DENDROLOGY

Detailed explanation-1: -Animals help in pollination and seed dispersal. Animals disperse seeds by carryng them on their body or by eating the fruit of a plant and disposing the seeds at some other location as they move.

Detailed explanation-2: -Birds and animals eat fleshy fruits and disperse the seeds to faraway places through their droppings. Examples:Watermelon, Lichi, Guava, and Mango. Some seeds have hooks on their outer surface, which allow them to stick to the animal fur, and in this way, they are carried to different places.

Detailed explanation-3: -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.
