Question
If the Indian hare population (Fig. 12.20) drops because of a disease, how would it affect the number of other organisms?
Show answer
Answer
Predators of the hare would get less food; grass may grow more.
Explanation
- Foxes and eagles eat hares, so their food would reduce.
- So their numbers may fall, or they shift to other prey like deer.
- Grass and plants eaten by hares may grow more.
- This shows how one change spreads across the food web.
A drop in one species shifts many others in the web.
