Factors that affect biodiversity in an ecosystem inculde area,climate,diversity of niches,and keystone species. Ecosystem, genetic and cultural diversity, and the connections between these and all species. Extinction is the permanent removal of a species which decreases bio-diversity. These are related because because the system classifies the diversity of species, so the diversity of species I'd related to a system of classification ,.

Life forms are similar because they all descended from the same single species. But as they did so, they evolved so as to fit in and take advantage of their environment. These adaptations led to the diversity. An example of species diversity would be the rainforest. This is because it is a home to many different species of organisms. Species diversity is the number of different species in a particular area species richness weighted by some measure of abundance such as number of individuals or biomass.

However, it is common for conservation biologists to speak of species diversity even when they are actually referring to species richness.

Species need certain genes to survive. Species diversity is the number of different species in a particular area weighted by some measure of abundance such as number of individuals or biomass.

Construct an ancient elephant skeleton. Biodiversity Biodiversity is a measure of the variety of life on Earth. Biodiversity also describes the wealth of habitats that house all life forms and the interconnections that tie them together. Biodiversity does more than provide a variety of products and resources; it also keeps the planet livable for us and for all other species.

Biodiversity helps maintain the atmosphere, keep the soil fertile, purify water, and generally keep the world running smoothly. Environment An environment is defined as all the influences, both biotic and abiotic in nature, which affect an organism.

Biotic factors include all living components of an environment, such as plants and animals, while abiotic factors include all non-living components, such as climate, soil, and water. Thinking environmentally means that no organism can be considered in isolation from any other element of its environment.

Environments are not static things. Evidence for past environmental change abounds in the rock and fossil records. Adaptation Adaptations are any behavioral or physical characteristics of an organism that help it to survive in its environment. A physical adaptation is some type of structural modification made to a part of the body. A fish, for example, is physically adapted to its aquatic environment. It has gills to exchange oxygen and carbon dioxide from water, fins, and a streamlined body to swim through the water.

A behavioral adaptation is something an animal does usually in response to some type of external stimulus. An owl, for example, has behaviorally adapted to avoid predation and competition by becoming nocturnal. Many examples of adaptation of organisms to their environment can be seen in nature. Some of the most successful organisms have very strong specializations for a specific environment.

Environmental Change If environmental change is gradual, organisms can adapt to the change or move to other more suitable areas.
