Question

How does photosynthesis effect the hydrosphere

Answer 1

Photosynthesis affects the hydrosphere by regulating oxygen and carbon dioxide levels, which are vital for aquatic life. It also contributes to the carbon cycle between the atmosphere and oceans, influencing the formation of carbonate sediments.

Step-by-step explanation:

The process of photosynthesis has a significant impact on the hydrosphere by influencing the levels of oxygen and carbon dioxide in aquatic systems. Photosynthetic organisms, such as algae and aquatic plants, utilize carbon dioxide and sunlight to produce oxygen and glucose. This oxygen is crucial for the survival of aquatic animals. When photosynthetic activity is compromised, it leads to reduced oxygen production, which can deplete oxygen levels and affect the survival of fish and other aquatic animals.

Furthermore, the death of algae can lead to a change in the pH of water, disrupting the metabolic processes of aquatic life. Additionally, the atmosphere and the hydrosphere engage in a continuous exchange of carbon dioxide, which influences the global carbon cycle. The dissolution of CO2 in ocean water contributes to the formation of carbonate and bicarbonate ions, which are essential to marine organisms and the formation of calcium carbonate sediments.

Answer 2

In photosynthesis, plants constantly absorb and release atmospheric gases in a way that creates sugar for food. Carbon dioxide goes in the plant's cells; oxygen comes out. Without sunlight and plants, the Earth would become an inhospitable place unable to support air-breathing animals and people.
