No.
Living things can only take part in chemical reactions using various forms of energy, and these only change the way chemical elements are bonded together, not the elements themselves.
yes by mold and other things
No. Melting does not change one element into another.
to make one element a different element, all you need to do is have a different number of protons
Early microbes did not significantly change Earth's atmosphere or climate because they did not produce enough oxygen as a byproduct of their metabolism to have a large-scale impact on the environment.
Oxygen combined with one other element is an oxide.
That would be radioactive decay.
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
"Substance" is too fuzzy a word. Chemical reactions can change materials into other compounds, for example shiny iron into rust (Fe2O3). But it cannot change an element into another element. A nuclear reaction can do that, for example uranium into plutonium.
The changing of one element into another, called transmutation, involves a change in the nucleus of the atom. And the number of protons in the nucleus must change for one element to become another one. It is the number of protons in the nucleus of an atom that determines what element that atom is, and only a change in the proton count will herald the change of one element into another. The neutron count may or may not change in transmutation, but be assured that the number of protons will change.
Microbes are organisms that are composed of only one solitary cell or a cell which lives in a colony with other cells. Thermophilic microbes are organisms that prefer to live in areas with a temperature that is higher than the normal.Mesophilic are these microbes that prefer areas with moderate temperature.
Through nuclear reactions, such as nuclear fission or fusion, it is possible to change one element into a different element. This process involves altering the number of protons in the nucleus of an atom, resulting in the creation of a new element with different atomic number and properties.
When microbes are in a close nutritional relationship where one benefits and the other is not harmed, it is called commensalism. In this type of symbiotic relationship, the benefiting organism receives nutrients or support, while the other organism remains unaffected. Commensalism is common in various ecosystems, including the human microbiome.
