Biological diversity, or biodiversity, is important to the health of the world's ecosystems. The variety within and between all species of plants, animals and microorganisms and the ecosystems where they live and interact is biodiversity. The diversity of species is not evenly distributed throughout the planet because life depends on factors like temperature, altitude, and the presence of other species. We can prove this because tropical regions support more life than polar regions. Biodiversity is important to sustaining life on earth because it prevents anyone species from throwing the balance of nature out of order.
How do humans affect biodiversity? Humans affect biodiversity through habitat destruction, overkill, introduced species and overpopulation.
Life in a small habitat, like a pond, can teach you about the lifecycle of many different plants and animals that live in and around a pond. A pond is a specialized ecosystem and contains insects, birds, reptiles, mammals and fish. Ponds are small freshwater habitats that provide a home to many plants and animals. Many of the creatures that live in a pond are too small to be seen with the naked eye. Inside the water are tiny floating organisms called plankton. Plankton can either be animal or plant like. An ecosystem is a biological community of interacting organisms and their physical environment. An ecosystem includes all of the living things in a given area. An ecosystem would include plants, animals and organisms. These living creatures interact with nonliving environments including the rocks, sand and soil. In an ecosystem each organism has its own role to play.
