It’s important because it helps maintain the soil especially if the soil has low organic matter.
1) Diffusion and osmosis
the diffusion of water through a semipermeable membrane is osmosis and the movement of particles from regions of higher density to regions of lower density is diffusion
2)The passive transport does not require energy and the active transport does ,this is what makes them different
3)Endocytosis is a process for moving items that are outside of the cell into the cytoplasm of the cell. Exocytosis is a process for moving items from the cytoplasm of the cell to the outside.
"Inorganic material" is that matter which helps plant to complete the cycle and it's provided by decomposers 'cause they break down dead matters into it.
Hope this helps!
I believe the answer you are looking for is they are all body systems found in the human body, or organ systems.
Engulfing is what happens during endocytosis, a form of active transport that takes large molecules into the cell. During this process, the molecule is trapped inside a newly-formed vacuole. Hope this helps! :)
