it is difficult to use criterion of interbreeding to define species of unicellular organisms because not all organisms undergo the same process. these species come from the class and groups thus making it even harder.
The smallest grouping that only contains one kind of organism is called a species. Each species consists of individuals that are capable of interbreeding and producing fertile offspring.
A species that meets this criterion is Homo sapiens (humans), where individuals typically have the same number and pattern of fingers and toes each time they are formed.
Without more information, it is difficult to determine which type of organism is represented by x. It could be a plant, animal, fungus, bacteria, or other type of organism depending on the context in which x is being referenced.
Rapid and extreme environmental changes are most difficult for organisms to adjust to because they can disrupt the balance of ecosystems and outpace an organism's ability to adapt through natural selection. These changes can lead to extinction events or severe declines in populations.
Scientists cannot determine the exact color and texture of a fossil organism with certainty, as these features are typically not preserved in the fossilization process. Additionally, the specific behaviors or ecological interactions of the organism are difficult to ascertain, as these traits rely on living observations and environmental contexts that are not available from fossils alone.
Because
An individual is a single organism belonging to a population, which is a group of individuals of the same species living in the same area and capable of interbreeding.

It's not so much the organism or a type of organism that is difficult to define as a species but rather the differences in the theories regarding the definition of the word 'species'. For example the Biological species concept and phylogenetic species concept can be at odds when looking at convergent/parallel evolution.
Rapid and extreme environmental changes, such as sudden temperature spikes or severe habitat destruction, are usually the most difficult for organisms to adjust to. These changes can disrupt an organism's ability to find food, shelter, and reproduce in a short period, leading to population declines or extinction.

Since a group may have only one member then the DNA code would probably define individual organisms (as opposed to Species of organism, subspecies, breed [in dogs, sheep, etc.], location, etc.). Each organism will be completely different to another-unless it is a twin or grown from a part of the old organism (in the case of a plant), so called clones have different DNA.
A population. This term is used to describe a group of organisms of the same species living in the same area and capable of interbreeding to produce viable offspring.
A species that meets this criterion is Homo sapiens (humans), where individuals typically have the same number and pattern of fingers and toes each time they are formed.
