Question

How can animals disperse seeds?

Answer 1

Hint: The transfer or spread of seeds away from the parent plant is known as seed dispersal. The seeds of the plants are dispersed through various agents or vectors like wind, animals, water etc. The seeds adopt several modifications with respect to the agents for their dispersal.

Complete answer:
To solve this question, we must know about the dispersion of seeds by animals.
The dispersal of seeds by the animals is called zoochory. This form of seed dispersal is the most common and rapid form of seed migration. It is very useful for the spread of invasive species.

The plants which are adapted for the dispersal by the animals. The seeds which are dispersed by animals can have adhesive mucus, hooks or spines which stick to the animal hides. Example Xanthium.

Certain seeds of the plants are embedded inside fleshy fruit which is eaten by animals like squirrel, monkeys. This help in dispersing seeds from one part to another.
Several seeds are dispersed by the birds. The seeds adhere to the feathers or are swallowed and dispersed through their faeces.

Some seeds are dispersed by the help of insects and bees. These insects suck the nectar of the flowers which in turn help in seed dispersal. The seeds which are dispersed by insects are small and stick or hairy which adheres to the body and consequently get dispersed.

Note: Seeds are the reproductive part of the plant which germinates into a new plant under favourable conditions. Seed dispersal plays an important role in maintaining the species biodiversity. The seed dispersal away from the parent increases the chances of survival of seed away from the parent plant.
