Plants give animals the food and shelter they need. Herbivores, which are plant eating animals, rely on plants to provide them with a regular source of food. They also provide shelter to may animals, both large and small.
Answer:
Different plants have different strategies for the dispersal of seeds. It dependents upon the environment in which they are growing. The three different ways of seed dispersal are:
1. Gravity: As, the fruits in the seeds gets ripen, they fall from the trees or plants because of the action of gravity acting on them. This mechanism is called as abscission. The seeds gets ejected or comes out of the fruit after degradation and decomposition of the fruit.
2. Wind and water: Wind and water are two agents which facilitates the transfer of seeds from one location to the other location.
3. Animals and birds: The animals and birds consume fruits along with seeds. They leave the seeds to different location, in the form of whole seed, partially consumed fruit or in the form of seed present in their biological waste.
