Answer: C. they cannot reproduce with one another.
Step-by-step explanation:
- We can see two lizards of different species in the same ecosystem because they cannot reproduce with one another and that's why they can easily live in the same ecosystem.
- This is because different species are unable to interbreed and produce healthy offspring. This is because of the mechanism of reproductive isolation, it's like a natural barrier that does not allow them to reproduce.
- We see a variety of lizards in the same place because of this and they live freely.
