food in this ecosystem?

• Both the lizard population and the hawk population will increase.

In a food chain, foxes are consumers of rabbits and mice. If the mice

population suddenly decreases, what will most likely happen to the

number of foxes?

• The number of foxes will increase because they will eat fewer rabbits.

• The number of foxes will stay the same because they will eat more

  rabbits.

• The number of foxes will decrease because they will be eaten by the

  rabbits.

• The number of foxes will decrease because they will only have one

  remaining food source.
