Which plants rely on animals to disperse their seeds?

Plants are a very important part of the ecological environment. At present, the call to protect the environment is growing louder, the area of greenery is also growing larger, and very many people are planting all kinds of plants. So what relies on animals to disperse seeds?

1. What relies on animals to disperse seeds?

Small birds or other animals eat the seeds, and because they cannot digest them, the seeds are excreted with their droppings and dispersed in all directions. Dispersal by small squirrels happens when animals carry seeds as they move about. Animals with fur pick up cocklebur seeds on their bodies as they walk, and in this way the seeds are dispersed. Representative plants include cherry, pine cones, cocklebur, and so on.

2. The main ways plants disperse their seeds

1. Wind dispersal: plants dispersed by wind generally grow appendages shaped like wings or feathers; when the wind rises, these plants ride the wind and travel far to grow and reproduce. Plants that use this method of dispersal include dandelion, poplar, willow, elm and maple, and so on.

2. Water dispersal: when the coconut palm that grows by the sea matures, it falls by the shore, and the coconut drifts with the sea currents to other islands and grows there; after the fruit of the water lily matures, it sinks into the water, and once the fruit skin rots, the seeds wrapped in the sponge-like outer seed coat float up and drift to other places. According to statistics, there are more than 100 kinds of seeds worldwide that are dispersed by ocean currents alone. Representative plants include coconut, water lily, and so on.

3. Mechanical dispersal: the fruit of the garden balsam bursts open and flings the seeds in all directions; this is the method of mechanical dispersal, and many leguminous plants also disperse their seeds mechanically. Representative plants include pea and garden balsam.

4. Dispersal by people: when we eat fruit, we throw away the cores, and the seeds inside them sprout and grow. Representative plants include apple and pear.

There are very many ways in which plants disperse their seeds, and I hope this can help everyone understand how plants grow and spread.
