All cells are enclosed by a plasma membrane that is similar in structure and function. Cells have outer plasma membrane that regulates that is not only what enter in the cell.
Prokaryotes and eukaryotes both cells possess internal membrane that encase their organelles and control the exchange of essential cell components. The endoplasmic reticulum which has the structure similar to that plasma membrane which also considered as the cell membrane.
Yes plasma membrane and cell membrane are same , both are biological membrane which separate the interior of cell from the cells's extracellular space.The cell membrane is the security guard because the membrane controls what goes in and out of a cell like a security guard which control goes in and out of the gate.

Answer:
All
Explanation:
You would need carbon dioxide to be able to sustain life forms such as plants, warm enough temperatures to allow the development of animals, (because they cannot be frozen), they would, of course, need oxygen to allow anyone to breathe, and finally liquid water to sustain healthy life, because we must hydrate that is necessary for survival.

Explanation:
The abiotic factors help to circulate or transport the carbon element and its compounds in the ecosystem.
Abiotic factors are simply the non living parts of an ecosystem, such as wind, water, the rocks, volcanic eruption, sunlight etc.
An ecosystem is simply an interaction between the living organisms (biotic factors) and the non-living organisms in a habitat.
Therefore in a marine ecosystem abiotic factors such as wind and the water flow help to cycle the carbon which a vital element for the survival of the biotic factors in the ecosystem.
