Producers

Autotrophs = "self" + "organism with nutritional requirements"


Living things that make their own food; most are photosynthetic & some are chemosynthetic

Slide image

7

Multiple Select

Which of the following organisms are producers? (There may be more than one.)

1

grasses

2

earthworm

3

algae

4

water lily

5

blue jay

8

Photosynthesis

  • photo = "light"

  • Light energy + Carbon dioxide + Water => Glucose & Oxygen

  • EX: grasses, trees, algae

Slide image

9

Chemosynthesis

  • chemo = "chemical"

  • Chemical energy + Carbon dioxide + Water => Glucose

  • EX: hydrothermal vents

10

Consumers

Heterotrophs = "different" + "organism with nutritional requirements"


Living things that get energy by consuming other organisms
