1. Are most invasive (exotic) species K-selected or r-selected species? Explain your choice and why that makes sense in terms of their ecological success.

The correct answer is "r-selected species".

Explanation:

The terms "k-selected" and "r-selected" species are used to describe two different type of evolutionary strategies. K-selected species are those who have few offspring that are well adapted to its environment and require a lot of resources to growth and survive. On the other hand, r-selected species have a large number of offspring, which not require living on stable conditions and can survive with few resources. The most invasive species are r-selected, since they reproduce very quickly and can adapt to survive to very different ecological conditions.
