Detailed explanation-1: -Seeds dispersed by water are found in light and buoyant fruits, while those dispersed by wind may have specialized wing-like appendages. Animals can disperse seeds by excreting or burying them; other fruits have structures, such as hooks, that attach themselves to animals’ fur.
Detailed explanation-2: -Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.
Detailed explanation-3: -One of the significant ways that animals disperse plant seeds is by eating and pooing them out. Certain plant species, including many trees, enclose their seeds inside fleshy edible fruits that are appealing to hungry animals. These fruit-loving animals are called frugivores.
Detailed explanation-4: -The seed of these plants catches on the fur of animals and are carried away to different places, far from their parent plants. Dates, rambutan, sea grapes, sea holly, tamarind, raspberry, sunflower, tomatoes are a few examples of plants whose seeds are dispersed by animals and birds.
