20.3 Energy in Ecosystems

Producers vs. Consumers

Multiple Choice

What resource flows through ecosystems?

• matter

• energy

Multiple Choice

What resource cycles through ecosystems?

• matter

• energy

Cycle vs. Flow

• CYCLE

• Type of Material: matter (EX: water & carbon)

• FLOW

• Type of Material: energy (EX: sun & food)

Producers

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

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

Multiple Select

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

• grasses

• earthworm

• algae

• water lily

• blue jay

Photosynthesis

• photo = "light"

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

• EX: grasses, trees, algae

Chemosynthesis

• chemo = "chemical"

• Chemical energy + Carbon dioxide + Water => Glucose

• EX: hydrothermal vents

Consumers

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

Living things that get energy by consuming other organisms

Multiple Select

Which of the following organisms are consumers? There may be more than one.

• grasses

• turtle

• earthworm

• algae

• water lily

Herbivore

Eats only plants

Carnivore

Eats other animals

Omnivore

Eats both plants & animals

Detritivore

Eats remains of dead organisms

Decomposer

Breaks down/absorbs dead

organic materials
