What? Seed dispersal by animals.

Plants are a very important part of the ecological environment. At present, the voice of protecting the environment is getting louder and louder, and the area of greening is getting bigger and bigger. There are many people planting various plants. So what depends on animals to spread seeds?

What is seed dispersal by animals?

By birds or other animals to eat seeds into the stomach, because digestion can not be lost, they are discharged with feces spread in all directions. Squirrel dispersal is the dispersal of seeds carried by animals. Furry animals carry cocklebur seeds with them as they walk, thus spreading them. Representative plants are cherry, pine cone, cocklebur and so on.

2. Main ways of plant seed dispersal

1. Wind propagation: Plants that are spread by wind generally grow appendages that look like wings or feathers. When the wind rises, these plants will catch the wind and grow and reproduce in the distance. Use this way to spread dandelion, poplar, willow, Yu tree and maple, etc.

2. Spread by water: Coconut trees growing on the seashore wait until they mature and fall to the sea. Coconut trees drift to other islands with the sea. Where they grow, the fruits of water lilies mature and sink into the water. After the pericarp decays, the seeds of sponge-like exocarp will float and float to other places. According to statistics, there are more than 100 kinds of seeds spread by ocean currents all over the world. Representative plants include coconut, water lily, etc.

3. Mechanical dispersal: The fruit of balsamina will crack and bounce the seeds in all directions. This is the method of mechanical dispersal. There are many legumes that use mechanical dispersal of seeds. Representative plants are peas, balsam.

4. Spread by people: We eat fruit, the core will be thrown away by us, and the seeds inside will sprout and grow. Representative plants include apples and pears.

Plants spread seeds in many ways, I hope to help you understand the growth and spread of plants.
