Front

What is the role of stomata in plants?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange and transpiration.

Front

What is the significance of nitrogen fixation in the nitrogen cycle?

Back

Nitrogen fixation converts atmospheric nitrogen into a form that plants can use, which is essential for their growth.

Front

What is the difference between assimilation and ammonification in the nitrogen cycle?

Back

Assimilation is the process of plants absorbing nitrogen compounds, while ammonification is the conversion of organic nitrogen back into ammonium.

Front

What are the two main types of symbiotic relationships in ecology?

Back

Mutualism and parasitism.

Front

What is the primary function of an estuary in an ecosystem?

Back

Estuaries serve as nurseries for many marine species and provide critical habitat for wildlife.
