Any inherited trait that gives an organism an advantage in its environment is called

• a mutation

• evolution

• an adaptation

• natural selection

Why are advantageous traits more likely to be passed on to the offspring?

• Because parents with those traits can teach their offspring

• Because parents with those traits care more about their offspring

• Because parents with those traits can surive and reproduce better

Which could you infer about an ecosystem with high species diversity?

• Its food webs are relatively simple.
