Why is there diversity of life on Earth? A. to encourage organisms to compete with each other B. so that organisms create unique homes C. so that living organisms can survive and reproduce D. so that young organisms can recognize their parents

C. so that living organisms can survive and reproduce.

Explanation:

Every living organism cannot live in the same conditions like a polar bear in the desert could not survive and reproduce so they'd become extinct so we need diversity so every living organism has food they need and shelter and right climate.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
