Question

What is called dispersal by water birds and wind and animal?

Answer 1

Seed dispersal is the movement or transport of seeds away from the parent plant. Plants have very limited mobility and consequently rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living (biotic) vectors like birds.

Answer 2

Answer:

If all the seeds fall at the same place and grow into new plants there will be overcrowding. Then plants will not be able to grow as they won't get proper sunlight, water, minerals and space. So, to prevent overcrowding, competition for sunlight and nutrition seed dispersal is very necessary.
