Trophic Pyramids, Energy Flow (chain/web), Eco Levels (no calc)

Front

What do the arrows in a trophic pyramid represent?

Back

The direction of the energy flow in an ecosystem.

Front

What is the primary role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the trophic pyramid.

Front

What happens to energy as it moves up the trophic levels?

Back

Energy decreases as it moves up the trophic levels due to energy loss at each stage, primarily through metabolic processes.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers; they are typically herbivores.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers; they can be carnivores or omnivores.

Front

What is the role of decomposers in an ecosystem?

Back

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

Front

What might happen if a primary consumer is removed from a food web?

Back

If a primary consumer is removed, the population of producers may increase, while secondary consumers may decline due to lack of food.

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 different organisms are related in an ecosystem.

Front

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

Back

A food chain shows a single pathway of energy flow, while a food web shows multiple pathways and interactions among organisms.
