Answer:
Seed dispersal can be advantageous (1) in escape from density-or distance-dependent seed and seedling mortality, (2) by colonization of suitable sites unpredictable in space and time, and (3) by directed dispersal to particular sites with a relatively high probability of survival.

Explanation:
- The survival of plant species depends heavily on seed dispersal.
- Plants must compete for light, water, and nutrients from the soil if they are grown too tightly together.
- Plants can spread out across a large area thanks to seed dispersal and avoid competing with one another for the same nutrients.
- There are numerous ways to spread seeds. Some plants have fruit that contains their seeds (such as apples or oranges).
- Animals consume these fruits, including the seeds, and when they defecate, the seeds are released into the environment.
- Some fruits, like a floating coconut, can be transported by water.
- Some seeds feature tiny hooks that can cling to the hairy coat of an animal.
