These break off to produce “new” plants, resulting in a genetically uniform population. Similarly, the tiny plant known as duckweed (Lemna minor), which grows on the surface of fertile waterbodies, propagates by developing small vegetative buds on the edge of its single leaf. Such aspen clones may be the world’s largest “individual” organisms (in terms of total biomass). In such species, genetically uniform clones can develop, which consist of plants that, although discrete, nevertheless constitute the same genetic “individual.” For example, clones of trembling aspen (Populus tremuloides) can develop through vegetative propagation, in some cases covering more than 40 ha and consisting of thousands of trees. Some plants, for example, have little or no genetic variability, usually because the species relies on asexual (vegetative) means of propagation. However, there are exceptions to this generalization. This variation constitutes genetic biodiversity at the level of populations, and ultimately of the species. In almost all species, individuals differ genetically – that is, in terms of information encoded in their DNA.

and the variety and dynamics of ecological communities on larger scales, such as landscapes and seascapes.

numbers of species (also known as species richness).

genetic variation within populations and species.

It is often considered to have three levels of organization:

Define the classification of life in terms of species, genus, family, order, class, phylum, and kingdom.īiodiversity is the richness of biological variation.

Explain the reasons why biodiversity is important and should be preserved.

Outline the concept of biodiversity and explain its constituent elements.
