EXTEND AND REFLECT
What kind of teeth do carnivores need to eat other consumers?
Carnivores need sharp teeth to cut through meat.

Herbivores do not need sharp teeth to eat plants, but would have flat teeth to eat plants.
10
Why is it important to properly dispose of waste and dead organisms?
Dead organisms and animal waste are food for bacteria. Bacteria can make people sick, so limiting the amount of bacteria helps keep people healthy.

EXTEND AND REFLECT
What provides the energy at the base of any food chain?
The sun provides energy to the producers at the base of a food chain.

DEVELOP SCIENCE VOCABULARY
What is at the end of a food chain?
Top predators are at the end of a food chain.
15
Humans are at the top of the food chain.
16
SYNTHESIS
How does energy from the sun get to a hawk?
Energy from the sun is used by plants, like grass, to make food.
A rabbit eats the grass, and then a hawk eats the rabbit.

EVALUATE
Which type of consumer has to eat the most to get the energy it needs?
The top predator has to eat the most to get the energy it needs.
20
Which organism in a food chain gets the greatest amount of energy when it eats?
A first-level consumer gets the greatest amount of energy from the producer it eats.
21
Extend and Reflect:
What would happen to a food chain if there were fewer producers?
There would be fewer first-level consumers and much fewer second-level and third-level consumers in the habitat.

Multiple Choice
25
A bird eats a caterpillar. The caterpillar ate leaves. Is this a food chain?
Yes, it is. The leaves are the producer.
