When organisms are better adapted to their environment they will survive and reproduce more successfully than organisms less adapted. This process is called what?

Back

Natural Selection

The table shows the survival rate of two types of beetles in the same environment over a period of three years. Which statement about the beetles in this environment is best supported by the data? Options: Brown beetles have a shorter life cycle than green beetles have, Green beetles are more fit for their environment than brown beetles, brown beetles undergo more unfavorable mutations than green beetles.

Back

Green beetles are more fit for their environment than brown beetles

Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species L. clamitans clamitans?

Back

It increases the probability that some offspring will survive long enough to reproduce.
