The atomic mass or mass number of an atom is written as superscripts attached to the symbol of that element.
<h3>Atomic mass or mass number</h3>
- The atomic mass or mass number of an atom of an element is the sum of the number of protons and neutrons in the nucleus of the atom.
The atomic mass or mass number of an atom is usually written as superscripts attached to the symbol of that element.
For example, given an element X, the atomic mass or mass number can be shown as follows: 
where a = atomic number
b = atomic mass/mass number
Therefore, the atomic mass or mass number of an atom is written as superscripts attached to the symbol of that element.

Options for the question have not been given. They are as follows:
A) parasitism
B) mutualism
C) inhibition
D) facilitation
E) commensalism
Answer:
D) facilitation
Explanation:
In ecology, facilitation is used to describe community interaction between two species in which at least one of the species is benefited. One species "facilitates" survival of another species and hence the term facilitation. They can provide facilitation by providing them refuge from predation, competition, physical stress etc.
Facilitation is broadly of two types, mutualism and commensalism. In mutualism, both the interacting organisms are benefited. In commensalism, one organism is benefited and another one is neither benefited nor harmed.
