Answer:
C.) Selective pressure
Explanation:
Selective pressure is a natural process that occurs in nature in which certain phenotypes are favored in certain environments. When we say these phenotypes are favored, this means individuals with these phenotypes have a better chance at survival and reproduction in particular environments. Certain phenotypes may be beneficial in some environments but harmful in others.
Ecosystem an area where plants, animals, and other organisms, co-ordinate for their living. According to energy pyramid, ecosystem can support fewer foxes than grasshoppers.
<h3>What is energy pyramid?</h3>
Energy pyramid is the flow of energy from one tropic level to another which is always erect.
After each level, 90% energy is lost in environment as heat. There is loss of energy at each tropic level.
As foxes comes after grasses in energy pyramid, so the ecosystem can support fewer foxes than grasshoppers.
Thus, the correct option is A.

It is true that r-related species have a short life span and an early reproduction cycle. R-related species also known as r-strategist have a short and simple life span. Due to their simple life span, their nutrient exchange rate with the environment is rapid. Unlike K-selected species, they have the ability to reproduce at a young age. They reproduce a large number of off-springs, but many of their off-springs tend to die before attainment of their reproductive age.
