Flow of Energy

Front

What is the flow of energy in an ecosystem?

Back

The flow of energy in an ecosystem refers to the transfer of energy from one organism to another through food chains and food webs, starting from producers to consumers and decomposers.

What are producers in an ecosystem?

Back

Producers are organisms that make their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that obtain energy by feeding on other organisms, including herbivores, carnivores, and omnivores.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how energy and nutrients circulate within an ecosystem.

Front

What is the significance of the pyramid of energy?

Back

The pyramid of energy illustrates the amount of energy available at each trophic level in an ecosystem, showing that energy decreases as it moves up the pyramid.

Front

What happens to the population of consumers if a producer population decreases?

Back

If the population of producers decreases, the population of consumers that rely on them for food will also decrease due to lack of available energy.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the organism's role in the flow of energy, such as producer, primary consumer, or secondary consumer.

Front

What is an example of a primary consumer?

Back

An example of a primary consumer is a rabbit, which feeds on plants (producers).
