1. Warm up: What happens once in a minute, twice in a moment, and never in a thousand years?

2. Living Things Need Energy

3. The Energy Connection
Organisms can be divided into three groups in their community: producers, consumers, and decomposers.

4. Producers Organisms that use sunlight directly to make food.
Photosynthesis is the process of making food out of sunlight.
Most plants are producers, along with some algae and bacteria.

5. Consumers Organisms that eat other organisms are consumers.
Herbivore- is a consumer that eats plants.
Carnivore- is a consumer that eats animals.
Omnivore- is a consumer that eats both.
Scavengers- animals that feed on the bodies of dead animals.

6. Decomposer
Organisms that get energy by breaking down the remains of other organisms are decomposers.
Bacteria and fungi are examples.
Decay is the process of breaking down matter. Energy is released, and used.
In the process, matter is rearranged into simpler compounds.

7. Slime Mold

8. Food Chains
Food chain is a path of energy from one feeding level to another.

10. Food Webs
All of the food chains in a community link together to form a food web. It shows the many ways energy can flow through an ecosystem.

12. Energy Pyramids Loss of energy along the food chain.
Amount of energy becomes smaller as you go higher.
Organisms use up most energy they take in.
Only energy stored in their tissues can be passed on to the next level.

14. Write your agenda
Get out your notebook
Warm up:
What happens to energy as you get further up a food chain? Why is this so important?
