What does the word ecology (生态) mean? It was 1 by Ernst Haeckel, a German biologist. It means "the study of the house". The "house" is our 2, earth. Earth is home for all living things—humans, animals, plants, and even tiny microbes (微生物). An ecologist is a scientist who studies the 3 between organisms (生物) and their environment. The environment is an organism's surroundings. It may 4 water, gases, rocks, and temperature.
An ecologist once asked a boy 5 he thought about protecting the environment. The boy said, "You go into the forest and look for somebody who wants to cut down a tree. You stop him and tell him how 6 trees are. They are good for natural beauty, saving soil, and giving shelter to birds and other animals." "Good answer," said the ecologist, "7 it may not be easy to find a woodcutter to talk to. Also, remember that sometimes it's 8 to cut down a tree. If we cut down too many trees, the forest will disappear. If we don't cut down any trees, we won't get any resources from the forest. We have to find the right 9." The boy agreed, "We need the forest's 10 for wood and paper or we might not have desks or notebooks for school."
"Exactly—and school is a good place to learn about ecology," added the ecologist. "Then you will know how to protect the natural environment."
