Anything containing <span> electricity </span> or magnetism. For example would be drinking water because that is the result of the electromagnetic force holding those hydrogen and oxygen atoms together.
Movement of Na+ and K+ in neurons are active transport during stimulation.
Answer:
For the photossynthesis there are requirement of cholorplast which is found on the surface of the plant leaves mostly that traps the light and convert light energy to the storage energy or glucose. Leave have larger surface area so the maximum amount of light can be traped for the photosyntheis by the cholorplast present in palisade cells.
Other than this leaves also helps in the gaseous exchange with stomata; small openings, by allowing carbon dioxide and oxygen into the leafe and outof the leave respectively. The veins helps in the transport of the gluscose and nutrition.
Assuming that you're referring to forest ecosystem, the two ecological benefits of this ecosystem are :
