Which of the following is not a level of bio diversity?
Hint: The variety of life on earth and variation at the genetic and species level of the ecosystem is biodiversity. It is richer in the tropics and is not evenly distributed on Earth. Complete answer: Lesser interspecific competition is not observed in biodiversity Hotspots.
What are the negative effects of biodiversity?

Which of the following is a benefit of biodiversity quizlet?
Humans benefit from biodiversity as a source of food, medicine, and raw materials. Biodiverse ecosystems provide benefits to humans, like cleaning water or pollination of crops.
Which things are a direct benefit of biodiversity?
Ecosystem services provided by biodiversity include ecosystem stability and productivity; maintaining and renewing soils, water supplies, and the atmosphere; nitrogen fixation and nutrient recycling; pollination, pest and disease control, and waste disposal.
What are the 5 main reasons for biodiversity decline?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming.
Is economic value a benefit of biodiversity?
Food production relies on biodiversity for a variety of food plants, pollination, pest control, nutrient provision, genetic diversity, and disease prevention and control. Both medicinal plants and manufactured pharmaceuticals rely on biodiversity.
What are the benefits of biodiversity?
The four key benefits are: (1) Biodiversity Provides the Natural Resource, (2) Biodiversity Provides the Genetic Resource, (3) Biodiversity Maintains a Stable Ecosystem, and (4) Biodiversity Ensures Optimum Utilization and Conservation of Abiotic Resources in an Ecosystem.
Which region has the richest biodiversity?
Tropical regions are having the richest biodiversity in the world, most of the nutrients are lodged in its biotic community. Due to warm and humid conditions decomposition of organic matter and regeneration of nutrients take place rapidly.
What are microbes good for?
Microbes are also good sources of various medicinally important enzymes ( streptokinase and asparginase), toxins (botulin), immunomodulators (Cyclosporin A) etc. Vaccines such as BCG, typhoid, hepatitis B, and alkaloids such as ergot are also derived from some microbes.
How does vegetation affect soil?
Luxuriant growth of vegetation hinders rapid flow of water, binds soil particles together and prevents soil erosion. Loss of biodiversity reduces the efficiency of this vital machinery which in turn results in rapid losses of nutrients and degradation of soil.
Why are plants important to humans?
The most important contribution of plants is to provide food to ever increasing human population.
Where do minerals stay in the soil?
The minerals remain in the soil while organic matter lies on the forest floor. As most of the minerals are used by the biotic community of an ecosystem the nutrient loss is prevented. Mineral nutrients are not lost to the flowing waters, rains and floods which are frequent in the tropics.
How does biodiversity benefit humans?
Benefits of Biodiversity to Human Health and Well-being. Exposure to biodiversity in nature has multiple benefits to both mental and physical health at any age. THE NATIONAL PARK SYSTEM hosts some of the most diverse resources found anywhere on the planet. Parks host more variety in plant and animal organisms than almost any other land use ...
Why is biodiversity important?
Biodiversity gives resilience—from the microbes that contribute to the formation of the human biome to the genes that help us adapt to stress in the environment—supports all forms of livelihoods, may help regulate disease, and is necessary for physical, mental, and spiritual health and social well-being . Biodiversity can be explored in ...
What are the supporting services of biodiversity?
Supporting services are the ways in which biodiversity provides the building blocks for life. Supporting services are necessary for all other ecosystem services to exist. These include primary production (i.e., photosynthesis and chemosynthesis) of new organic matter, cycling of nutrients necessary for life, and pollination. Without this constant creative process, life would quickly grind to a halt. Primary productivity is a key determinant of biodiversity (Rosenzweig 1995), meaning that plants and animals alike are dependent upon this supporting service for survival. Humans may be the best example of this, as humans are estimated to use or co-opt 40% of all net primary productivity (Vi tousek et al. 1986).
What is biodiversity in parks?
The biodiversity in parks serves many of these regulating services, whether it be flood mitigation from parks with swamps and floodplains, disease-regulating services of predators and other wildlife species that reside in parks, or clean air and water.
Why is the National Park Service important?
Fortunately, the National Park Service is well positioned to raise understanding and appreciation of the values and benefits of biodiversity to protect and preserve our two most vital resources: nature and people.
How does biodiversity affect the environment?
Biodiversity influences how disease occurs in an individual or population, how the local climate is able to support life, and how resilient an area will be against flooding or a catastrophic storm. Regulating services are the processes that renew resources and ensure a functional, habitable environment.
What is the primary productivity determinant of biodiversity?
Primary productivity is a key determinant of biodiversity (Rosenzweig 1995), meaning that plants and animals alike are dependent upon this supporting service for survival.
The Biodiversity Crisis
Biologists estimate that species extinctions are currently 500–1000 times the normal, or background, rate seen previously in Earth’s history. The current high rates will cause a precipitous decline in the biodiversity of the planet in the next century or two. The loss of biodiversity will include many species we know today.
Types of Biodiversity
A common meaning of biodiversity is simply the number of species in a location or on Earth; for example, the American Ornithologists’ Union lists 2078 species of birds in North and Central America. This is one measure of the bird biodiversity on the continent.
Patterns of Biodiversity
Biodiversity is not evenly distributed on the planet. Lake Victoria contained almost 500 species of cichlids (just one family of fishes that are present in the lake) before the introduction of an exotic species in the 1980s and 1990s caused a mass extinction. All of these species were found only in Lake Victoria, which is to say they were endemic.
Importance of Biodiversity
Loss of biodiversity may have reverberating consequences on ecosystems because of the complex interrelations among species. For example, the extinction of one species may cause the extinction of another.
