Part B

What evidence supports your answer to Part A?

• It rains every day in the rain forest ecosystem, which provides the fig with enough water to survive

• The rain forest flower does not receive much sunlight, so the fig must grow taller than other trees

• Producers, like the fig, make their own food, while consumers obtain food from other organisms

• Plants convert carbon dioxide, water, and sunlight into glucose, which are living components in the rain forest ecosystem

• Collecting net

• Magnet

• Microscope

• Telescope

After observing an ecosystem, a student writes the following conclusion in a notebook.

-Ecosystems are only made of living things.

Is the student's conclusion logical?

• Yes, because ecosystems are made of living things that interact

• No, because ecosystems are made of living and nonliving components

• Yes, because ecosystem is another name for habitat

• No, because an ecosystem has nothing to do with living things
