Must produce reproductively viable offspring. Plants attract animal pollenators with nutritional rewards supplemented by advertisement in the form of olfactory and visual cues. Regarding insects, the majority of insect Orders existed prior to the acendancy of flowering plants. However, the tremendous diversification within insect Orders was likely stimulated by the diversification of flowering plants. Many plants, especially certain trees, rely on wind for pollen distribution 2.
Result is animals carry seeds elsewhere, dispersing the plant.
