What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow through different trophic levels.

What is the role of producers in an ecosystem?

Back

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

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

Back

Energy decreases significantly, with approximately 90% of energy lost as heat and through metabolic processes at each level.

What is the significance of keystone species in an ecosystem?

Back

Keystone species have a disproportionately large impact on their environment relative to their abundance, helping to maintain the structure of the ecosystem.

How does the removal of producers affect an ecosystem?

Back

Removing producers can destabilize the food web, leading to declines in populations of consumers that rely on them for energy.

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

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a more complex network of interconnected food chains.

Front

What is the energy pyramid?

Back

An energy pyramid is a graphical representation showing the energy available at each trophic level in an ecosystem, typically decreasing from the base to the top.

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers; they are typically carnivores or omnivores.
