Ecological Cycles
Vocabulary words
Ammonification
Ammonification: Bacteria decomposers break down amino acids from dead animals and wastes into nitrogen ammonium.
Ammonium
Ammonium •Form of nitrogen contained in fertilizer•generated in soil by breakdown of organic matter
Atmosphere
Atmosphere - layer of gasses around the earth
Carbon
carbon - A non-metallic element found in coal, petroleum and natural gas. Major component of life.
Carbon Cycle
Carbon cycle - Circulation of carbon through ecosystems
Cellular respiration
Cellular respiration Process by which organisms create energy from sugar
Glucose+ Oxygenà CO2+ H20+ Energy (ATP)
Condensation
Condensation This is where warm and cold air collide and form ice crystals that condense and form droplets of water.
Creates clouds in the air or fog on the ground.
Condense
condense -to change from a gas to a liquid
Decomposition
Decomposition - breakdown of matter by bacteria and fungi
Denitrification
Denitrification converts nitrates (NO3) in the soil to atmospheric nitrogen (N2) replenishing the atmosphere.
- removal of nitrogen or nitrogen compounds –Conversion of nitrogen to gaseous form
Evaporate
Evaporate -to change from a liquid to a gas
Evaporation
Evaporation - This is a process where the water is heated and turned into a water vapor. The sun is the main heat source for this process.
Fossil Fuels
Fossil fuels - Carbon-rich fuel from ancient animals and plants
examples: coal, gas, oil
Nitrates
Nitrates - different form of nitrogen•Found in plant nutrient and fertilizer •Animal feed, manures, and sewage Nitrification:
Nitrification
Nitrification - Nitrifying bacteria in the ground first combine ammonia with oxygen to form nitrites. Then another group of nitrifying bacteria convert nitrites to nitrates which green plants can absorb and use!
Nitrogen
nitrogen -Nitrogen is a non-metal, gaseous element
Nitrogen Fixation
Nitrogen Fixation - is when the nitrogen gets “fixed” and combines with oxygen or hydrogen
Photosynthesis
Photosynthesis -
Process by which plants make sugarEnergy (sun)+ Water+ Carbon dioxide Carbohydrates+ Oxygen
Precipitation
Precipitation -When water droplets in clouds become to heavy and begin to fall
Precipitation can be rain, hail, sleet or snow depending on the temperature and wind conditions
Respiration and decay -: •Mechanisms in which animal life and bacteria consume oxygen and release carbon dioxide
Percolation
percolation - When water seeps through the soil and ends up in the water table. It then flows into the streams, lakes, oceans, and other bodies of water. The process is then repeated again and again.
Transpiration
Transpiration -the process by which plants lose water through the stomata of their leaves
Weathering
Weathering - Physical and chemical process in which solid rock exposed at earths surface is changed to separate solid particles and dissolved materials
