Explanation:
Anaerobic is a term that refers to the absence of oxygen during a process (biological or chemical) OR in an living organism. For instance: living organisms that break down complex substances in the absence of oxygen are called Anaerobes, and undergo a anaerobic respiration.
Answer:
The cells need oxygen for metabolism, which creates carbon dioxide as a waste product. The carbon dioxide is absorbed from the cells by the blood plasma (some of it binds to hemoglobin too) and is transported back to the lungs in the bloodstream. There it leaves the body when we breathe out.

The correct answer is: oxygen and nutrients.
Ocean abiotic factors are non-living factors that influence an ocean ecosystem.
Nutrients are substances that ocean organism obtains from their environment in order to grow and live such as nitrogen, phosphorus, sulfur, carbon, iron, potassium, magnesium.
Oxygen is a necessary element required for respiration (most ocean organisms are aerobic), metabolism and other chemical reactions within the organism. Oxygen in the ocean is produced by algae and phytoplankton via photosynthesis.
whichever one comes first like the first step.
