Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.
<h3>Mutation</h3>
This refers to a sudden change to the DNA sequence of living organisms.
When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.
For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.
In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.

D.) none of the above is human induced cause of extinction
1. Respiration-process by which plants release CO, while they break down the sugar
2. Animals eat plants- They break down sugars and starches by a process of metabolism and the products are energy water, and CO2 molecules.
3. Decomposition-when plants die, their parts (wood, leaves) decay bringing the carbon into the ground
4. Root respiration- respiration that occurs in roots, adds to soil respiration (the amount of CO2 produced through root respiration is determined by the root biomass ).
