What are the three major components of a cladogram?

A cladogram is a branching diagram that shows the cladistic relationship between a number species. It comes from the greek clados meaning branch and gramma meaning character. It is not to be confused with an evolutionary tree since it does not show the relationship between ancestors and descendants plus it also lacks the ability to show how they have changed over time. The major components of a cladogram are the tip (the start of the lineage), root (the end of the lineage) and node (where two or more lineages combine).

Interacting group of various species in a common location. for example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
