  2. Nutrient Cycling . The nutrient cycle is a concept that PRODUCERS algoe, lichens ad green plamts describes how nutrients move from the physical environment to the living organisms, and subsequently recycled back to the physical environment. toten oler and mineral salts SOIL humus and minerols CONSUMERS dit Among the most important as nutrient cycles are the carbon nutrient cycle and the nitrogen nutrient cycle. decongosition die . Both of these cycles make up an DECOMPOSERS fungi and bacteria essential part of the overall soil nutrient cycle Nutrient cycdling


  3. Types of Nutrient Cycle Based on the replacement period a nutrient cycle is referred to as Perfect or Imperfect cycle. A perfect nutrient cycle is one in which nutrients are replaced as fast as they are utilised. In contrast sedimentary cycles are considered relatively imperfect, as some nutrients are lost from the cycle and get locked into sediments and so become unavailable for immediate cycling. Water Cycle (Hydrologic) .The hydrologic cycle is the continuous circulation of water in the Earth- atmosphere system which is driven by solar energy. Water on our planet is stored in major reservoirs like atmosphere, oceans, lakes, rivers, soils, glaciers, snowfields, and groundwater


  4. Water moves from one reservoir to another by the processes of evaporation, transpiration, condensation, precipitation, deposition, runoff, infiltration, and groundwater flow. Condensation Precigitation Evaporatien Water Cycle


  5. The Carbon Cycle Carbon from the atmosphere moves to green plants by the process of photosynthesis, and Photosynthesis then to animals. By process of respiration and decomposition of dead organic matter itmaita returns back to atmosphere. It is usually as E short term cycle. Fossil fuels are burned the carbon stored in them is released back into the atmosphere as carbon-dioxide Respiration Food Nutrients Organic dead organic material Waste materials Biodegradation Biodegradaton COy Carbon Cycle
