Dispersal helps different species to increase their range of places, thereby helping to increase their population size in different regions. Dispersal also helps to avoid crowding of diseases of a single location as species move to different locations.
<h3>What is dispersal?</h3>
- Dispersal is the act of distributing things over a large area. It is when the individuals or seeds move from one site to their growing site.
- Dispersal can be active (move by oneself) or passive (require dispersers).
- Seed dispersal is the mechanism of transport of plant seeds to new sites for germination and the establishment of new individuals and colonies.
- This depends upon the effectiveness of the seed dispersers.
- Seed dispersal occurs by wind, water, animals, bats, explosions or gravity of the earth.
- Dispersal of seeds is very important for the survival of plant species.
- If the plants of same type grow too closely, they have to compete with each other 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.
