The steady influx of oxygen maintains a habitable biosphere. ]]> 2018-02-07 12:34:25 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229059823 koreena_nicole https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229060839 The process that purifies water into forms that the environment can use. The majority of the world is water and people need clean water to survive.  The water cycle begins with evaporation which changes the water molecules to water vapor. then condensation where the water vapor becomes a cloud. Then precipitation where the water vapor becomes liquid water and falls back down to earth. Finally the water runs off into lakes, ponds, and oceans. ]]> 2018-02-07 12:37:59 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229060839 koreena_nicole https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229061091 2018-02-07 12:38:39 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229061091 koreena_nicole https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229063454 Cycle which nitrogen is converted into different forms as it circulated in air, water, and land.  atmospheric nitrogen goes into the soil and is fixed by bacteria and turns it into ammonium through the process of ammonification. Bacteria then nitrofies the nitrogen through nitrification which plants then can use. when animals die decomposers break down there nitrogen into ammonium. the nitrates are turned into atmospheric nitrogen by denitrification. It is important because nitrogen is essential for growth and reproduction in plants and animals. ]]> 2018-02-07 12:47:06 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229063454 koreena_nicole https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229067001 2018-02-07 12:57:23 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229067001 koreena_nicole https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229067034 2018-02-07 12:57:31 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229067034 koreena_nicole https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229067627 The movement of phosphorus through our biosphere. It is used in plant growth which is necessary for ecosystem sustainability. Plants absorb phosphorus from the soil. Animals eat the plants. The animals and plants die and are broken down to put the phosphorus back into the soil. Phosphorus erodes due to runoff making the soil less compatible for plants. ]]> 2018-02-07 12:59:30 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229067627 koreena_nicole https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229068971 2018-02-07 13:04:21 UTC https://padlet.com/koreena_nicole/o1rsmc7avghi/wish/229068971
