What is a consumer?

• An organism that produces energy through sunlight

• An organism that obtains energy by eating other organisms

• An organism that only feeds on autotrophs

• An organism that decomposes dead matter

What is a food chain?

• A type of model that shows a single pathway through which energy flows in an ecosystem

• A combination of many food chains that shows multiple pathways of energy flow

• A hierarchy that defines trophic levels

• A group of organisms that consume the same resource

What is a food web?

• A type of food chain that involves autotrophs only

• A system of interactions where energy is not transferred

• A combination of many food chains that shows many pathways of energy flow

• A model that shows a single energy pathway in an ecosystem

What is a secondary consumer?

• An organism that feeds on primary consumers

• An organism that only consumes plants

• An organism that is part of the first trophic level

• An organism that does not consume other organisms

What is trophic energy?

• The amount of energy available at a particular level in a food chain or food web

• The amount of energy consumed by autotrophs

• The energy required for photosynthesis

• The energy transferred from producers to decomposers

What is a trophic level?

• The position an organism occupies in a food chain or food web

What is commensalism?

• A type of interaction in which both organisms benefit

• A type of interaction in which one organism benefits and the other is not harmed

• A type of interaction in which one organism benefits and the other is harmed

• A type of competition between two organisms of the same species

What is direct competition?

• A type of competition where one organism avoids another to gain a resource

• A type of competition where organisms aggressively compete for resources

• A type of competition that involves no interaction between organisms

• A type of cooperation between species to obtain resources

What is indirect competition?

• A type of competition where one organism interferes directly with another

• A type of competition where organisms fight over food

• A type of competition in which one organism is better at obtaining or using a resource

• A type of mutual benefit between organisms
