Sea turtles can lay about 100 eggs in a nest. Sadly only a couple of the offspring will survive to adulthood. Which term is being explained in the statement above?

• Artifical Selection

• Camouflage

• Competition

• Over production

What is the correct meaning of 'overproduction'?

• when an environment produces too much resources

• a genetic difference among animals

• finding a mate in the wild

• the struggle for limited resources

Variations are...

• similarities in traits between members of the same species

• differences in traits between members of the same species

• factors that influence natural selection

• not important
