HORTICULTURE

Detailed explanation-1: -Succulent fruits attract animals because they are brightly coloured, juicy and nutritious. When eaten, the seed pass through animal’s faeces, which may be a long way from the parent plant. The faeces provides nutrients when the seeds germinate.

Detailed explanation-2: -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-3: -Plants, being stationary, require a mobile mode for seed dispersal. Modes for seed dispersal include self-projectile mechanisms, wind, water, and animals. Dispersal by animals falls into the category of plant-animal interactions, a subject of interest because of the reciprocal adaptations that can be observed.
