Biotic dispersal refers to the movement of living organisms, such as plants and animals, from one location to another. This process can occur through various means, including the actions of animals that eat fruits and later excrete the seeds in different areas, or through wind and water carrying seeds to new environments. This type of dispersal is crucial for the survival and spread of species, as it helps maintain genetic diversity and allows organisms to colonize new habitats. Examples of biotic dispersal include birds spreading berry seeds and insects transporting pollen between flowers.
