Food Chain Key Terms

• Producers-– Photosynthesis:

• Primary consumers-– Cellular respiration:

• Secondary consumers-• Tertiary consumers-• Herbivore-• Carnivore-• Omnivore-• Decomposer-

Common Producers(Phytoplankton/Photosynthesize)

More phytoplankton!

Super cool phytoplankton : DIATOMS!

Microscopic Stuff

Amoeba-omnivores Paramecium- eat bacteriaAmoeba Feeding Footage

Common Primary Consumers (Zooplankton)Daphnia (water flea) Footage

Snails (not zooplankton)primary consumers

• Right handed (dextral) pollution sensitive

• Left handed (sinestral) pollution tolerant,

• EX: Pouch Snails

Scud (zooplankton)Footageprimary & secondary consumer

omnivore & nocturnal

Copepods (zooplankton) Footage(primary & secondary consumer)

omnivore

Ostracod (zooplankton) Footageprimary & secondary consumer

omnivoresome bioluminescent (glow blue at night in Caribbean)

some parthenogenic (drought resistant eggs-come back to life)

Planaria Footagesecondary consumer

(& they will eat dead organisms too)regenerate

Nematode Footage(decomposers)

Rotifer Footage"wheel bearer" crown of cilia

omnivores (but small enough to fit in tiny mouth)
