Checklist
- I can define key terms
- I can classify consumers by what they eat (herbivore,
omnivore, carnivore, and scavengers)
- I can explain the chemical process of photosynthesis
- I can analyze a food chain, food web, and energy pyramid
by trophic level (Producers, Primary, secondary, and tertiary
consumers)
- I can relate the water cycle to the ecosystem
- I can justify producers and decomposers role in the
ecosystem
- I can discuss the impact humans have on the carbon cycle
- I can relate the carbon cycle and nitrogen cycle to the
niches of producers, consumers, and decomposers.
