The nitrogen cycle is the system by which nitrogen is converted into different chemical forms, some usable to humans and animals and some not, as it circulates among the atmosphere, the land and the oceans. Encyclopaedia Britannica/Getty Images/HowStuffWorks Living things require nitrogen for ...
In nature, the nitrogen, phosphorous and potassium often come from the decay of plants that have died. In the case of nitrogen, the recycling of nitrogen from dead to living plants is often the only source of nitrogen in the soil. To make plants grow faster, what you need to do is ...
What are the four (4) elements that make up most of living matter? What effect do humans have on the environment? What is deforestation and what parts of the world are experiencing the greatest forest losses? What are the reservoirs for carbon, nitrogen, and phosphorous?
Why do all organisms require nitrogen? What makes a resource nonrenewable? What drives atmospheric circulation? What are the unique properties of water that make it so critical to life? How does carbon exist in the hydrosphere? What processes shape Earth's surface, and how does the atmosphere ...
Although many students assume breathing is necessary for life, this is not a characteristic of living things. Many bacteria are anaerobic, meaning they do not need oxygen to survive, but still are considered living things. Thus, although humans specifically must breathe to stay alive, this is ...
Anytime you do yard chores, collect the debris in a bucket and dump it into the compost bin. This forms the "brown layer," which provides lots of the nitrogen necessary for the composting process. Word to the wise: Weeds will technically break down to become compost, but they are tough...
as anyone who's seen a morgue locker scene in a police procedural no doubt knows. The field of cryonics has taken this idea further by devising methods to replace a recently dead person's blood with a protective chemical cocktail and freeze it in liquid nitrogen for potential revival at som...
To start out, you need to go for what is best for YOU even if there would be some negative consequences. You can't be happy unless you make decisions that are right for you. If you do not make your own decisions and make decisions that will benefit you, your life would be a big ...
Changes in any one of the 3 capitals has consequences for the other two. There’s a distinction here that we’ll need later; that between stocks, flows, and drivers. A stock is the value of a capital at a given point in time. A flow is its rate of change with time. Drivers are ...
Researchers have found that processing meats can result in the formation of carcinogenic chemicals. The smoking process, for example, may lead to the formation of cancer-causing compounds called polycyclic aromatic hydrocarbons. Also, processing meat often involves using nitrogen-based preservatives to pr...
