How is a decomposer also a consumer?

A decomposer consumes the remains of other organisms.

A decomposer only eats consumers

A decomposer consumes only energy, but no matter.

A decomposer only consumes, but does not produce matter.

Which of these accurately describes the role of a decomposer?

Decomposers act as nature’s recyclers.

Decomposers keep consumers healthy.

Decomposers eliminate all unused matter.

Decomposers act as prey for all organisms.

How do producers get their matter and energy from decomposers?

Producers absorb the raw materials that decomposers produce.

Producers borrow their matter and energy from decomposers.

Producers become decomposers in order to get matter and energy.

Why isn’t all of one prey’s matter transferred to the predator that consumes it?

Matter can be lost as carbon dioxide.

Matter can be lost to the environment.

A trophic pyramid is a model that shows

how much energy flows from one stage to the next in a food chain.

how many organisms can exist in a single food web.

how much total energy and matter exists in a single ecosystem.

the rate at which energy and matter is consumed by each consumer in a food chain.

How do trophic pyramids get their shape?

Trophic pyramids get their shape from the loss of energy that happens at each stage.

Trophic pyramids get their shape from the types of organisms that are represented in the pyramid.

Trophic pyramids get their shape because a pyramid is the easiest shape to represent a food web.

Trophic pyramids get their shape from the number of organisms at each point on a food chain.

What do trophic pyramids demonstrate about the flow of energy in an ecosystem?

The amount of energy available to each organism decreases as it flows through the ecosystem.

The amount of energy available to each organism increases as it flows through the ecosystem.

The amount of energy available to each organism varies as it flows through the ecosystem.

The amount of energy available to each organism stays the same as it flows through the ecosystem.

What was the result of the Finnish scientists’ first design to restore Lake Vesijärvi’s clear waters?

Their first solution did not meet the criteria of restoring the lake’s oxygen.

Their first solution met the criteria of restoring the lake’s clarity.

Their first solution violated the constraints of not removing any predators.

Their first solution violated the constraints on time that scientists had to restore the lake.

How did the Finnish scientists who were trying to restore Lake Vesijärvi’s oxygen modify their first design?

Scientists added top predators to the lake.

Scientists removed the predators that consumed the algae.

Scientists increased the population of different colored algae.

Scientists removed all the water from the lake through a filter.

Food web diagrams help scientists understand

how matter and energy flows among populations of organisms in an ecosystem

how food attracts different organisms to a particular ecosystem.

how many species can survive for a given amount of time in an ecosystem.

nothing about how different ecosystems support the organisms that live there.

Look at the diagram. The food chain depicted above represents one chain in many that make up a forest ecosystem food web. What kind of impact will rattlesnake populations have on deer mice?

Rattlesnakes will have a direct effect on deer mice populations, causing them to decline.

Rattlesnakes will have an indirect effect on deer mice populations, causing them to decline.

Rattlesnakes will have a direct effect on deer mice populations, causing them to increase.

Rattlesnakes will have an indirect effect on deer mice populations, causing them to increase.

When a bison eats 8 kg of grass, part of the matter of the grass is used by the bison as its own source of energy and matter. Some of that grass stays in the ecosystem as biomass. Some is consumed by decomposers. What happens to the rest of the matter in that 8 kg of grass?

It is released as waste and carbon dioxide.

It is released as oxygen and carbon dioxide.

In a local forest ecosystem, populations of owls have become endangered. Use the food web diagram to suggest a management change that would help improve owl populations.

Increase deer mouse populations by increasing populations of shrubs and other plants.

Decrease deer mouse populations by reducing the number of shrubs in the forest.

Increase red-tailed hawk populations by increasing rabbit and vole populations.

Increase elk populations by decreasing populations of rabbits that compete for grass

If polar bear populations decline, what could happen to the arctic cod populations?

They will decrease because ringed and harbor seal populations increase.

They will decrease because ringed seal populations decrease.

They will increase because polar bears do not eat ringed and harbor seals.

They will increase because ringed and harp seal populations decrease.

Populations of phytoplankton, such as algae, live on the underside of sea ice. Yet, sea ice is melting. How could this negatively affect polar bear populations?

They will decrease with less algae available to support the food web.

They will increase because the base of the food web is zooplankton.

They will increase with less algae available to support the food web.

They will decrease with more algae available to support the food web.
