The limitations of cell size are:
1) Surface area to volume ratio
2) Nucleo cytoplasmic ratio
3) Fragility of cell membrane
What are the cause of limitations on cell size?
The need for a surface area of sufficient area to allow the cells function→.
→If the surface area of cell increase volume increase to the cube of the linear increase.
→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.
Examples are muscle cells.

Answer:
A. Phytoplankton
Explanation:
They as producers contribute the most. Others do too, but not as much.
We would all die, because:
Without oceans; no water.
Without Oceans; no rainforest.
Without Oceans; fish.
Without Oceans: no rain.
We need water to survive, we need fish to eat, we need rain because for many places on earth that is all the water they get. Without the Ocean, we probably wouldn't have the glaciers, which keep the whole world cool, the Navy, Marine Corps, Marine Biologists wouldn't have jobs. We would all die without the Ocea.

In photosynthesis, <u>light</u> energy is transformed <u>chemical</u> energy <u>carbon</u> <u>dioxide</u> gas is released. In cellular respiration, <u>a glucose molecule</u> is broken down and <u>carbon dioxide</u> gas is released.
Explanation: Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
