Which events are likely to be catastrophic to an ecosystem? Select the two correct answers.
O A. Massive flooding
O B. Steady population growth
O C. Introduction of an unchecked invasive species
D. Spring thunderstorm
O E. Species competition

A and C

Explanation:

Steady population growth, spring thunderstorms, and species competing with each other are not bad for the ecosystem.

But when a massive flood happens it can be devastating and destroy very large parts of the land. Also if we introduce an invasive species that becomes unchecked it can destroy a food supply. If the species has no predator that would thin the numbers it can be truly devastating to an ecosystem.
