light, water, temperature and nutrients. all of These four elements affect the plant's growth hormones, making the plant grow more quickly or more slowly. Changing any of the four can cause the plant stress which stunts or changes growth, or improves growth
T<span>he cell requires oxygen, and eukaryotic cells are expensive to run. they require a lot of energy and nutrients, and oxygen is one such component. the oxygen is necessary for aerobic respiration, which allows the cell to do a lot, including evolve, proliferate, adopt new niches, habitats, biochemical habitats, sustain life in extreme conditions, and perhaps eventually co-operate with other cells and create multicellular life. Multicellular life is virtually impossible without aerobic respiration. </span>
No, this is false some invasive species help balance out populations but then again it may sway out of control again. Also, not all invasive species have a negative impact on the ecosystem.
