Eco 7ABC Formative (food chain, web, energy pyramid)

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, starting from producers to various levels of consumers.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the distribution of energy among trophic levels in an ecosystem, typically illustrating that energy decreases as it moves up the pyramid.

Front

What is the 10% rule in ecology?

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 or used for metabolic processes.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) to obtain energy, typically herbivores.

Front

What is a producer?

Back

A producer is an organism, usually a plant, that can make its own food through photosynthesis, serving as the base of the food chain.

Front

What is a carnivore?

Back

A carnivore is an organism that primarily eats other animals for energy.

Front

What is a herbivore?

Back

A herbivore is an organism that primarily eats plants for energy.

Front

What is a trophic level?

Back

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

Front

How much energy is typically available to the next trophic level?

Back

Typically, only about 10% of the energy is available to the next trophic level.
