Energy Transfer in Ecosystems

Front

What are producers in an ecosystem?

Back

Producers are organisms that create their own food through photosynthesis or chemosynthesis, forming the base of the food chain.

Front

What is a food pyramid?

Back

A food pyramid is a graphical representation showing the relationship between different trophic levels in an ecosystem, illustrating the amount of energy available at each level.

Front

What happens to energy as you move up an energy pyramid?

Back

Energy decreases as you move up the energy pyramid due to energy loss at each trophic level, primarily through metabolic processes.

Front

Who are the primary consumers in an ecosystem?

Back

Primary consumers are herbivores that eat producers (plants) and are the second level in the food chain.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers; they are typically carnivores at the top of the food chain.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

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

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a complex network of interconnected food chains.

Front

What is biomass in an ecosystem?

Back

Biomass refers to the total mass of living matter within a given area or ecosystem, often measured in terms of energy.

Front

What is the significance of trophic levels?

Back

Trophic levels represent the different stages in a food chain, indicating the flow of energy and nutrients through an ecosystem.

Front

What is an example of a primary producer?

Back

An example of a primary producer is a green plant or algae that performs photosynthesis.
