Question

2 in an ecosystem, a disease greatly reduces the rabbit population. what is the most likely effect on the food web?
a the hawk population will increase because there are fewer rabbits.
b the sun will provide less energy to the ecosystem.
c the fox population may decrease because it has less food to eat.
d the grass population will decrease because there are fewer rabbits.

Explanation:

Rabbits are a food source for foxes. A large drop in rabbit population means less food for foxes, so their population may decrease. Hawks would also lose a food source, so their population would not increase. The Sun's energy input to the ecosystem is unaffected by rabbit populations. Fewer rabbits eating grass would lead to an increase, not decrease, in grass population.

Answer:

C. The fox population may decrease because it has less food to eat.
