Detailed explanation-1: -Two of the most fundamental means of seed dispersal are wind and water, these vectors carry light seeds to various places where they can germinate. Animals and birds also play a key role in the dispersal of seeds as they carry seeds away from their parent plant for germination.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Water dispersal The seeds float away from the parent plant. Mangrove trees live in estuaries. If a mangrove seed falls during low tide, it can begin to root in the soil. If the seeds fall in the water, they are carried away by the tide to grow somewhere else.
