State the difference between a producer and a consumer.
What is the similarity between populations and communities?
What is the difference between a food web and a food chain?

2. Do Now Activity #3
Why do consumers depend on cellular respiration to live?
How do producers affect the life of a consumer? Why would consumers, like carnivores, eventually starve without producers?
What type of organism is always at the bottom of the food chain?

3. Section 7-1: ecology Essential Question:
