Editor's Notes
- BIOGEOCHEMICAL CYCLE- CAME FROM 3 BRANCHES OF SCIENCE BIOLOGY| GEOLOGY| AND CHEMISTRY When we say “cycle” it is a series of events that are regularly repeated in the same order. 3. Therefore, Biogeochemical cycles are named for the cycling of biological, geological and chemical elements through Earth and its atmosphere. 4. Biogeochemical cycles are a form of natural recycling that allows the continuous survival of ecosystems (hindi magwoworkout pag wala ang biochorva) 5. Most important types of BC are the following the 4(carbon, water, nitrogen oxygen cycle) are gaseous cycle while the other 2 ( phosphorus and sulfur cycle) are sedimentary cycle
- The CARBON is second most abundant in organisms, the first is water. CARBON is the primary element that made up human tissues. Human are 18% carbon It is necessary for plant. Used in photosynthesis (sunglight, water, carbon dioxide) All the life from unicellular to blue whale (the largest animal ever existed) is made of carbon. Carbon is needed in the atmosphere as well because it helps to keep the Earth warm. Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world.
- IPAEXPLAIN MO OR BASAHIN MO NA LANG CO2-CARBON DIOXIDE GREEN PLANTS PHOTOSYSNTHESIS (needed water, sunlight and CO2) Decay/decomposition - When plants and animals die they decay. When this happens, the carbon in their body will either be released into the atmosphere or stored in ground as fossil fuels. Respiration (breathing) - Every time you breathe you turn oxygen into carbon dioxide. This is true of every animal on Earth. Combustion (burning) - When plants, trees, or fossil fuels are burned, carbon is released into the atmosphere.
- 1.The water cycle or HYDROLOGIC CYCLE 2. Water is found throughout the biosphere, and is probably the most important substance needed to sustain lifeforms. Humans can survive for many weeks without the energy obtained by eating food, however, we would only last a few days without water. 3. The hydrosphere includes the atmosphere, land, surface water, and groundwater.
- 1. Precipitation, which is the falling of water in any form to earth; 2. evaporation or transpiration, which occurs either when water is heated and turns into water vapor or when plants use the water and give it off as water vapor, respectively; and 3. condensation, which occurs when water vapor cools and forms clouds. This process is then repeated over again. 4. infiltration, which is the process in which water is absorbed into the soil (it may also flow off the surface called surface run off); 5. IMPORTANCE: The cycling of water shapes our weather and climate, supports plant growth, and makes life itself possible. The water cycle is dominated by the oceans, where 96 percent of the water on Earth is found and where 86 percent of global evaporation occurs.
- Nitrogen is the most abundant element in our planet’s atmosphere. Approximately 78% of the atmosphere is comprised of this important element. Nitrogen is used in fertilizer to help plants grow faster. Nitrous oxide is a greenhouse gas. Too much of it can also cause acid rain. For Nitrogen to be used by different life forms on Earth, it must change into different states. Nitrogen in the atmosphere, or air, is N2. Other important states of nitrogen include Nitrates (N03), Nitrites (NO2), and Ammonium (NH4).
- Fixation - Fixation is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium. Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can then absorb. Assimilation - This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. Ammonification - This is part of the decaying process. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle. Denitrification - Extra nitrogen in the soil gets put back out into the air. There are special bacteria that perform this task as well.
- Oxygen is an important element to life on Earth. It is the most common element of the human body. It makes up about 65% of the mass of the human body. Most of this is in the form of water (H2O). Oxygen also makes up about 30% of the Earth and 20% of the atmosphere.
- The oxygen cycle is interconnected with the carbon cycle. In the simple example of the oxygen cycle shown below, you can see how oxygen is used and cycled by plants and animals. Plants are the main creators of oxygen in the atmosphere through the process of photosynthesis. Here the tree uses sunlight and carbon dioxide to produce energy and releases oxygen. The giraffe breathes in the oxygen and then breathes out carbon dioxide. The plant can then use this carbon dioxide and the cycle is complete.
- Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion , located in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Phosphorus is an important element for all forms of life. As phosphate (PO4), it makes up an important part of the structural framework that holds DNA and RNA together The phosphorus cycle differs from the other major biogeochemical cycles in that it does not include a gas phase
- Although sulfur is primarily found in sedimentary rocks or sea water, it is particularly important to living things because it is a component of many proteins. Sulfur (S), the tenth most abundant element in the universe, is a brittle, yellow, tasteless, and odorless non-metallic element. It comprises many vitamins, proteins, and hormones that play critical roles in both climate and in the health of various ecosystems. The majority of the Earth’s sulfur is stored underground in rocks and minerals, including as sulfate salts buried deep within ocean sediments. The sulfur cycle resembles that of nitrogen in several respects, for example the short‐term movements of both elements is through the atmosphere as a result of the metabolism of bacteria. The gases move rapidly in a closed cycle from the air to the soil and back. There are several subcycles: 1.) a long, deep time cycle of weathering, erosion, deposition, 2.) a predominately atmospheric cycle where bacteria metabolize dead organic matter and release sulfur to the atmosphere where it has a short residence time before being washed back to the soil by precipitation, 3.) a marine cycle where evaporation of sea spray releases sulfur to the atmosphere temporarily and from where it falls back into the sea, and 4.) a soil–plant cycle where organic sulfur in manure or other fertilizer is used to sustain soil microbes and plants.
