The partial food web below shows a field ecosystem. Organisms in all ecosystems depend on each other for energy. If too many deer are introduced into this area and overgraze, which consequence will be MOST evident?

• The bats and owls will have more than enough food sources and will no longer need to compete for energy.
• The rabbits and mice will need to move to a new area or risk perishing due to a lack of available resources for energy.
• The lizard population will decrease and leave the owls and bats with very little food.
• The snakes will be over-hunted by the deer as they start to run out of available grass.
