Four major components of biodiversity are:
1. Genetic diversity - refers to the genetic variation that occurs among members of the same species.
2. Species diversity - (taxonomic diversity) refers to the variety of species or other taxonomic groups in an ecosystem
3. Ecosystem diversity - refers to the variety of biological communities found on earth. With ecosystem diversity, its two levels are generally considered, which are communities and ecosystems.
4. Functional diversity - refers to the variety of biological processes, function or characteristics of a particular ecosystem.
A controlled variable is not changed throughout an experiment. It is there so that the other variables being tested on can be better understood.
Geologists can 'read' rock layers using relative and absolute dating techniques. ... Relative dating arranges geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (the rock layers are called strata).
An advantage of conservation is B.
