What is the primary factor affecting photosynthesis in aquatic ecosystems?

Back

The most photosynthesis occurs between 8-12 hours after sunrise due to optimal light conditions.

What is the role of producers in an ecosystem?

Front

What is biomagnification?

Back

Biomagnification is the process by which the concentration of toxins increases in organisms at each successive level of the food chain.

Front

What is the significance of abiotic factors in an ecosystem?

Back

Abiotic factors influence the living conditions and survival of organisms within an ecosystem.
