Detailed explanation-1: -If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
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: -Explanation: Seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living (biotic) vectors like birds.
Detailed explanation-4: -Seeds that disperse farther from the parent plant are more likely to survive and grow, leading to a forest with many species of trees, with individuals from the same species spaced widely apart.
