Question 16

Herbivores are also known as what?

Answer 16

Primary consumers

Question 17

Why are herbivores also known as primary consumers?

Answer 17

Because they are the first consumers in a food chain.

Question 18

Where can herbivores be found?

Answer 18

In every environment where plants grow.

Question 19

What do carnivores eat?

Answer 19

Eat only other animals

Question 20

In many food chains, herbivores are what?

Answer 20

Food for other animals

Question 21

2. Tertiary Consumers

Question 23

What are carnivores that eat primary consumers called?

Answer 23

Secondary consumers

Question 24

Name some examples of secondary consumers.

Answer 24

Snakes, fish, spiders

Question 25

What are carnivores that eat secondary consumers called?

Answer 25

Tertiary consumers

Question 26

Where are most tertiary consumers found on the food chain?

Answer 26

On top

Question 27

Name some examples of of tertiary consumers.

Answer 27

Hawks, herons, lizards

Question 28

What are animals that eat both plants and animals called?

Answer 28

Omnivores

Question 29

Names some examples of omnivores.

Answer 29

Raccoons, bears, woodpeckers, mice, chickens, and some crabs

Question 30

What can omnivores be?

Answer 30

Both predators and prey

Question 31

Why are predators an important part of the food chain?

Answer 31

They limit the size of the prey populations.

Question 32

Why is reducing the number of prey necessary?

Answer 32

When the number of prey animals is reduced, producers and other resources in an ecosystem are less likely to run out.

Question 33

Why are prey an important part of the food chain?

Answer 33

1. Prey control the populations of producers and some primary consumers by consuming them.
2. They also support predator populations because they are their food source.

Question 34

Predator and prey populations often cycle together. An increase in the size of prey population is often followed by what?

Answer 34

An increase in the predator population.

Question 35

Decomposers break down organisms that are no longer living into what?

Answer 35

Nutrients

Question 36

Some of the nutrients become part of the soil. Who takes these nutrients in?

Answer 36

Organisms such as plants take these in.

Question 37

How do animals get these nutrients?

Answer 37

When they eat these plants.

Question 38

What happens when plants and animals die?

Answer 38

Decomposers break down their bodies and the food chain starts all over again.
