Question

What are three things that lead to an extinction of a species?

Answer 1

Not being able to adapt to the change in their environment. A tragic sudden change: flood, fire, disaster. Sickness/disease, or even being stupid.

Answer 2

Arrival of new predatory or competitive species (cats, rats & foxes, for example). Loss of habitat. Extinction events (massive volcanic eruption/meteor impacts), like the K/T boundary event which caused the extinction of the dinosaurs.

Answer 3

Inability to procreate, inability to adapt to environment, and inability to fight off predators.

Answer 4

1) Lack of food or water

2) Introduction of new predators that a species have little or no defense (also see 3 & 4))

3) Microbes and diseases brought into enviroment (see 2 &4)

4) Overhunting  (see 2 & 3)

5) Lack of adaptation to changes in enviroment.

6) Problems with offspring (some other species stealing eggs, etc.)

7) Any combination above
