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
Jodi Lock ,March 2010
5 Levels of Organization:
Organism
Population
Community
Ecosystem
Biosphere
Jodi Lock ,March 2010
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.
Lorax Video
VENN DIAGRAM
As a class make and discuss a Venn diagram.
Population
Community Ecosystem
