Answer: 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.
