Answer:
You will use the Linée Classification System
Step-by-step explanation:
Linée, the naturalist, physician and teacher, created a system of classification and nomenclature of living things in 1735, which is still used today with few modifications.
In Linée's system, all living things are grouped into different categories. In all there are seven taxonomic categories. The largest and most comprehensive is the kingdom. Each kingdom is divided into phyla. Each phylum is subdivided into classes. Each class is subdivided into orders. Each order is subdivided into families. Each family is subdivided into gender. Each genus is subdivided into species.
The species is the basic category. In it are individuals who are capable of reproducing among themselves and of producing fertile descendants.
Thus, the Linée Classification and Naming System is the best system for an ecologist to correctly classify and name that algae.
