1. Food Webs

2. Energy to Live In order to live animals need energy.
Some animals get the energy they need to live from eating plants and other vegetation.
Some animals get their energy from eating other animals.
Some animals eat both plants and other animals.

3. Herbivores Animals that eat plants are called Herbivores.
Herbivores have evolved to eat plants.
They have specialized teeth and stomachs to enable them to get the energy they need from plants.

4. Carnivore Animals that eat meat are called Carnivores.
Carnivores have evolved to eat meat.
They have specialized teeth and stomachs to enable them to get the energy they need from the bodies of other animals.

5. Omnivore Animals that eat plants and meat are called Omnivores.
Humans are omnivores.
Omnivores have teeth and stomachs that enable them to eat and digest both plants and meat.

6. Food Chain
A food chain is a pathway of food and energy through an ecosystem.
Food chains use arrows to show what animals eat.
Eaten by:
Eaten by:

7. Food Webs Most animals belong to more than one food chain.
Two or more food chains put together makes a food web.
The food web shows how the sun’s energy moves from plants to animals, then to other animals.

8. Terrestrial Food Web
A terrestrial food web shows the feeding relationship in a land ecosystem.
A food web for water is called an aquatic food web.

9. Producers Nearly all food webs start with a green plant.
Green plants are called producers because they produce or make their own food.

10. Consumers
All animals are consumers because they do not make their own food.
Some consume plants to get the energy they need to live, others consume other animals.

11. Prey
Animals that are eaten by other animals are called prey

12. Predators Animals that eat other animals are called predators.
Some animals are predators and prey.

13. Interconnectedness
As food moves between water and land, energy is transferred from aquatic to terrestrial ecosystems. For example, when a insect emerges from a stream, it can be eaten by a forest bird. By catching the insect, the bird has transferred energy from the stream ecosystem (aquatic) to the forest ecosystem (terrestrial).
