What is binomial nomenclature? <br>​
Mrrafil [7]

Answer:

In taxonomy, binomial nomenclature ("two-term naming system"), also called binominal nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, binominal name or a scientific name; more informally it is also called a Latin name.

Varvara68 [4.7K]

Answer:

The answer is option B. autotrophs

Explanation:

Decomposers release nutrients like nitrogen and carbon dioxide as well as water when they feed on dead plants and animals. Decomposers include fungi, bacteria and earthworms.

These nutrients are released into air, soil and water and serve as nutrients for autotrophs. Autotrophs produce their own food from sunlight energy, water and carbon dioxide. Example include green plants; which by the process of photosynthesis produce their own food using carbon dioxide and soil nutrients.
