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.

Less than .1% of the energy in a food chain generally makes it from the sun to consumers

Elena-2011 [213]

This statement is true.

Reason:

Plants are capable of storing energy from the sun and with the help of that they produce their own food. And this energy is transformed to the animals as well as human being when they consume the food which was grown on the plants. But when they consume it they are only able to get 10% of the energy and the last consumers are able to get only about 1% of the energy.
