What are types of biodiversity?
Types of Biodiversity. Biodiversity includes three main types: diversity within species (genetic diversity) , between species (species diversity) and between ecosystems (ecosystem diversity).
What has the greatest impact on biodiversity?
Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity.
What factors affect biodiversity Why do wetlands have a high level of biodiversity?
Wetlands have a high level of biodiversity because of the amount of resources available . The high levels of accessible water, nutrient levels, and primary productivity allow for a large number and variety of organisms at the base of the food web.

- Destruction of habitats.
- Invasive alien species.
- Overexploitation of the natural environment.
How does heavy pollution affect biodiversity in the stream?
Eutrophication, the process of accumulation of nutrients, including nitrogen , in water bodies, often results from air pollution. Nutrient overloads in aquatic ecosystems can cause algae blooms and ultimately a loss of oxygen, and of life. As ecosystems are impacted, so is the biological diversity.
How do land use changes affect biodiversity?
Human land-use is a primary cause of biodiversity loss. A recent study shows that human changes to ecosystems has pushed global biodiversity loss beyond safe limits , which could reduce nature’s resilience. ... Changing original ecosystems could harm biodiversity ultimately reducing ecosystem function.
Which of the following environmental threats has affected global biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change , and overexploitation.
Which of the following is the most direct threat to biodiversity?
The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and the introduction of exotic species . The first two of these are a direct result of human population growth and resource use. The third results from increased mobility and trade.
Why is biodiversity important 5 Reasons?
Biodiversity Protects Us. Biodiversity makes the earth habitable . Biodiverse ecosystems provide nature-based solutions that buffer us from natural disasters such as floods and storms, filter our water and regenerate our soils. ... Protecting and restoring natural ecosystems is vital to fighting climate change.
What is biodiversity and its threats?
Threats to Biodiversity. The greatest threat leading to the loss of biodiversity is the human race . As our population grows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural ones.
What is biodiversity in PDF?
Biodiversity is the variety of different forms of life on earth , including the different plants, animals, micro-organisms, the genes they contain and the ecosystem they form. It refers to genetic variation, ecosystem variation, species variation (number of species) within an area, biome or planet.
What are the three biggest threats to biodiversity?
The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species .
What factors affect biodiversity in wetlands?
Climate, soil, human disturbance, and terrain are thought to be the main factors affecting the distribution of wetlands (Halsey et al., 1997, Johnson et al., 2005).
What is biodiversity for kids?
Biodiversity is the rich variety of life on Earth . There’s variety in genes, variety among species, and a variety of ecosystems. Everything is interconnected, or dependent on everything else!
How does biodiversity affect ecosystem services?
Many key ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity . Promoting the healthy functioning of ecosystems ensures the resilience of agriculture as it intensifies to meet growing demands for food production.
What is the greatest impact on biodiversity caused by agriculture?
Industrial agriculture also wreaks havoc on biodiversity within soil . Communities of insects and other invertebrates have their habitats disturbed when farmers plow up soil, interrupting their ability to recycle dead plants into the rich, stable organic carbon that makes soils fertile.
How does wetlands affect biodiversity?
Wetlands are highly productive and biologically diverse systems that enhance water quality, control erosion , maintain stream flows, sequester carbon, and provide a home to at least one third of all threatened and endangered species. Wetlands are important because they: improve water quality. provide wildlife habitat.
What causes high biodiversity?
Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth , like the warm and wet climate of tropical regions. Ecosystems can also contain species too small to see with the naked eye.
How does pollution affect biodiversity?
For example: pollutants such as sulfur can lead to excess levels of acid in lakes and streams, and damage trees and forest soils ; atmospheric nitrogen can reduce the biodiversity of plant communities and harm fish and other aquatic life; ozone damages tree leaves and negatively affects scenic vistas in protected ...
How does overpopulation affect biodiversity?
Population growth and increasing resource consumption affect biodiversity in two ways: They create pressure to convert wildlife habitat into agricultural and urban land ; and. They produce wastes that pollute habitat and poison wildlife.
