Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What might happen if seeds aren’t dispersed far enough?
A
there is competition with the parent plant for light
B
there is competition with the parent plant for carbon dioxide
C
the parent plant and the new plant both have plenty of nutrients
D
there is not competition between the plants for air
Explanation: 

Detailed explanation-1: -If seeds are not dispersed, all the seeds would fall near the parent tree. This will prevent those seeds from getting enough sunlight, air and water. As a result, most of the seeds would fail to germinate.

Detailed explanation-2: -Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete 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.

Detailed explanation-3: -New plants grow near the parent plant because all the seeds fall under the parent plant.

Detailed explanation-4: -Seeds that are spread far from the parent plant avoid competition with their relatives for resources and have the opportunity to colonize new areas. Both fruits and seeds have a variety of adaptations for different types of dispersal.

Detailed explanation-5: -If seed dispersal did not take place then the seeds will germinate right next to the original plant. The seed and the plant will compete for sunlight and water. Resulting for the plants getting less than needed sun light and water. Thus this will result in dying of the plant.
