D.Elements continuously cycle between the physical environment and living organisms.
Ecosystem is encompassing all the life on earth in the physical environment that supports it. An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system. <span> </span>
Cells don't grow very big because they have to be able to diffuse through material easily. Also, when cells are small and plentiful they are easy to replace when damaged.
Phytoplankton contribute positively in the oceanic ecosystem as they are a source of food for oceanic animals. Moreover, they remove carbondioxide from the carbon cycle and utilize it for the process of photosynthesis.
Answer:
The answer is B- 12
Explanation:
The glycolysis of one glucose molecule produces two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, ten (10) NADH molecules, and two (2) FADH2 molecules per glucose molecule. Therefore the total number of NADH + FADH2 molecules produced is 12.
