Question

What is the role of phytoplankton in the oxygen cycle?

1) rust metal
2) consume oxygen and produce carbon dioxide
3) convert oxygen to ozone
4) consume carbon dioxide and produce oxygen

Answer 1

Phytoplankton play a vital role in the oxygen cycle by consuming carbon dioxide and producing over 50% of the Earth's oxygen through photosynthesis, also helping maintain the protective ozone layer.

Step-by-step explanation:

Phytoplankton play a vital role in the oxygen cycle by consuming carbon dioxide and producing over 50% of the Earth's oxygen through photosynthesis, also helping maintain the protective ozone layer. The role of phytoplankton in the oxygen cycle is fundamental. These microscopic photosynthetic organisms consume carbon dioxide and produce oxygen. Phytoplankton are crucial because they generate over 50% of the Earth's oxygen through the process of photosynthesis.

During this process, they absorb carbon dioxide from the atmosphere and release oxygen, which is essential for the survival of aerobic organisms, including humans. This also contributes to maintaining the ozone layer that protects life on Earth from harmful ultraviolet (UV) radiation.
