Mutated gene
A mistake by cellular machinery, or damage from an environmental agent such as radiation may produce a mutated gene which is a permanently altered segment of dna.
A gene mutation is a perpetual change in the DNA sequence that forms a gene which makes the sequence different from what is present in most people. Gene mutations can be classified into; hereditary mutation (changes inherited from parents) and somatic mutation (changes caused by environmental factors such as ultraviolet radiation from the sun).
It's because all living things need energy to do a specific thing for a much longer period of time. If chemical reactions undergo releasing energy, you wouldn't be able to function on something, and it would be for a much shorter period of time.

Answer:
Strictly speaking, species diversity is the number of different species in a particular area (species richness) weighted by some measure of abundance such as number of individuals or biomass. ... An ecosystem where all the species are represented by the same number of individuals has high species evenness.
