The three levels of biological diversity are:
(source: AP Biology 7th Edition Textbook, page:1210, Biology 8th and AP edition by Campbell and Reese) 1. Genetic Diversity-genetic variation not only within but also between populations that accounts or adaptions to local conditions. 3. Ecosystem Diversity- the variety of the biosphere's ecosystems.
Ecological diversity refers to the sum of the different types of environment or Ecosystem present in a region or the habitat which is the sum total of the climate, vegetation and geography of a region.
Ecosystem is a unit of the biosphere in which there is an interaction between the living and nonliving factors so as to maintain a continuous flow of energy. It is a structural and functional unit of a biosphere. There are several kinds of habitats or ecosystems around the world. The variety of diversity of species in an ecosystem is influenced by the ecosystem it self.
Examples of ecosystems: Grass land, wet land, desert, aquatic ecosystem etc.
Species diversity is the variety of different species in a given area. It is very difficult to estimate the different species in a given area. Most of the species are found near the equator and a few at the poles.
Genetic Diversity may be defined as variation in genes with a particular species. It refers to the heritable variation. Sexual reproduction play an important role genetic diversity. A species having more genetic diversity can adapt better to the changed environmental conditions.
The three components of biological diversity are the diversity of ecosystems, variety of species that make up the biological community of an ecosystem, and the genetic diversity/variation within each species. Human activity impacts all three of these levels of biodiversity. We are losing many ecosystems at alarming rates including coral reefs and ancient forests, and the diverse species that live in these regions. We've already lost half the world's forests and half the world's wetlands; and, by 1998 we lost 25% of the world's coral reefs. Many scientists believe we are entering the sixth greatest mass extinction, this time, due to human impact.

There are said to be three dimension of biodiversity. The dimensions are genetic biodiversity, functional biodiversity, and taxonomic/ phylogenetic biodiversity.
The three categories of biodiversity can be found in your textbook. I suggest you read it. Your Teacher.

the variation of life forms within a given ecosystem.
A thermobar is used as "a control for random temperature and pressure changes in the room"Dolphin WD. (2008) Biological Investigations: Form, Function, Diversity, and Process. McGraw Hill Higher Education.
Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).
Are you talking the 7 basic levels of classical biological classification? Kingdom Phylum Class Order Family Genus Species Of these, species is the most specific. There are sub-species as well. This is not the only current classification system.
Diversity is the number of different role players (species) in an area. I like to think of diversity in the form of niches. The number of niches being filled in an ecosystem is directly related to the diversity.
Micro-level analysis focuses on individual interactions and behaviors within small groups. Meso-level analysis examines how social institutions and organizations impact individuals and groups. Macro-level analysis studies larger societal structures and systems that influence patterns of social behavior and change.
Center for Biological Diversity was created in 1989.
Biodiversity The variety of all living things; a contraction of biological diversity. Biodiversity can be measured on many biological levels ranging from genetic diversity within a species to the...
International Day for Biological Diversity was created in 1993.
Biological diversity is a National U.S. group. This is a group that uses science.
Answer:Biological diversity is the number and variety of organisms in an areahope that helps
Genetic variability of a speciesSpecies diversity (how many species of all animals, plants etc there are in a biological community)The diversity of biological communities in a (larger) area
Technologies that affect biological diversity include genetic modification. This will cause a loss in biodiversity.
