Explanation:
The quantity of energy decreases down each trophic level as only 10% of the energy at the upper level is transferred to the next level, the remaining 90% is lost as heat during metabolic process. Through the energy pyramid we can explain how energy is lost at each trophic level, the number of consumer at each trophic level that will benefit from the transfer of energy depends on the size and quality of the energy from the autotrophs
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

second one is cytolysis meaning cell bursting
not sure what the third one is though but I hope this help. :)
