DENDROLOGY

Detailed explanation-1: -Wind, water, animals, explosion and human are considered generally as agents of seed dispersal. Whereas, sunlight doesn’t have any direct effect on the dispersion of seeds.

Detailed explanation-2: -Seed dispersal is the movement of seeds away from the mother plant for germination. This avoids competition of the seeds with the mother plant for air, water and minerals. It takes place by wind (e.g. dandelion), water (e.g. lotus), birds and animals (e.g. nuts) and human beings (e.g. sugarcane).
