What is forest biological diversity?
Forest biological diversity is a broad term that refers to all life forms found within forested areas and the ecological roles they perform. In biologically diverse forests, this complexity allows organisms to adapt to continually changing environmental conditions and to maintain ecosystem functions.
What biological diversity means?
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 is biological diversity examples?
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
Why is biodiversity important in a forest?
Forests are critical habitats for biodiversity and they are also essential for the provision of a wide range of ecosystem services that are important to human well-being. There is increasing evidence that biodiversity contributes to forest ecosystem functioning and the provision of ecosystem services.
How do forests support biodiversity?
Forests also provide habitat for a vast array of plants and animals, many of which are still undiscovered. They protect our watersheds. Forests are home to more than three-quarters of the world’s life on land. These ecosystems are complex webs of organisms that include plants, animals, fungi and bacteria.
Why are forests more diverse?
The Janzen-Connell hypothesis, a widely recognized theory introduced in the early 1970s, proposes that a diversity of trees coexist because specialized “natural enemies” — whether they’re herbivorous insects or fungal pathogens — reduce the survival rates of seeds and seedlings.
How important is the biological diversity?
Biodiversity is important to humans for many reasons. Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
What is biological diversity class 10?
Biodiversity is the number and variety of plants, animals and other organisms that are living in an ecosystem. Biodiversity is a measure of the variety of organisms that exist in different ecosystems.
What causes biological diversity?
The various factors that influence biodiversity include -temperature, altitude, precipitation, soils, and their relation with other species. For instance, ocean biodiversity is 25 times lesser than terrestrial diversity. Biodiversity also increases its form as it moves from the poles towards the tropics.
Why forests are called bio diversity hotspots?
Forests are the reservoirs of biodiversity. They are the home of different species of animals, plants, and microbes. They contain the richest diversity of species including the most endangered and rare species. Since forests are rich in species variety they also are subjected to destruction thus considered as hotspots.
Which forest is more diverse?
Tropical rain forests
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Do forests have high biodiversity?
Forests have high biodiversity because the vertical growing surface and resulting canopy shade creates micro-niches by altering locally available light, heat & moisture.
What is forest biodiversity?
Forest Biodiversity. Forest biological diversity is a broad term that refers to all life forms found within forested areas and the ecological roles they perform. As such, forest biological diversity encompasses not just trees, but the multitude of plants, animals and micro-organisms that inhabit forest areas and their associated genetic diversity.
How does the diversity of forest ecosystems affect their biological diversity?
Furthermore, the diversity of forest ecosystems (in both physical and biological features) results in high levels of adaptation, a feature of forest ecosystems which is an integral component of their biological diversity.
What is forestforest?
Forest is a diverse natural habitat system representing the most sumptuous biological areas on Earth. Nearly 30% of the Earth’s surface is covered with forests but it is dwindling because of commercial exploitation.
What is ‘biological diversity’?
‘Biological diversity’ encompasses the variety of existing life forms, the ecological roles they perform and the genetic diversity they contain (FAO, 1989).
