FOSS Living Systems Inv. 1 Part 2: Ecosystems and Energy Flow

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food, typically through photosynthesis. Examples include plants like trees and grasses.

Front

What is the flow of energy in an ecosystem?

Back

Energy flows from producers to consumers and then to decomposers.

Front

How do predators and prey interact in an ecosystem?

Back

Predators help keep the number of prey in check, which helps maintain balance in the ecosystem.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem.

Front

Why is energy transfer in a food chain not 100% efficient?

Back

Some energy is lost as heat at each trophic level, making the transfer less than 100% efficient.

Front

What is a consumer in an ecosystem?

Back

A consumer is an organism that cannot make its own food and must eat other organisms for energy.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organisms and waste, returning nutrients to the soil.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, such as producer, primary consumer, or secondary consumer.

Front

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

Back

A food chain is a linear sequence of who eats whom, while a food web is a complex network of interconnected food chains.

Front

What is an example of a primary consumer?

Back

An example of a primary consumer is a herbivore, such as a rabbit or a deer.
