! Ty!
Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30
Which group of organisms can display the most significant adaptations to their environment in the shortest period of time?
A. Bacteria
B. Fish
C. Insects
D. Mammals
Answer:
A. Bacteria
Explanation:
Displayed by how rapidly antibiotic resistance can develop, bacteria are the organisms that can make the quickest, significant adaptations.
Bacteria also reproduce by binary fission, where one bacteria becomes two.
This method of reproduction occurs rapidly, meaning that bacteria grow exponentially, as each bacteria will double. Over time, this will create a huge population.
This ability to reproduce quickly into a large population means that there is a greater chance for diverse mutations to appear. Some of these mutations will be helpful, and allow the bacteria to survive and reproduce when there are changes to their environments.
These mutations will lead to quick adaptations to the environment.
So, the correct answer is A. Bacteria
Bacteria can display the most significant adaptations to their environment in the shortest period of time.
What are bacteria?Bacteria are the species that can make the quickest, most substantial modifications, as demonstrated by how quickly antibiotic resistance can emerge.
Bacteria can also divide in two through a process known as binary fission.
As a result of this quick process of reproduction, bacteria multiply exponentially since each bacterium doubles in size. This will eventually result in a vast population. With such rapid population growth, there is a higher likelihood that different mutations will manifest themselves.
Therefore, Bacteria can display the most significant adaptations to their environment in the shortest period of time.

Is climate change reversible? Explain your answer.
Answer:
Yes. While we cannot stop global warming overnight, or even over the next several decades, we can slow the rate and limit the amount of global warming by reducing human emissions of heat-trapping gases and soot (“black carbon”).
If all human emissions of heat-trapping gases were to stop today, Earth’s temperature would continue to rise for a few decades as ocean currents bring excess heat stored in the deep ocean back to the surface. Once this excess heat radiated out to space, Earth’s temperature would stabilize. Experts think the additional warming from this “hidden” heat are unlikely to exceed 0.9° Fahrenheit (0.5°Celsius). With no further human influence, natural processes would begin to slowly remove the excess carbon dioxide from the atmosphere, and global temperatures would gradually begin to decline.
Explanation:
I just want to put this out there this does belong to Author: David Herring and Rebecca Lindsey but I hope their answer can help you with your question.
Answer:
Yes to some extent because if we stop the usage of co2 and other harmful substances then global warming will stop and the ozone layer will start to heal itself up. But for this we must stop polluting and ban plastic products and the usage of cfc's and DDT. We also must plant new trees everyday and stop deforestation. We can use cycles or walk to travel to places rather than using cars. Then gradually after many years the climate change will be reversed. We need to work hard. In this corona virus lockdown the nature was healing up a bit.

What are the behavioral adaptions of an animal from the ocean, animal from the desert, animal from antartica and animals from rain forest
Answer:
1. Some fish like stargazer fish hide in rocks and sand to catch prey; some paralyze other fishes or some other ocean animal for safety and food, some like remora fish attach to larger fishes like sharks for protection and food.
2. Some desert animals like kangaroo rats can survive their whole lives without drinking water as they obtain all the moisture they need from the food in their diets.
3. Emperor penguins found in Antarctica form large, ever-moving huddles that allow them to share body warmth, and shelters them from the cold wind.
4. The sloth, an animal found in treetops uses camouflage and moves very slowly to make it difficult for predators to spot.
Explanation:
Adaptation refers to characteristics that help an organismmto be better suited for survival in their environment. Some adaptations may be physical such as the possession of limbs for movement by some animals, physiological such as production of toxins by some plants to avoid being eaten, or behavioural such as building a nest by birds
1. Fishes are animals that live in the ocean. Behavioural adaptations are the way different fish act to survive. Some fish like stargazer fish hide in rocks and sand to catch prey, some paralyze other fishes or some other ocean animal for safety and food, some fish like remora attach to larger fishes like sharks for protection and food.
2. Animals from the desert adapt to the hot desert environment by only coming out at night while hiding in burrows during the day. Some desert animals like kangaroo rats can survive their whole lives without drinking water as they obtain all the moisture they need from the food in their diets.
3. Antarctica is found in the world's coldest region, the South pole. Animals found in this region show various adaptations in order to survive the extreme cold conditions. Antarctic animals have unique behavioural adaptations that help them survive the harsh winter. Emperor penguins found in Antarctica form large, ever-moving huddles that allow them to share body warmth, and shelters them from the cold wind.
4. The rainforests are known for plenty of rainfall, abundance of animal and plant life. Due to these unique characteristics of the rainforests, animals have learnt to survive due to the competition for food and abundance of predators. The sloth, an animal found in treetops uses camouflage and moves very slowly to make it difficult for predators to spot.
