Earth Science And Ecology Quiz: Trivia!

Are you familiar with earth science and ecology? Would you be able to pass this quiz? Ecology studies the relationship among living organisms and their environment. This quiz will be on a cooperative partnership of two species in which both species benefit, what organisms belong to the same food chain, and what predation is. Take this quiz and see how much you know about earth science and ecology.

    In 1989, a tanker carrying oil struck a reef and spilled 11 million gallons of oil in an Alaskan bay. The oil not only spilled into the harbor, but also washed up on the shore line. The spill killed millions of fish, birds that lived on the shore, sea otters, porpoises, seal lions and many whales. Every form of life in the area was affected. Scientists have carefully studied the area and its species since the initial spill to determine both short-term and long-term effects.
