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.
What are you trying to find? That is a pedigree
For the first question, I believe it's 36. For the second question, it is oxygen, as oxygen is essential for aerobic processes. For the last question, the summarized cellular respiration equation is the 2nd one.
