1. Pollination: Many plants rely on animals, like insects, birds, and bats, to transfer pollen between flowers, enabling fertilization and the production of seeds. This is crucial for the plant to reproduce and create new generations.

2. Seed dispersal: Animals can help plants disperse their seeds to new locations. This can be done through:

* Eating fruits and dropping seeds: Animals like birds and mammals eat fruits, digest the fleshy part, and excrete the seeds in their droppings, often far from the parent plant.

* Carrying seeds on fur or feathers: Some seeds have hooks or barbs that attach to animal fur or feathers, allowing them to be transported to new areas.

These are just two examples of how plants depend on animals for their survival and spread.
