Ecosystems that have biodiversity are very productive, recycling nutrients easily and quickly. Such ecosystems are healthy, self-sufficient and better able to overcome disasters. Biodiversity acts as a system of checks and balances; if one part of an ecosystem weakens for awhile, stronger parts help it survive.
High levels of biodiversity provide natural resources and services to each animal and plant species in an ecosystem. Different species can protect water and soil resources, store and recycle nutrients, break down pollution and contribute to the climate's stability. High levels of biodiversity also help maintain ecosystems and help them recover from chaotic events such as volcanic eruptions, droughts, floods and deforestation.Learn More
A few threats to biodiversity include urbanization and the construction of new roads, the increasing human population, the transportation industry and owning exotic pets.

They live in the northern hemisphere of America, Europe and Asia. The gray wolf once roamed over two-thirds of the United States until intense hunting threatened the species to extremely low levels in the 1930s.Full Answer >
Ecological balance is important for the continued survival and existence of organisms as well as the stability of the environment. The natural balance in the ecosystem, which must be maintained, may be disturbed as a result of natural hazards, the unexpected death of a particular species, man-made causes or the introduction of new species to the ecosystem.Full Answer >
Ecological assessment refers to the monitoring of ecological resources to determine current and changing conditions. It is a process of evaluating the likelihood that the environment may have been affected as a result of being exposed to environmental stressors, including chemicals, disease, climate change and land change.Full Answer >
