humans and animals need oxygen to live. What is the contribution of candido bartolome to gymnastics? When forest cover is removed, rainfall hits the soil much harder and this can lead to loss of topsoil in a process called soil erosion. Nutrients are usually dissolved in rain and when it does rain nutrients are 'rained' into the soil. Humans have cut down forests for many reasons and have built their economies on exploiting natural resources. Oxygen cycle, circulation of oxygen in various forms through nature. Carbon dioxide concentrations have been rising over the past century and this is leading to permanent and potentially damaging alterations to the earth’s climate system – a process called climate change.

When did organ music become associated with baseball? Trees and plants, in general, produce energy for growth using a process known as photosynthesis. In many tropical regions, forests protect the sometimes violent tropical storms from hitting the ground. Using light, water and carbon dioxide, a plant produces energy in the form of sugar and releases oxygen into the air. Free in the air and dissolved in water, oxygen is second only to nitrogen in abundance among uncombined elements in the atmosphere. Much of our oxygen comes from trees so if we cut down the trees then their will be more carbon dioxide in the air instead of the needed amount of oxygen. When trees are removed, soil levels of phosphorus are diminished greatly and this nutrient is vital for plant growth. So when trees are lost, less water evaporates from the soil, more water is lost in run-off and so rainfall can be reduced. This oxygen is essential for all the living beings on earth. Trees convert carbon dioxide into oxygen using photosynthesis. How do you put grass into a personification? How will understanding of attitudes and predisposition enhance teaching?

How does deforestatation affect the oxygen cycle? Photosynthesis and deforestation are closely related because they both affect the way that we, as humans live our lives.
