What makes something alive?It is made up of at least one cellIt uses homeostasis to maintain a balance in

Review of terms from field studyWhat is the difference between a habitat and a
niche?
What is the difference between abiotic and biotic?
SpeciesSimilar organisms that can reproduce and

Another word for producer is autotroph.
GrassAntBirdSnake
The ant, bird and snake are called consumers because they have to consume other organisms for energy.
Another name for a consumer is a heterotroph.
Primary consumer-eats the producer (ant)Secondary consumer-eats the primary
consumer (bird)Tertiary consumer- eats the secondary
consumer (snake)
Practice
1. Who is the secondary consumer? How do you know?
2. Who is the autotroph? How do you know?
3. Name the heterotrophs in the food chain.
Food WebsMore complex than a food chain and shows
multiple pathways of energy
Practice1. Who are the primary consumers in the
food web?2. Who are the secondary consumers?
