Humus

forest species , hence their high adaptivecapacity 19 . These species are a carrier species and an engineer . They contain a significant biodiversity ( epiphytes , birds, insects, parasites and other symbiotes) and provide a low-acid, low-mineral soft humus that produces brown, neutral or even slightly alkaline brown soils 20 . Botanists distinguish two major categories of oaks 21 : oak deciduous whose leaves fall in autumn, sometimes spring ( red oak , turkey oak , downy oak , Pyrenean oak and oak );

Acid Rain is basically rain that has been made acidic by Sulfur DiOxide ( SO2 ) and other pollutants. Acid rain is formed by the release of ( SO2 ) and ( NO2 ) into the atmosphere. Then the chemicals are absorbed into the rainwater and create acid rain. Acid rain , mostly comes from the chemicals emitted into the air by coal fired power plants. Now there is a big push for clean coal and these power plants have mostly accomplished that. The power plants have scrubbers, covered in limestone that

Due to the extensive amounts of plastic and manure waste thrown into the environment without properly being composted and recycled, it is causing ecological damage, which is affecting humans and other species. Environment is the main home of mankind and species thus making it the most important aspect in life, without our ecology we wouldn’t be having oxygen, plants and trees. Everyone must give importance to wellness of our environment. Wellness of the environment is directly proportional to the

logy12 Biology Demonstrate understanding of adaptation of animals to their way of life Gas exchange – Process in which gas is oxygen exchanged for carbon dioxide THE WORM The worm lives underneath the ground in moist rich humus soil. The worm is Terrestrial- which means it is related to earths or its inhabitants, and is not restricted to moist environments as the worms internal lungs keep it moist. As worms are nocturnal they only are active at night Which gives them less chance to

A biological community is a discrete, useful and life maintaining environment . The natural system comprises of biotic and abiotic components in a living community if ecosystems are degraded it can lead to increased flooding due to the erosion of soil and lack of trees, rising of the sea levels due to the melting of the glaciers, caused by Global Warming.water shortage, food shortage (as the lands become barren and the oceans become fish less), loss of biodiversity as whole species of living things

How does the pH level of soil affects plant growth Did you know 16 million people in the world are vegetarian? Plants need soil to live, and we need plants to live. Most soils contains clay, silt, sand, stones, rocks, boulders, humus, and peat. Soil also has a pH level. “A pH is a measure of the hydrogen ion concentration of a solution.”Different climates have different soil pH. For example, soil in desert has a very basic soil pH. The pH of something can be measured using the pH scale. If it is

Most people know how school lunches work you come get your lunch eat then you throw it away, but most people don't know what happens to the food after you eat and how it should be handled. There are multiple ways to get rid of the food but, one of the ways to get rid of the food schools don't like it, and that way is to compost the food. It i being discussed why you must not compost the cafeteria food and i will show you why it should be composted. I think composting school cafeteria food is really

agricultural practices that can benefit the soil and earth. If people can find a way to cultivate the land without harming the soil, then it might be a good thing and restore nutrients to the soil. If nutrients can be restored back into the soil, then the humus layer will not deteriorate and the soil will be strong enough to defend itself against erosion. Thirdly, farmers can hold back on livestock grazing so that the vegetation of the area will not be completely consumed. If grazing is decreased, then vegetation

In the Edwards Plateau the estimated annual interception loss – that is, the proportion of precipitation that never reaches mineral soil – for a given site dominated by stoloniferous grass was 10.8% of annual precipitation, while a bunchgrass dominated site had an annual interception loss of 18.1%. Oak trees and the litter beneath the trees intercepted about 46% of annual precipitation (Thurow et al., 1987). This indicated that shifts in the kind or amount of vegetation affect interception. Vegetation

Antarctica is an unrivalled continent and well known for the extreme environmental conditions, as the temperature is lowest, high wind speeds, high UV-B radiations and isolated landmass on earth. Growth conditions for the organisms are extreme and plants exists with the physiological limits of survival over Antarctica. Antarctica having terrestrial biota comprising microorganisms, ichens, fungi, algae, bryophytes and invertebrates. Cryptogams are the major components of the Antarctic flora and their
