1. Ecosystems-Cont.

2. Think Aloud

3. Ecosystems are made up of Individual Organisms (living things)

4. Population ( a bunch of the same species)

5. Community-Animals and plants of different species live together

6. Individuals, Populations and Communities make up Ecosystems

7. Energy Transfers Through Ecosystems The number one source of All energy is the SUN

8. Producers start each ecosystem Producers are also called AUTOTROPHS- (Can make their own food).

9. Consumers (Heterotrophs) can not make their own food

10. Decomposers –Break down dead plants and animals

12. A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals

15. Food Pyramid

16. 3 levels of Consumers Herbivore-Only eat plants

17. Omnivore-eats plants and animals

18. Carnivore-only eat meat

19. In every ecosystem, every organism has ROLE (Job) This is called a NICHE The place where an organism(living thing) lives is called its HABITAT

21. Limited Factors in Ecosystems Environmental Factors that limit population sizes. These may be: Water

22. Food

23. Temperature

24. Predators

25. Extinction Lack of resources Over hunting Predator Habitat destruction Natural disaster Deforestation

26. Organisms are Interdependent upon each other What do you think this means?

27. Organisms living in a habitat depend on each other. If one part of a food chain dies out or is greatly reduced, the consumers have to find alternative food, move away, or starve. This then affects more consumers in the same way.
