What is a food web?

Back

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

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organisms and recycle nutrients back into the soil, making them available for producers.

Front

What is a producer in a food chain?

Back

A producer is an organism, usually a plant, that can make its own food through photosynthesis.

Front

What would happen if an oak tree is removed from a forest food web?

Back

Removing an oak tree would greatly impact the food web because it provides food and habitat for many organisms.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose (food) and oxygen.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms where each is eaten by the next, showing how energy and nutrients flow through an ecosystem.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation showing the flow of energy at different trophic levels in an ecosystem.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers; they are usually herbivores.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and then evaporated from the leaves into the atmosphere.
