1. Energy in the ecosystem

2. Learning Scale
Level 4 – Investigate and analyze the relationships between organisms in assigned ecosystems.
Level 3 – Compare and contrast the relationships between organisms.
Level 2 – Describe and explain the roles of producers, consumers, and decomposers in transferring energy in a food web. Identify and describe limiting factors in an ecosystem and their impact on organisms.
Level 1 – With help, define key terms (producer, consumer, decomposer, mutualism, parasitism, commensalism, etc.)

3. Habitat – place where an organism lives
Niche – the role of the organism in its environment

4. Producers make their own food.
Example = Grass
Processes include: Photosynthesis or Chemosynthesis
All energy comes from the Sun.

5. Consumers eat other organisms.
Herbivore – eats plants
Carnivore – eats other animals
Omnivore – eats plants and animals
Detritivore/Decomposers – eat the remains of other organisms.

7. Levels of Consumers Primary Consumer – eats the producer
Secondary Consumer – eats the primary consumer
Tertiary Consumer – eats the secondary consumer

8. A food chain is a model that shows how energy flows in an ecosystem through feeding relationships.

9. How does a food chain model the Law of Conservation of Energy?

10. Think of a Florida ecosystem
Think of a Florida ecosystem. What is one herbivore, carnivore, and omnivore that might be found there?

11. Explain what this diagram shows.
