What does the word ecology mean It was . .22. . by Ernst Haeckel, a German biologist. He joined two Greek words: oikos, meaning “house”, and logie, meaning “the study of”.

To study a house is to learn how its residents（居民） use it. An ecologist is a scientist who studies the . .24. . between organisms（生物） and their environment. The environment is an organism’s surroundings. It may . .25. . water, gases, rocks, and temperature.

“Good answer,” said the ecologist, “. .28. . it may not be easy to find a woodcutter to talk to. Also, remember that sometimes it’s . .29. . 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 . .30. ..”
“I get it,” the boy said. “We need the forest’s . .31. . 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.”
