OBJECTIVE FORESTRY

Detailed explanation-1: -Dispersal may occur by a number of different means, including gravity (basically, a simple means of dispersal involving the seed falling and potentially rolling downslope a short distance), wind, water, animals, and ballistic dispersal (adaptations that launch seeds from the fruit).

Detailed explanation-2: -Animals help in pollination and seed dispersal. Animals disperse seeds by carryng them on their body or by eating the fruit of a plant and disposing the seeds at some other location as they move.
