Question

use the information below to fill in column 3 and to create a food web on the next slide.
organisms\thow it gets energy\tare they a producer, herbivore, omnivore or a carnivore?
phytoplankton\tfrom the sun\t
seaweed\tfrom the sun\t
zooplankton\teats phytoplankton\t
crab\teats phytoplankton and zooplankton\t
herring (fish)\teats seaweed and zooplankton\t
seal\teats herring and crab\t
dolphin\teats herring and crab\t
shark\teats herring, seal\t
orca\teats herring and seal\t

Explanation:

Step1: Analyze Phytoplankton

Phytoplankton gets energy from the sun (producer, as it makes its own food via photosynthesis). So it's a producer.

Step2: Analyze Seaweed

Seaweed gets energy from the sun (producer, photosynthesis). So it's a producer.

Step3: Analyze Zooplankton

Zooplankton eats phytoplankton (herbivore, as it eats producers).

Step4: Analyze Crab

Crab eats phytoplankton and zooplankton (omnivore, eats both producers and consumers).

Step5: Analyze Herring (Fish)

Herring eats seaweed and zooplankton (omnivore, eats producer and consumer).

Step6: Analyze Seal

Seal eats herring and crab (carnivore, eats other consumers).

Step7: Analyze Dolphin

Dolphin eats herring and crab (carnivore, eats other consumers).

Step8: Analyze Shark

Shark eats herring, seal (carnivore, eats other consumers).

Step9: Analyze Orca

Orca eats herring and seal (carnivore, eats other consumers).

Answer:

Organism	Are they a producer, herbivore, omnivore or a carnivore?
Seaweed	Producer
Zooplankton	Herbivore
Crab	Omnivore
Herring (Fish)	Omnivore
Seal	Carnivore
Dolphin	Carnivore
Shark	Carnivore
Orca	Carnivore

For the food web: Producers (Phytoplankton, Seaweed) → Zooplankton (eats producers) → Crab (eats producers and Zooplankton), Herring (eats Seaweed and Zooplankton) → Seal, Dolphin (eat Herring and Crab) → Shark, Orca (eat Herring, Seal). Connections: Phytoplankton → Zooplankton, Phytoplankton → Crab; Seaweed → Herring; Zooplankton → Crab, Zooplankton → Herring; Crab → Seal, Crab → Dolphin; Herring → Seal, Herring → Dolphin, Herring → Shark, Herring → Orca; Seal → Shark, Seal → Orca.
