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.

Question is specific and clearly
connects the relationship
between carbon dioxide (CO)
and temperature
Answer:
The Temperature rises as carbon dioxide levels rise. The temperature decreases when the carbon dioxide concentration falls.
Explanation:
A tiny part of the correlation is attributable to the relationship between temperature and carbon dioxide solubility in the surface of the ocean, but most of it is consistent with feedback from carbon dioxide to the environment. These changes are expected to be consistent with Earth's radiative balances and the function of greenhouse gases in climate change. While determining the cause and impact, initially or by some other method, between carbon dioxide and climate, may appear straightforward, it still is extremely difficult to find the cause and effect. Other changes include altered vegetation, earth surface properties, and ice-sheet extent in the glacial climate.
Other paleoclimate representatives allow us to comprehend the role of the oceans in climate change in the past and future. The ocean holds 60 times as much carbon as the atmosphere, and the change in carbon dioxide in the atmosphere is predicted throughout the past several hundred thousand years to be compared to carbon changes in the ocean. While oceans vary far more slowly than the atmosphere, in past CO2 fluctuations the ocean has played a key role and will play a part for millennia in the future.
Finally, paleoclimate data demonstrate that there is not only temperature about climate change. In the past, many other aspects of the climate have altered as carbon dioxide has changed. The snow was lower, the continents dried and the tropical mousses weaker during the glacial ages. Some of these changes may be independent; others may be closely associated with changing carbon dioxide levels. A thoroughness of research is to understand what these changes might occur in the future and how substantial these changes may be.. The Paleoclimatology Program of the NOAA provides scientists with a documentation of previous changes as an approach to understanding future climate change.

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

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.

How is a genesis rock useful to humans?
Answer:
That sample, nicknamed the Genesis Rock, sample number 15415, was an anorthosite, a piece of the moon’s primordial crust. Geologists, hoping to learn more about the moon and its origins, selected the Hadley-Apennines landing site for precisely this reason. While not the oldest lunar sample brought back from the moon, geologists at the Manned Spacecraft Center (now known as the Johnson Space Center) later concluded that this rock was about 4 billion years old

Why do efforts to prevent all fires from occurring in forests actually tend to make these ecosystems more vulnerable to fire?
Answer:
they feed off of the efforts to control the fires on forests
Explanation:
they cause heat trapping for wildfires to grow. These patterns occurred in 1880 as a result, led multiple forest fires that were hard to control and over time increased chances of happening again.

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.
