What are the two different aspects of biodiversity?

Types of Biodiversity. Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).

What are the aspects of biodiversity?

Definition: Biodiversity refers to the variety and variability among living organisms and ecological compliances in which they occur. Major components in biodiversity are ecosystem diversity, species diversity and genetic diversity.

What are the different types of biodiversity quizlet?

The three different types of biodiversity are species, genetic and ecosystem diversity.

What are three aspects of biodiversity?

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.

What are two different scales on which biodiversity can be measured?

Biodiversity can be measured at many different levels including genetic, species, community, and ecosystem. One way to measure biodiversity is to assess species richness of an ecosystem, which is the total number of distinct species within a local community.

Why are there differences in biodiversity?

Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction. … Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth).

What do you mean by biodiversity aspect?

More in Center for Biodiversity & Conservation. The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.

What are the two measures of species diversity in an ecosystem?

Biodiversity is basically the variety within and among life forms on a site, ecosystem, or landscape. Biodiversity is defined and measured as an attribute that has two components — richness and evenness. Richness = The number of groups of genetically or functionally related individuals.

What are the two main categories of ecosystems?

Natural ecosystems are basically classified into two major types. They are aquatic ecosystem and terrestrial ecosystem.

What are the four key aspects of biodiversity?

The four major components of biological diversity are: Functional Diversity (biological or chemical processes such as energy flow and matter recycling needed for the survival of species, communities, and ecosystems), Ecological Diversity (the variety of terrestrial and aquatic ecosystems found in an area or on the …

What are the 4 types of biodiversity quizlet?

The four major components of biodiversity are species diversity, ecological diversity, genetic diversity, and functional diversity. Biodiversity is important because it allows for organisms to adapt to their environment, and to survive dramatic environmental changes.

What are the two descriptions that define a wetland?

Wetlands must have one or more of the following three attributes: 1) at least periodically, the land supports predominantly hydrophytes; 2) the substrate is predominantly undrained hydric soil; and 3) the substrate is saturated with water or covered by shallow water at some time during the growing season of each year.
