  It helps the hermit crab attract a mate.

• It protects the hermit crab from predators.

• It allows the hermit crab to move more easily.

Natural disasters, environmental changes, and humans can all have an effect on the growth of a population. Which of the following would cause a population of animals to increase?

• When a drought occurs, many plants and animals die.

• When forests are cleared for human use, animals and plants do not have habitat.

• 
  The number of predators in the population's ecosystem decrease. 

•
