Food Chains:

Food Chains A series of steps by which energy is obtained, used, and changed by living organisms.

PowerPoint Presentation:

Food Chain

Food Webs:

Food Webs Most animals belong to more than one food chain, which means many Food Chains are connected together. Many food chains together form a food web. The food web shows how the sun’s energy moves from plants to animals.

Producers:

Producers Living organism that takes non-living matter and uses it to produce food (energy) for itself with surplus for other living organisms.

Consumers:

Consumers Does not produce its own food.

Decomposers:

Decomposers Living organism which feeds off of dead plants and animals.

PowerPoint Presentation:

Endangered-species is a population of organisms which is facing a high risk of becoming extinct because it is either few in numbers Extinct- the end of an organism or of a group of organisms, normally a species.

PowerPoint Presentation:

Time line of extinct animals

PowerPoint Presentation:

We need to make sure these animals never become extinct! How can we help protect them?

The Environment:

The Environment Predict how changes in the environment would affect a community (ecosystem) of organisms. Predict effects on a population if some of the plants or animals in the community are scarce or if there are too many.

Georgia Performance Standards:

Georgia Performance Standards Life Science S4L1. Students will describe the roles of organisms and the flow of energy within an ecosystem. a. Identify the roles of producers, consumers, and decomposers in a community. b. Demonstrate the flow of energy through a food web/food chain beginning with sunlight and including producers, consumers, and decomposers. c. Predict how changes in the environment would affect a community (ecosystem) of organisms. d. Predict effects on a population if some of the plants or animals in the community are scarce or if there are too many.
