Which of the following populations would be affected if a wildfire killed most of the producers in this ecosystem?

A.

hawks

B.

snakes

C.

grasshoppers

D.

all of these

Option D) all of these

Explanation:

Since grasshoppers, snakes and hawks are primary, secondary and tertiary consumers respectively, the killing of producers in this ecosystem will deprive ALL OF THEM of food directly or indirectly.

This is because the food chain is presented as grass > Grasshopper ---> Snake ---> Hawks.

- Hence, absence of grass due to wildfire would lead to starvation and death of grasshoppers

- Limited number of grasshoppers lead to starvation and death of snakes

- So also, limited snakes deprive hawks of food.

Thus, all the populations would be affected by the wildfire.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
