Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
Insects are not a species. Insects are are a class of invertebrates within the arthropod phylum. That is like asking if mammals are the most numerous species. Your question needs to be refined. Are you asking if insects are the most numerous class of animal? Most numerous species of living thing? Or perhaps you are thinking of a specific species such as monarch butterfly (Danausplexippus).
This question is vague therefore I have provided two answers and explanations. The single cell is the smallest living unit within a living system. Quarks are the smallest particles of matter and atoms which composes all living things.
Human species, as in the variation in height.

Biodiversity is the measure of the number of species living within an ecosystem.

Biotic Factors
A species. A community is a group of a species of animal living in a certain area, whereas a species is all of the animals worldwide contained within the species.
Enzymes
a biotic component is a non living organizim such as a rock
A somewhat regular progression of species replacement is succession. The number of species living within an ecosystem is a measure of its biodiversity.
a phylum
The amount of living things within an area
