With no natural predators, the lionfish population will become very large.
Some native species of invertebrates will develop a resistance to lionfish venom.

Why is "A" less biodiverse than "B"?
Image "A" is more biodiverse.
Image "A" has many corn plants and this makes it have high "rich" biodiversity.
Image "A" has a lot more plants than image "B"
Even though "A" has a lot of corn plants they are all the same species and makes this a low "poor" biodiverse area.
A bee is critical to the functioning of the ecosystem in which it lives. It affects the survival and abundance of many other species in its community. It is a(n) _______ species.
endangered
threatened
extinct
