Tree ProductsEaten Any Wood Today? You may have! And you probably brushed your teeth with it. Chances are you even dressed with wood. Skeptical? Here are just a few: Fruits and Nuts Fruit from trees such as apples and peaches, as well as nuts from trees such as walnuts, are all favorite products grown on trees.
Bandage Strips Tree gum, sap extracted from trees, makes the adhesive on bandage strips stick to your skin. Baseball Bats The white ash tree is a hardwood that is used to make baseball bats—including, of course, Kentucky’s own Louisville Slugger! Candles Tree gum can be used to make candles. Clothing Cellulose is used to produce rayon and acetate, which can be used to make a vast array of clothing such as ties, shirts, dresses, and suits. Combs Wood pulp and cellulose can be used to make plastics for items such as hair combs. Cough Syrup Cellulose products, used for their even-flowing consistency, often thicken cough syrups and other liquid oral medicines.
Mollisols home. Mollisols (from Latin mollis, "soft") are the soils of grassland ecosystems. They are characterized by a thick, dark surface horizon. This fertile surface horizon, known as a mollic epipedon, results from the long-term addition of organic materials derived from plant roots. Mollisols primarily occur in the middle latitudes and are extensive in prairie regions such as the Great Plains of the US.
Globally, they occupy ~7.0% of the ice-free land area. In the US, they are the most extensive soil order, accounting for ~21.5% of the land area. Mollisols are among some of the most important and productive agricultural soils in the world and are extensively used for this purpose. Mollisols are divided into 8 suborders: Albolls, Aquolls, Rendolls, Gelolls, Cryolls, Xerolls, Ustolls, and Udolls. USA Soil Survey. Soil Conservation. Net Primary Productivity : Global Maps. Download a Quicktime animation of this dataset (5 MB) Plants capture and store solar energy through photosynthesis.
During photosynthesis, living plants convert carbon dioxide in the air into sugar molecules they use for food. In the process of making their own food, plants also provide the oxygen we need to breathe. Thus, plants provide the energy and air required by most life forms on Earth. Plant productivity also plays a major role in the global carbon cycle by absorbing some of the carbon dioxide released when people burn coal, oil, and other fossil fuels. The carbon plants absorb becomes part of leaves, roots, stalks or tree trunks, and ultimately, the soil. The maps above show one way to monitor the carbon “metabolism” of Earth’s vegetation.
In mid-latitudes, productivity is obviously tied to seasonal change, with productivity peaking in each hemisphere’s summer.
