Which organisms are considered top predators in a food chain?

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

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a complex network of interconnected food chains.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity enhances ecosystem productivity, stability, and resilience, allowing ecosystems to better withstand environmental changes.

Front

Explain the concept of carrying capacity.

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support without degrading the habitat.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing community but soil remains.
