Aquatic Ecosystem Organization& Biogeochemical Cycles

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What percentage of the Earth's surface is covered with water?

Back

Approximately 75% of the Earth's surface is covered with water.

Front

What are the main processes of the water cycle?

Back

The main processes of the water cycle include evaporation, condensation, precipitation, and transpiration.

Front

What is the impact of burning fossil fuels on water quality?

Back

Burning fossil fuels increases the acidity of water, affecting the pH level.

Front

What is adhesion in the context of water?

Back

Adhesion is the property of water that allows it to stick to other substances, such as water molecules sticking to a leaf.

Front

What is cohesion in the context of water?

Back

Cohesion is the property of water that allows water molecules to stick to each other, which is responsible for surface tension.

Front

What is the role of nitrates in aquatic ecosystems?

Back

Nitrates are nutrients that can promote plant growth in aquatic ecosystems, but excessive amounts can lead to algal blooms.

Front

What is the significance of dissolved oxygen in water?

Back

Dissolved oxygen is crucial for the survival of aquatic organisms, as it is required for respiration.

Front

What is the process of evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and then released as vapor through pores in leaves.
