The answer is: D. all of the above.
When Earth receives energy from the Sun, some energy is reflected back into space, some is absorbed by the atmosphere, and some is absorbed by land and water on Earth's surface.
Earth's Energy balance describes how the incoming energy from the sun is used and returned to space. If incoming and outgoing energy are in balance, the earth's temperature remains constant. So it’s B
The principle of competitive exclusion states that two species cannot coexist in the same habitat.
<h3>What is
competitive exclusion?</h3>
The competitive exclusion principle, often known as Gause's law, is a theory in ecology that holds that two species competing for the same scarce resource cannot coexist at constant population levels. One species will eventually outnumber all others if it has even a modest edge over the others. This results in the weaker competitor's extinction or an evolutionary or behavioral shift in favor of a different ecological niche. The adage "complete competitors cannot coexist" is a paraphrasing of this idea.
Although he never created it, Georgy Gause is traditionally credited with coming up with the competitive exclusion principle. The natural selection theory put forward by Charles Darwin already incorporates the concept.
The status of the principle has fluctuated during the course of its history between

We de-starch leaves so as to remove the starch produced in it during photosynthesis stored as food. Removing the starch would help us to infer our observations clearly as there is no change or substance that would effect the experiment we want to carry out. For example , the indicators we use might give blue-black or green colors just because of the presence or absence of starch.
