Unicellular organisms
Explanation:
Unicellular organisms typically respires faster to release energy.
Respiration is a gaseous exchange between cells and the environment. Here, oxygen is taken in by the cell and carbon dioxide is the by product of the metabolic process.
- Unicellular organisms will respire faster because they are at the lowest level of organisation.
- The cells are in direct contact with the environment.
- They do not require special set up to obtain and circulate oxygen in them.
- The waste of the metabolic process is also discarded easily and very fast.
- Organisms at lower levels of organisation typically have a faster rate of respiration.

The cytoskeleton provides energy to cilia
Explanation:
The motion of hair-like structures or axonemes called cilia or flagella are done through sliding movements of one another. This motion needs energy and motor protein molecules called dynein.
Dynein is a cytoskeletal motor protein present in the cytoskeleton and moves in the microtubules and converts the chemical energy in the ATP to mechanical energy to power the sliding and bending movements of cilia.
Apart from facilitating movement, cytoskeleton also contains other proteins which helps it to provide shape and support.
Hi,
Autotrophs are biotic factors.
