Question

Complete the following table (Carefully study the carbon, oxygen and nitrogen cycle)
Bio-geo-chemical cycles
1. Carbon cycle
2. Oxygen cycle
3. Nitrogen cycle
write biotic process and abiotic process​

Answer 1

Answer:

Biotic processes contain or involve living components while abiotic processes involve non living components.

Answer 2

carbon cycle : the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

oxygen cycle: Definition of oxygen cycle. : the cycle whereby atmospheric oxygen is converted to carbon dioxide in animal respiration and regenerated by green plants in photosynthesis.

Oxygen helps the body's cells function normally. The cycle of carbon dioxide and oxygen on Earth is dependent on plants and animals. Plants provide the oxygen that animals and other living things need to survive. Animals and other living things provide the carbon dioxide that plants need to make their own food.

nitrogen cycle:Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.
