The surface area to the volume ratio gets smaller as the cell gets larger. If the cell grows beyond a certain limit not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
Hope that helps
Answer:
Plant to animal to atmosphere.
Explanation:
- The carbon cycle describes the recycling of carbon from and back to the atmosphere.
- Plants utilize the carbondioxide present in the atmosphere to produce carbohydrates in the presence of light through the process of photosynthesis.
- When plants are consumed by animals, the carbon becomes a part of the animal.
- Animals break down glucose molecules into energy (ATP), releasing water and carbondioxide in a process called cellular respiration.
- This carbondioxide, as it is useless for animal cells, is released back into the atmosphere through gaseous exchange in the lungs.
