Energy in Ecosystems

Front

What is energy flow in an ecosystem?

Back

Energy flow 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.

Front

What are producers in an ecosystem?

Back

Producers are organisms, such as plants and algae, that can make their own food through photosynthesis, forming the base of the food chain.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers. They are the second level in the food chain.

Front

What are secondary consumers?

Back

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

Front

What are tertiary consumers?

Back

Tertiary consumers are predators that eat secondary consumers. They are at the top of the food chain.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

Front

What is a food chain?

Back

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

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers.

Front

What is the 10% rule in energy transfer?

Back

The 10% rule states that only about 10% of the energy from one trophic level is transferred to the next level, while the rest is lost as heat.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.
