NEET BIOLOGY

Detailed explanation-1: -Seed dispersal is likely to have several benefits for different plant species. Seed survival is often higher away from the parent plant. This higher survival may result from the actions of density-dependent seed and seedling predators and pathogens, which often target the high concentrations of seeds beneath adults.

Detailed explanation-2: -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.

Detailed explanation-3: -Dispersal of seeds is very important for the survival of plant species. 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-4: -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.
