What makes something alive?It is made up of at least one cellIt uses homeostasis to maintain a balance in
its body (temperature, heart beat/pressure)It can adapt to its environmentIt uses energyIt reproduces/grows

together at the same time and place

Biosphere Where all living things on Earth exist

Food ChainA diagram that shows one pathway of
energy and who eats who.The arrows represent which way the
energy is flowing.It always starts with a producer!
GrassAntBirdSnake
The grass is a producer because it produces its own food by using the sun’s energy.
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?
