What happens to the ecosystem if there is a sudden increase in a primary consumer's population?

Back

An increase in a primary consumer's population can lead to a decrease in the population of producers (like plants) due to overconsumption.

Front

What is a trophic level?

Back

A trophic level is the position an organism occupies in a food chain, which is determined by its feeding relationships.

Front

What is a tertiary consumer?

What is the difference between a community and an ecosystem?

Back

A community is a group of different species living together in one area, while an ecosystem includes the community and the abiotic factors (like water, soil, and climate) in that area.

Front

What role do producers play in an ecosystem?

Back

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

Front

What is a food web?

Back

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

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) and is typically herbivorous.
