Energy flow Review

Front

What do you call an animal that eats both plants and meat?

Back

Omnivores are animals that consume both plant and animal matter.

Front

Why do higher trophic levels in most ecosystems contain fewer organisms than lower trophic levels?

Back

Higher trophic levels contain fewer organisms because the energy available for use decreases as it moves up the food chain.

Front

How much energy is lost at each trophic level?

Back

90% of energy is lost at each trophic level due to metabolic processes and heat.

Front

Where do plants get their energy from?

Back

Plants obtain their energy from the sun through the process of photosynthesis.

Front

What is the diagram that shows many feeding relationships in an ecosystem called?

Back

A food web illustrates the complex feeding relationships among organisms in an ecosystem.

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.

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.

Front

What is the primary source of energy for most ecosystems?

Back

The primary source of energy for most ecosystems is sunlight.

Front

What role do herbivores play in an ecosystem?

Back

Herbivores are primary consumers that eat plants and convert the energy stored in them into a form usable by higher trophic levels.

Front

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

Back

A food chain shows a single pathway of energy flow, while a food web illustrates multiple interconnected food chains.
