Changes in Seasons
During our year we have what is called seasons. they are winter, spring, summer and fall. There are many changes that happen during the seasons.
Changes in Plants
In winter plants can look like they are dead because their leaves may be off, but they are only in a dormant state. This is like a plant hibernation.
In spring there is more rain and this causes the plants to bloom and the leaves on trees to grow.
During fall the trees may loose their leaves. Many people think that that is because the days are colder, but this is actually because the days are getting shorter, so there is less sunlight for them to make food.
In the summer, the weather is warm, the sun is shinning and their is more rain so fruit is produced.
Changes in Animals
Animals must adapt to seasonal changes. Some animals grow a thick winter coat of their hair or fut to stay warm. During the summer these animals shead their "coat" to be cooler. Some animals also change the color of their fur to their surroundings, for example the snowshoe hare is white in the winter and brown in the summer.
Animals also may begin to eat a lot during the summer in preparation for the colder winter seasons. These animals hibernate, which is a sleep like state. For the animals that did not adapt well to the season changes, these animals migrate, or move to a new more climate location.
Plants can be harmful too
Plants Change the Land
The water hyacinth is abeautiful flowering water plant, but because it is not a native to Florida, it can cause many animals and plants native to Florida to die off.
Kudzu is another invasive plant that was brought to areas of the USA. It was innocently used to cover bare hills inorder to keep the soil on the hills from washing away.
Plants can change the environment as much as the environment changes plants. Even grass effects the environment. Grass takes in carbon dioxide and releases oxygen, which we humans breath. Also plants have roots and those roots hold our soil from blowing and washing away.
Plants not only keep our soil in place, it can help make the soil better. The roots trap tiny pieces of rock and decaying plant matter which make the soil better.
