Nature’s recyclers….

Decomposers

Food Chain Order 1. Sun

2. Producers

3. Herbivores

4. Carnivores

5. Scavengers

Herbivores, carnivores, and scavengers are examples of…

consumers

Animals that eat meat and plants are…

Omnivores

Scientists who study the connection among living things specialize in the

science of…

ECOLOGY

Most PRODUCERS are…

PLANTS

An example of POPULATION…

All the oak trees in a forest

Commensalism -

~ An orchid living on a tree branch

Parasitism -

~A tick feeding on an bird

As aphids get food from plants, they make food for

ants. These ants help aphids find new places to eat. This is an example of:

mutualism

Energy moving through an ecosystem can be

represented by 3 things….

Food web

A ________________ contains BOTH a biotic and abiotic environment.

an ecosystem

contains only a biotic environment.

A COMMUNITY…

Living Things:

treesquirrel

Fishbird

Organisms that get energy by breaking down the remains of

the dead organisms are called:

consumer

What is YOUR part in your ecosystem?

What feeds on the bodies of dead

animals?

scavengers

a biome can contain one or more ecosystems.

Relationship between an ecosystem and a biome is…

1. A rainbow trout 2. All the rainbow trout in a stream 3. The water, rocks, and organisms in a

stream 4. All the rainbow trout, other fish, and

insects in the stream

The best example of community

When the people cut down trees, they destroyed the habitats of

the rabbit’s predators.People in a community cut

down trees in a forest so they could use the wood. They cut down many trees each year.

After several years, a

population of rabbits in a nearby field had become so large that the rabbits were causing problems for the

community.
