Answer 2

Answer:

The tadpole population would decrease.

Explanation:

A food web shows how organisms produce and depend upon each other for food. In an ecosystem, when the population of one organism changes, it can affect the population(s) of other organisms.

In this food web, tadpoles depend upon algae as a food source. If algae were removed from the ecosystem, then the population of tadpoles would likely decrease due to a lack of available food.
