Question

using the food web provided, identify two examples of predators, and explain two impacts on the ecosystem if they were individually removed.
predator \t impact on ecosystem

Explanation:

1. For the Fox:

• The fox preys on rabbits and mice. If removed, rabbit and mouse populations will increase due to lack of predation. This overpopulation will lead to overgrazing of grasses, reducing the primary food source for other herbivores.

1. For the Hawk:

• The hawk preys on foxes, mice, and snakes. If removed, snake, fox, and mouse populations will rise. More snakes will increase predation on frogs and birds, while more mice and foxes will put extra pressure on grasses and rabbits.

Answer:

Predator	Impact on ecosystem
Hawk	1. Populations of snakes, foxes, and mice will increase due to loss of this top predator. <br> 2. Rising snake numbers will cause declines in frog and bird populations, disrupting the lower food web.
