The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.
Answer:
Not good for such old age
Explanation:
Carbon 14's half-life is about 5,700 years. So, it cannot be used to date something more recent than that. Also, due to the decay, it cannot be used on items older than about 50,000 years.
Then youngest a sample from the precambrian era could be is about 541,000,000 years (541 millions), so it's WAY past the range of use of Carbon 14, since there wouldn't be any carbon 14 left in the sample to evaluate the age through C14's half-life cycle.
