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.

Biodiversity and Extinction. The biodiversity of an area is literally the number of species, both plant and animal, inhabiting the environment being examined. When a species is no longer found in a region, it is locally extinct. When it is no longer found anywhere, the species is considered extinct.

The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. Due to human activities, populations of many species have become small and isolated.

Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things (biota) depends on temperature, precipitation, altitude, soils, geography and the presence of other species.

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

Biodiversity conservation protects plant, animal, microbial and genetic resources for food production, agriculture, and ecosystem functions such as fertilizing the soil, recycling nutrients, regulating pests and disease, controlling erosion, and pollinating crops and trees.

Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction. ... Genetic Diversity is the diversity of genetic characteristics (expressed or recessive) within a species (i.e. between individuals and populations of the same species).

Habitat destruction, climate change, invasive species, pollution, the human population growth, and overharvesting are the greatest threats of biodiversity. You just studied 30 terms!

There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption. Through the activity, students will create a list of reasons why animals can become extinct.

The earth's biodiversity is in grave danger. ... Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.

Often referred to as "biodiversity", biological diversity refers to the variety of species and ecosystems on Earth and the ecological processes of which they are a part. Three components of biodiversity are ecosystem, species and genetic diversity.

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

Biodiversity is the amount of variety of life on Earth. It is the number of different species of plants, animals, and microorganisms. ... Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Support a larger number of plant species and, therefore, a greater variety of crops.

Levels of biodiversity. Biodiversity is usually explored at three levels - genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.
