• parasite/host

• predator/prey

• herbivore/omnivore/omnivore

• consumer/producer

What is the greenhouse effect?

• It keeps the earth moving on its axis

• When the sun is out its much warmer than when it is not.

• The reflecting and absorbing of energy from the Sun

• Water vapor, carbon dioxide and other gasses help to trap the solar energy and keep it for life on earth

Why is the ozone layer so important?

• Because it refracts most of the sun's heat.
