Plants and animals could be bred by humans to be later consumed or utilized by humans in some way. For example, agricultural farming for food and clothing; breeding, raising, and then slaughtering animals for food and clothing; growing forests to eventually cut them for wood; or breeding animals and plants and experimenting on them in laboratories.
