Front

What is the role of photosynthesis in the carbon cycle?

Back

It converts carbon dioxide into organic compounds, providing energy for living organisms.

Front

What is an algal bloom?

Back

A rapid increase in the population of algae in water bodies, often due to nutrient overload.

Front

What is the greenhouse effect?

Back

The warming of Earth's surface due to the trapping of heat by greenhouse gases.

Front

What are limiting nutrients?

Back
