Life of Science part 2

How do plants get their energy?

• by eating other organisms

• by absorbing mineral nutrients from soil

• through a reaction called chlorophyll

• through a process called photosynthesis

Jaden states that animals do not depend on energy from the sun FOR FOOD. How would you respond to this statement?

• I would agree with Jaden because animals do not make their own food through photosynthesis.

• I would agree with Jaden because animals eat other organisms.

• I would disagree with Jaden because animals either eat plants or other animals that eat plants.

• I would disagree with Jaden because animals sun themselves to help keep their bodies warm.

What does a food web show?

• descriptions of how different animals of the same type are related in an environment

• pictures of the different populations of plants and animals in the environment

• the number of plants and animals present in an enviroment

• the different paths that energy follows as it moves through an environment

What do decomposers do?

• produce food through photosynthesis

• break down dead organisms or the wastes of living things

• hunt other animals for food

• change food energy into heat in an animal's body

Which organism is both predator and prey?

• grass

• deer

• hawk

• frog

How is a food web different from a food chain?

• Food webs contain only producers, not consumers.

• Food webs do not include decomposers.

• Food webs contain many different, linked food chains.

• Food webs exist in aquatic environments; food chains exist in terrestrial environments.

How do plants and animals differ?

• Unlike animals, plants do not need gases from the air.

• Unlike plants, animals do not need gases from the air.

• Unlike animals, plants are able to make their own food.

• Unlike plants, animals are able to make their own food.

What is the original source of energy for organisms in a food chain?

• water

• animals

• sunlight

• consumers
