The cycles of life and surviviny in ecosystem.

Cycles of Life

Organism require certain thengs do stay aline



Water cycle:
The process of naturally recycling water on earth is called water cycle. The water cycle begins with evaporation, condensation, precipitation, Then goes to runoff and the it callects. Evaporation is the heat from the sun that is obsorbed by oceans, seas, lakes, streams, pond puddles and even devi the water evaporate and riseinto the air. Condesation occur when erough water vapor condenses into tiny water from vapor to tiniy ice arystal. Precepitation occur when the condensated water fall do earthm's surface as rain, snow or hail, then it goes to the runoff that is when water flows dounhill bacross the surface instead and plants remone water from the soil and finally occur collevtions that is when water flows into streams, linkes and rivers.

    

Carbon Cycle:


The recyaling of this important substance is called carbon cycle. Planets take in carban dioxide and give off oxygen, which animals use. Amimals eat plant sugars, starches proteins and other substances. The carbon in these substances is used by animals to make their oun body chemicals, the it goes to the soil that produce oil. Car exhaust and death, decy, storage releases the carbon compounds in their bodis and turned ento carbon dioxide by decomposers. During photasynthesis plants use the carbon from carbon dioxide.

   


The Nitrogen Cycle:

Thae way nitrogen mones between the air, soil,plants,and animal is nitrogen cycle.
plants absorb nitrates dissolved in water through their roots, them used by plants to make proteins.Animals eats plants proteins, or they eat other animals that eat plants proteins,anim,als wates contain nitrogen compounds.denitrifijing bacteria turn nitrates back into nitrogen gas.Air is madeup about 78% nitrogen gas.
Nitrogen -fixing Bacteria turn nitrogen gas in the air to nitrogen contaiming subtances that plants use to make their proteins.
decomposer break doun the plants proteins. Soil bacteria change ammonia into nutrites.
Bacteria use nitrogen from air to amke nitrogen containing substances called nutrites.
