Producers & Prey
This term describes the role of an animal that gets hunted.
Prey
A fish that eats smaller fish is called this type of consumer.
Secondary Consumer
The original source of energy in most food webs.
The sun
This term describes organisms that make their own food
Producers
This ocean predator has rows of sharp teeth and smells blood from miles away.
Shark
This term describes the role of an animal that hunts prey.
Predator
Animals that only eat plants or algae are called
Herbivores
These organisms return nutrients to the ecosystem by breaking down waste.
Decomposers
This sea plant looks like long ribbons and grows near the shore.
Seaweed
This kind of animal has a shell and moves slowly on the ocean floor. They are herbivores or carnivores and some are even venomous.
Snail
What is an adult great white shark's primary food source?
Seals and sea lions
An animal that eats both plants and other animals.
Omnivore
This diagram shows how energy moves through a single path.
Food Chain
This green organism floats on water and makes food from sunlight.
Algae
This underwater flowering plant is often mistaken for seaweed, but it has roots, stems, and leaves. It also plays a major role in stabilizing the ocean floor.
Seagrass
This large sea mammal is a top predator and eats seals and fish.
Orca (Killer Whale)
This small animal eats plankton and is eaten by fish.
Zooplankton
This more complex diagram shows many interconnected food chains.
Food Web
These organisms produce oxygen and are food for zooplankton.
Phytoplankton
The number of links in a food chain is usually limited by this.
The amount of energy passed on
In a meadow ecosystem, rabbits eat grass and are hunted by foxes. If a disease wipes out most of the rabbits, what will likely happen to the foxes and the grass over time — and why?
The fox population will decrease due to lack of food, and the grass will increase because fewer rabbits are eating it.
Crabs and lobsters are examples of these bottom-dwelling consumers.
Scavengers
The level in a food web where the energy is the lowest.
Tertiary Consumer
This large green/brown seaweed forms underwater forests and provides food and shelter for many marine animals.
Kelp
A food web in the deep ocean might rely on this instead of sunlight.
Hydrothermal energy or chemosynthesis
ex. geothermal vents
