Ppt Nutrient Cycles Powerpoint Presentation Free Download Id 6494708 Nutrient cycles. nutrient cycles. carbon, nitrogen and phosphorus cycles. nutrients. nutrients are chemicals that are required for plant and animal growth and other life processes nutrients are accumulated for short or long periods of time in earth’s atmosphere, oceans and land masses. 483 views • 25 slides. 2. carbon, oxygen and nitrogen cycles are gaseous nutrient cycles, with the atmosphere and oceans as main reservoirs. sedimentary nutrient cycles include sulfur and phosphorus, with soil, rocks and minerals as primary sources. 3. energy from the sun drives biogeochemical cycles and flows through ecosystems via photosynthesis, food chains,.

Nutrient cycles. nutrient requirements biogeochemical cycles rates of decomposition plant adaptations in low nutrient conditions. nutrient requirements for plant growth. taken up in gaseous form, oxygen (o 2 ), carbon co 2 , and from roots water (h 2 o). Nutrient cycles nitrogen and phosphorus why do we need nitrogen?? nitrogen is needed to make up dna and protein! in animals, proteins are vital for muscle function. – a free powerpoint ppt presentation (displayed as an html5 slide show) on powershow id: 43ea1c zdnjn. Nutrient cycling is never perfect i.e. always. losses from system. input and output (terrestrial systems) 23. terrestrial systems contd. inputs and outputs are small in comparison. to amounts held in biomass and recycled. 3. relatively 'tight' cycling is the norm.
