According to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.
<h3>What is photosynthesis?</h3>
It is the process of obtaining energy from plants, algae and certain bacteria to synthesize organic substances from other inorganic ones.
This metabolic process carried out by some cells of autotrophic organisms is essential for life since, starting from light and inorganic matter, it manages to synthesize organic matter and allows carbon dioxide (CO2) to be fixed from the atmosphere and oxygen to be released.
Therefore, we can conclude that according to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.

In order to add one gram of mass, the whale must consume a sufficient amount of energy. The energy transferred to the fourth trophic level is 0.1⁴ = 0.0001
We divide the mass to be gained by the energy obtained per unit mass, to find the total mass to be eaten:
1 / 0.0001 = 10,000 grams of phytoplankton must be consumed to add one gram of mass.
