Summary#4:Cycles of life =)

There are Tree cycles in life and are Water cycle , Carbon cycle, Nitrogen cycle .

Water Cycle

The water cycle began in evaporation them continue with condensation , ect. this process don't ends it is called "recycle water " this is the most importance cycle .

The cycle of matter is continuos. How does This happen? An old, fallen tree is made wood, bark, and other dead tree tissue. That tissue holds all sorts of complex to be used by most other living things. They need to be broken down into simpler chemicals. This is the job of decomposers. They are organisms that recycle matter from dead organisms. Worn, crickets, cockroaches, bacteria, and fungi are decomposers. These organisms can break down dead wood and other dead plant parts into carbon dioxide and and ammonia. All living plants need carbon dioxide in order to make sugars. Ammonia is a simple  substances that contains the element nitrogen. Nitrogen is extremely important for plants. NO plant can live o grown without nitrogen. All organisms need nitrogen in order to make proteins. Nitogen is a chemical found in plant fertilizers. Fertilizers ae substances used to add mineals to the soil. Some fertilizers are natural. these ae decaying plants and animals, and animal wastes. Other fertilizers are made in factories. Both natural and artificial fertilizers, contain nitrogen.

Carbon cycle

One of the elements that make up all living things is carbon. Nature recycles carbon, and it is used by all organisms. The recycles of this important substance is called the carbon cycle.

Nitrogen Cycle

What do you need nitrogen for? When you eat meat, fish, cereal, or vegetables, you are taking in the nutrients that your body needs  to make  proteins. Proteins are parts of your muscles and many cell structures . Among other things proteins ae rich in the element nitrogen . You need nitrogen to make parts of your body, such as muscles, nerves, skin, bones, blood, and digestive juices. Nitrogen are 78 part of the Earth .
