• By using sunlight, air, and water to make their own food

• By breaking down dead plants or animals

• By eating the sun

How does a consumer obtain(get) the nutrients it needs?

• By using sunlight, air, and water to make its own food

• By breaking down dead plants and animals

• By eating plants and other animals

• By exercising regularly

Bacteria gets its energy by breaking down dead organisms, so it is a:

• Producer

• Consumer

• Decomposer

Which of the following BEST describes grass?

• Producer

• Consumer

• Decomposer

• Scavenger

A cow is an example of a:

• Producer

• Consumer and an herbivore

• Decomposer

• Consumer and a carnivore

If organisms didn't decompose(decay) after they die, what would happen?

• Ecosystems would become unsafe and unlivable(not able to be lived in) because dead organisms would pile up and nutrients would NOT be returned to the soil

• Nothing, everything would be the same

• Ecosystems would be safe because there would be no bacteria at all

• Parents would have to clean up all the dead organisms and throw them in the trash

Which type of organism is responsible for recycling (returning) the remains of a dead plant or animal to the soil?

• Producer

• Consumer

• Decomposer

• Scavenger

Some organisms must get energy by eating other organisms.  These organisms are called consumers.   Consumers can be organized into three groups: 

• producers, decomposers, and cats
• herbivores, producers, and omnivores
• omnivores, consumers, and producers
• herbivores, carnivores, and omnivores.

Herbivores are consumers that eat only _________. 

• plants
• birds
• cats
• meat

Carnivores are consumers that eat only other animals. Some examples of carnivores are...

• tigers and sharks
• birds and tigers
• eagles and goats
• vultures and cows
