Ecology and Food Web Quiz

What does a food web accurately show?

• Single food chains in an ecosystem

• The feeding relationships among organisms in an ecosystem

• Only herbivores in an ecosystem

• The lifespan of organisms in an ecosystem

Organisms in a food web usually feed on:

• Only one type of organism

• More than one type of organism at different trophic levels

• Only producers

• Only carnivores

What does an ecological pyramid illustrate?

• The lifespan of organisms

• The structure of the trophic levels in a food chain

• The geography of ecosystems

• The size of organisms

Which is NOT a type of ecological pyramid?

• Pyramid of Energy

• Pyramid of Numbers

• Pyramid of Color

• Pyramid of Biomass

Producers are:

• Organisms that consume other organisms

• Autotrophic organisms that make their own food

• Heterotrophic organisms that recycle nutrients

• Organisms that feed only on dead matter

Phototrophic organisms make their food using:

• Chemicals other than water

• Photosynthesis using chlorophyll

• Eating other organisms

• Absorbing sunlight directly

What is the formula for photosynthesis as shown?

• Sugar + Oxygen = Carbon Dioxide + Water + Sunlight

• Carbon Dioxide + Water + Sunlight = Sugar + Oxygen

• Water + Sugar + Sunlight = Carbon Dioxide + Oxygen

• Oxygen + Carbon Dioxide = Sugar + Sunlight

Chemotrophic organisms use chemicals such as:

• Hydrogen Sulfide (H2S)

• Oxygen

• Chlorophyll

• Glucose

Consumers are:

• Organisms that produce their own food

• Organisms that recycle nutrients in the soil

• Heterotrophic organisms that must eat other organisms

• Organisms that perform photosynthesis

Which is NOT a type of consumer?

• Herbivore

• Carnivore

• Omnivore

• Producer
