Question

When an invasive species alters the community structure it is introduced to, what can the consequence be?

extinction of economically important species
reduced predation on some native species
increased predation on some native species
all of the above

Answer 1

All of Above

Step-by-step explanation:

Invasive species are the non-native species that are introduced into a new habitat. Some of the invasive species are able to thrive in the new environment by exploiting the available resources as they do not have their competitors and predators in the new habitat.

In absence of any check on their growth, these invasive species compete with native species for resources and may even cause the extinction of valuable, rare and endemic species.

For example, 300 endangered species and 263 other native species are reported to become extinct from Hawaii due to invasive species. Some of the invasive species affect the population and survival of single prey or host species and thereby change the parasitism or predation respectively.
