Unit 9: Interactions in Ecosystems
BIG IDEA
Relationships, systems and cycles exist within environments.
Students will be able to . . .
Provide evidence of ways that organisms interact with living and non-living things in order to survive within their ecosystem.
Illustrate and describe the carbon dioxide-oxygen cycle, including the relationship between plants and animals.
Identify the significance of the carbon dioxide-oxygen cycle to the survival of plants and animals.
Describe and illustrate the flow of energy in a food chain/web, from the Sun to producers, consumers and decomposers.
Describe the role of producers, consumers and decomposers in an ecosystem.
Predict the effects of changes in an ecosystem caused by living organisms, such as the overpopulation of grazing animals and the building of highways by humans.
