• An organism that primarily consumes meat.

• An organism that primarily consumes plants.

• An organism that can eat both plants and meat.

• An organism that does not consume any food.

What is a food chain?

• A linear sequence of organisms through which nutrients and energy pass as one organism eats another.

• A complex network of food webs that includes multiple species.

• A diagram that shows the energy flow in an ecosystem without organisms.

• A list of all the plants and animals in a specific area.

A type of symbiotic relationship where both species benefit from the interaction.

• Mutualism

• Commensalism

• Parasitism

• Competition

What is commensalism?

• A type of symbiotic relationship where one species benefits and the other is neither helped nor harmed.

• A relationship where both species benefit from each other.

• A relationship where one species is harmed while the other benefits.

What is an ecosystem?

• A community of living organisms and their interactions with their abiotic environment.

• A type of biome characterized by its climate and geography.

• A collection of species that live in isolation from one another.

• A system of renewable resources and energy production.

What is a climax community?

• A temporary community that changes frequently in species composition.

• A stable and mature community that undergoes little change in species composition.

• A community that is dominated by invasive species.

• A community that is in the early stages of ecological succession.

What is parasitism?

• A type of symbiotic relationship where one species benefits at the expense of the other.

• A mutual relationship where both species benefit equally.

• A relationship where one species is harmed while the other is unaffected.

• A relationship where both species are harmed.

What is a limiting factor?

• A factor that enhances the growth of organisms.

• Any abiotic or biotic factor that restricts the numbers, reproduction, or redistribution of organisms.

• A factor that has no effect on the population of organisms.

• A factor that only affects abiotic components of the environment.

What is an autotroph?

• An organism that produces its own food using sunlight or inorganic substances.

• An organism that consumes other organisms for energy.

• An organism that relies on external sources for food.

• An organism that can only survive in aquatic environments.
