Answer:
A plant needs a few environmental factors to grow. Every plant is different, though. Some need a certain amount of shade and sunlight, and others need different amounts of water. Different plants grow in different climates as well. Genetically, if the seeds planted came from plants that typically grow taller or faster, then the seeds are likely to have the same trait, and vice versa. In addition, plants and crops can thrive from some bugs and animals, but others will just hurt the plant.
