What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, serving as a primary source of energy in a food web.

How many levels are there in a typical trophic pyramid?

Back

There are typically four to five levels in a trophic pyramid: producers, primary consumers, secondary consumers, tertiary consumers, and sometimes quaternary consumers.

Front

What role do primary consumers play in a food web?

Back

Primary consumers are herbivores that eat producers and convert the energy stored in plants into a form that can be used by higher trophic levels.

Front

What happens to the population of producers if the primary consumers increase significantly?

Back

If the population of primary consumers increases significantly, the population of producers may decrease due to overgrazing or overconsumption.

Front

What is a trophic pyramid?

Back

A trophic pyramid is a graphical representation of the distribution of biomass, energy, or numbers of organisms at each trophic level in an ecosystem.

Front

What is the significance of the tertiary consumer in a food web?

Back

Tertiary consumers are important as they help control the population of secondary consumers and maintain balance in the ecosystem.

Front

What is the relationship between carbon and organisms in an ecosystem?

Back

Carbon is a fundamental element that cycles through organisms in an ecosystem, being absorbed by producers and transferred through the food web.

Front

What is the bottom level of a trophic pyramid?

Back

The bottom level of a trophic pyramid consists of producers, which are essential for energy flow in the ecosystem.

Front

How does a decrease in a predator population affect the prey population?

Back

A decrease in a predator population can lead to an increase in the prey population, as there are fewer predators to control their numbers.

Front

What is the role of decomposers in a food web?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem and supporting the growth of producers.
