Question

which of the following is an example of a trophic cascade? a) a population boom of herbivores after predators are removed b) a forest fire destroys trees c) a farmer plants crops in rows d) a new species is discovered

Explanation:

A trophic cascade is an ecological phenomenon triggered by the addition or removal of top - predators and involving reciprocal changes in the relative populations of predator and prey through a food chain. When predators are removed, herbivores experience a population boom, which is a classic example of a trophic cascade. A forest fire is a natural disaster, a farmer planting crops is an agricultural activity, and discovering a new species is just a biological discovery, none of which are trophic cascades.

Answer:

A. A population boom of herbivores after predators are removed
