WHAT YOU WILL LEARN IN THIS LESSON…

1.What the difference between ecosystem and population is.

2.What the difference between producer, consumer, decomposer the roles they play.

3. How to make Venn Diagram, food chain, and food web.

The study of the interactions between organisms and their environment

Jodi Lock ,March 2010

Every organism has a niche or a role in an ecosystem

based on how it gets energy.

Jodi Lock ,March 2010

Decomposers: organisms that get

energy by breaking down the remains of dead organisms.

Jodi Lock ,March 2010

Producers: organisms that get energy from sunlight and make food.

Ex: plants, plankton, algae, cyanobacteria, some bacteria

Jodi Lock ,March 2010

Consumers: organisms that eat producers or other consumers.

Primary: eat producersSecondary: eat primary consumersTertiary++: eat secondary consumers, etc.

Jodi Lock ,March 2010

Consumers can be:

Herbivores: eat only plantsCarnivore: eat only other consumersOmnivore: eat either producers or consumersScavenger: eat dead animals

5 Levels of Organization:

Organism

Population

Community

Ecosystem

Biosphere

FOOD CHAIN

Food Chain: A model that shows how energy moves through an ecosystem from the producer to the consumers.

Movie Game

FOOD WEB

Food Web: A model that shows how food chains overlap in an ecosystem

Create a Food Web

ENERGY PYRAMID

Energy Pyramid: A way to show how energy is lost through the different levels of a food web.
