Disscus the importance of phytoplankton to the composition of the earth's atmosphere?​
Evgesh-ka [11]

Answer:

Phytoplankton are essential for atmospheric and climate regulation.

Explanation:

Phytoplankton are autotrophs, they use solar energy, along with inorganic carbon and water to produce their own food source via photosynthesis. During photosynthesis, they also produce oxygen, integral for the planet's atmospheric composition.

At their large biomass, phytoplankton contribute to a majority of the oxygen used by consumers (most animals).

             6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Along with fossil fuels, human agricultural practices have contributed large amounts of CO2 to the atmosphere, This causes global warming, a major environmental crisis- global warming also leads to landmass loss, biosphere disruption and reduces biodiversity in mass extinction events.

Phytoplankton carbon cycling produces organic matter which functions as carbon sinks in our oceans. Thus, as phytoplankton use large amounts of CO2, they help combat warming cycles, along with producing O2 in atmospheric and climate regulation.
