Three different species of plants were selected by scientists who wanted to document their methods of seed dispersal. The graphs below show the approximate number of seedlings found at various radii around the parent plant.
What are the correct methods of seed dispersal of each plant?
| Species 1 | Species 2 | Species 3 | |
| A | Water | Explosion | Animal |
| B | Wind | Animal | Water |
| C | Wind | Animal | Explosion |
| D | Explosion | Water | Animal |
A very tough question

C) Seeds which are dispersed by wind are usually carried to far off places due to their small size and light weight, e.g. , seeds of cotton and dandelion. similarly, seeds dispersed by water are also light and can easily float and carried to far off places by water, e.g. , seeds of coconut. dispersed by animals seeds of guava can be carried by human beings and animals to nearer as well as long distance from the parent plant. Explosive action of some seeds peas and balsam scatter away from the parent plant but it usually cannot enable the seeds to be dispersed far off places.
