Sea Otters: Key to the Kelp Forest (pp. 124–125)


Step 1. Questions

You have read about how plants and animals in a kelp forest depend on each other. Sea otters help keep the sea urchin population from increasing too much. By eating sea urchins, sea otters prevent kelp forests from being destroyed.

Write an expository report about how plants and animals in a certain habitat depend on each other. To begin, think of a habitat, such as a desert, a rain forest, or a savannah. Then research the plants and animals that live in the habitat. Here are some questions to guide your research:
  • What habitat would I like to write about?
  • What animals live in the habitat?
  • What are some of the plants that live in the habitat?
  • How do the plants and animals depend on each other for survival?
Are you ready? Begin by visiting the Web sites listed in Step 2. Look for answers to the questions above, and write down what you learn in the boxes.

With teacher supervision, you may use search engines to research other Web sites. You also can research the relationship between plants and animals at the library. When you are ready, follow Steps 3 and 4 to write your report.



Step 2. Research

Research answers to the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!

About Rain Forests
Read about rain forests at this Web site by the Rain Forest Action Network. Read the questions and answers. One question asks about how plants and animals depend on each other in a rain forest.
