<span>The cytoskeleton is a
structure found in the cytoplasm that is composed of a web of proteins. It is a
network composed of protein microfilaments, intermediate
filaments, and microtubules. They can be found in all living organisms and are
responsible for giving them their distinct cell shapes and coherence.
Aside from
providing the cell shape, the cytoskeleton is also responsible for cell
movement, organelle movement, and cell division.</span>
<span>It plays a crucial role in
cell division because they provide the movement of chromosomes to the daughter
nucleus. The absence of these protein filaments would result to different
abnormalities and diseases in the genes. </span>

Answer:
Nutrient cycle is a process of movement, reuse or recycling of nutrients in that particular environment. They are for both living and nonliving things, elements like carbon, oxygen are recycled through such cycles.
Nutrient cycle in an ecosystem involve:
- carbon cycle
- nitrogen cycle
- oxygen cycle
- phosphorus cycle
ATP (adenosine triphosphate)
