The amount of light and amount of darkness effects how long the animals have
time to eat. Like an owl who eats at night has more darkness in the winter to
hunt than in the summer.

The heat and light determine what kind of food there is for the animal to eat.
Kelsey and Ashley

Some animals eat other animals and the animals that are eaten might only be out
in the day time. That means they only have a certain amount of time to catch
them so they will become extinct. When animals become extinct it effects the
food chain.
