Which of the following best describes mutualism?

Both species benefit from the relationship.

One species benefits, and the other is harmed.

One species benefits, and the other is unaffected.

Both species are harmed by the relationship.

Which of the following describes parasitism?

One species benefits, and the other is harmed.

Both species benefit from the relationship.

One species benefits, and the other is unaffected.

A process in which one organism eats another for food.

A relationship where two species live together without affecting each other.

A type of competition between two species.

The process of decomposing dead organisms.

How is predation different from parasitism?

In predation, the predator benefits and the prey is killed. In parasitism, the parasite benefits and the host is harmed but not killed.

In both, one organism benefits and the other is harmed.

Predation involves plants, while parasitism involves animals.

Parasitism is more beneficial for the parasite than predation is for the predator.

What is energy in an ecological context?

The ability to do work, often in the form of heat or light.

The ability of organisms to reproduce.

The ability to move and consume food.

The capacity to interact with other organisms in the environment.

How is energy flow shown in a food web?

By showing the path of energy as it moves from one organism to another.

By showing the relationship between species.

By depicting how energy is stored in an ecosystem.

By illustrating the competition between species for food.

What is the main difference between a food chain and a food web?

A food web shows more complex interactions than a food chain.

A food chain shows only herbivores, while a food web shows all organisms in an ecosystem.

A food web only shows producers and decomposers, while a food chain shows consumers.

A food web shows energy loss, while a food chain does not.

What is an autotroph?

An organism that produces its own food through photosynthesis or chemosynthesis.

An organism that eats other organisms for food.

An organism that breaks down dead organic material.

An organism that hunts and captures prey.

What is a heterotroph?

An organism that depends on other organisms for food.

An organism that can make its own food.

An organism that absorbs nutrients from the soil.

An organism that decomposes dead material.

What could happen in an ecosystem if all the producers were removed?

The ecosystem would collapse, as there would be no source of energy for consumers.

The predators would thrive without competition.

The herbivores would adapt by eating decomposers.

The ecosystem would remain unchanged.

What does an ecological pyramid show?

The amount of energy or biomass at each trophic level.

The relationship between predators and prey.

The competition between different species.

The migration patterns of species in an ecosystem.

What does the 10% rule refer to?

The percentage of energy transferred between trophic levels in an ecosystem.

The percentage of species that survive after primary succession.

The percentage of decomposers in an ecosystem.

The percentage of time organisms spend on each trophic level.

What happens to the energy that is lost at each trophic level?

It is used for metabolism or lost as heat.

It is passed on to decomposers.

What is a trophic level?

The position an organism occupies in a food chain.

The classification of organisms based on their size.

The process of energy storage in an ecosystem.

The level of biodiversity in an ecosystem.

Which of the following is true about primary succession?

It occurs in an area where no soil exists.

It begins with small herbivores.

It is slower than secondary succession.

What happens during secondary succession?

A disturbance wipes out an existing ecosystem, but the soil remains.

New species colonize an area with no previous ecosystem.

The area is destroyed and starts from scratch.

The area undergoes a rapid process of primary succession.

Which of the following describes the climax community in an ecosystem?

A stable, mature community that undergoes little change.

The initial species that colonize the area.

The species that dominate the early stages of succession.

The species most adapted to disturbance.

How does biomass change during primary succession?

It starts low and gradually increases as the ecosystem develops.

It remains the same throughout.

It starts high but decreases over time.

It is highest at the start and decreases as climax species establish.

Which of the following is true about the ecosystem at the end of secondary succession?

It has reached a stable, mature state.

It is similar to the initial ecosystem.

It has no soil, and plants must recolonize.

What is one way that succession can affect biodiversity?

It increases biodiversity as new species colonize.

It decreases biodiversity over time.

It keeps biodiversity constant.

It eliminates biodiversity after a disturbance.

Which of the following would be considered a climax community?

A mature forest with a variety of species.

A desert with little plant life.

A grassland in its early stages.

Which of the following is an example of a disturbance that might lead to secondary succession?

A forest fire that burns down trees but leaves soil.

A volcanic eruption that creates new land.

A glacier retreating, exposing new land.

A new area of land formed from a coral reef.

an organisms that uses sunlight to make its own food

an organism that gets energy from eating other organisms

an organism that gets energy from eating dead organisms, non-living material or waste

an organism that uses chemical energy to make its own food
