Which level of biological classification do mammalia and hominidae represent, respectively?

Taxonomic groups are used for biological classification. There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. If we take a look on Mammalia and Hominidae classification, we can assume that Mammalia represents class, and Hominidae represents family:

1. Domain: Eukarya

2. Kingdom: Animalia

3. Phylum: Chordata

4. Class: Mammalia

5. Order: Primates

6. Family: Hominidae

7. Genus: Homo

8. Species: Homo sapiens

Class and Family

Explanation:

The distribution of aquatic life is affected by the aquatic factors due to the ecological balance which exist in a spot inside the aquatic ecosystem.

Explanation:

An ecosystem is the interaction between the living thing which is biotic factors and non living things which are abiotic factors, inside an environment. These factors together constitute the aquatic factors.

The abiotic factors are like sunlight, temperature, chemical composition, water disturbances and terrain. The biotic factors depends upon these for their distribution or presence of life. Like the one who survives within bright sunlight must dwell in upper stream of waters and the one survivng in dark waters, then comes with other factors as living in terrain with no disturbance or with some water disturbances.
