What are the three levels of biological diversity?

Answer 1

The three levels of biological diversity are:

1. Genetic diversity
2. Species diversity, and
3. Community and ecosystem diversity.

Answer 2

(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.

Answer 3

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.

Answer 4

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.

Answer 5

1. Genetic Diversity

2. Species Diversity

3. Ecosystem Diversity

Answer 6

genetic diversity, species diversity, ecosystem diversity.

Answer 7

There are said to be three dimension of biodiversity. The dimensions are genetic biodiversity, functional biodiversity, and taxonomic/ phylogenetic biodiversity.

Answer 8

The three categories of biodiversity can be found in your textbook. I suggest you read it. Your Teacher.
