100

A group of atoms joined together.

What is a molecule?

100

What do organisms need to live?

Energy storage molecules

100

What causes the extreme changes in the Arctic between winter and summer?

The Earth's tilt

100

What do coral reefs need to survive?

Lots of sunlight

100

Where is most of the life in the rain forest found?

In the canopy

200

All the living things in a place, plus the nonliving things.

What are ecosystems?

200

What do producers use to perform photosynthesis?

Carbon dioxide and sunlight

200

What is the main reason Arctic plants are able to grow so much during the summer?

Constant sunlight (they can perform photosynthesis all day and night)

200

What is the role of algae in the coral reef ecosystem?

Photosynthesis (energy to the coral polyps)
200

What happens when a big tree falls in the rain forest?

A hole is made in the canopy

300

Living things that make their own food.

What are producers?

300

What happens as producers make more energy storage molecules?

Consumers get more energy storage molecules from eating the producers

300

What happens to many plants in the Arctic when the summer ends and the sunlight decreases?

They stop photosynthesis (will also accept "become inactive" or "survive as seeds")

300

What happens if a coral reef does not get enough sunlight?

The algae and coral polyps die

300

Why is there less life on the rain forest floor?

Very little sunlight reaches the ground (hard to do photosynthesis)

400

The process that plants use to turn water and carbon dioxide into oxygen and energy using sunlight.

What is photosynthesis?

400

Name three examples of energy storage molecules mentioned in the text.

glucose, starch, and fat

400

What is one way that some animals survive the winter in the Arctic?

Hibernation

400

What are coral reefs made of?

Coral polyps

400

How do trees and plants in the rainforest canopy get their energy?

Photosynthesis

500

A type of sugar that plants make during photosynthesis

What is glucose?

500

Where does photosynthesis happen? (only producers have them)

Chloroplasts

500

What is one reason, besides the availability of food, that more animals are present in the Arctic during the summer?

Birds and other animals migrate to eat and reproduce.

500

Why do coral reefs need clear water?

So sunlight can reach the reef

500

What happens to the glucose that trees and plants create?

It is stored in the plants and/or used as energy by animals.
