Energy Flow in Ecosystems

Front

What is energy flow in ecosystems?

Back

Energy flow in ecosystems refers to the transfer of energy from one organism to another through food chains and food webs, starting from producers to various levels of consumers.

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight into chemical energy in the form of glucose, using carbon dioxide and water.

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, starting with a producer and ending with a top predator.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how energy and nutrients are transferred among various organisms in an ecosystem.

Front

What are producers?

Back

Producers are organisms, primarily plants and phytoplankton, that produce their own food through photosynthesis and serve as the base of the food chain.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers (plants) to obtain energy.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.

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 energy transfer, such as producers, primary consumers, and secondary consumers.

Front

What happens to energy as it moves up trophic levels?

Back

As energy moves up trophic levels, it decreases due to energy loss through metabolic processes, heat, and waste.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and making them available for producers.
