Animal: can be transported on the outside of the animal or via ingestion by animal. Gravity: causes heavier fruits to fall from the plant when ripe. Examples include passion fruit. Wind: can take on one of two primary forms: the seed can float on the breeze or can flutter to the ground. Examples include dandelion Water: can be transported by ocean currents over long distance. Examples include coconut
3
Improves the chances of the seeds being able to grow Ensure that the number of seeds available for predators to eat right below the parent plant is lesser
4
Separating of seeds: (reasons)reduce competition of water, nutrients, light and fight for resources. If seeds are crowded together they will grow upward in search of light.
5
Adult plants remain in the same spot for their entire lives, they rely on seed dispersal to transport their offspring throughout the environment. Seeds dispersal helps to increase the area over a particular type of plants which may be found.
6
Ensure that the number of seeds available for predators to eat is lesser
7
Seeds dispersal can avoid adverse environmental effects such as fire or drought, reach nutrient-rich microsites and survive longer than other seeds
