The numerous factors are responsible for the loss of Biodiversity (Figure 1) such as pollution, habitat loss, hunting, introduction of invasive species, overexploitation of preferred species, climate change, and natural disasters.
How does the environment play a role in biodiversity?
This life, in all its shapes and sizes, occurs in the context of ecosystems: it relies on and interacts with other organisms and the physical environment. … These varying environmental conditions cause natural variations in biodiversity, as well as genetic and epigenetic changes, within and between species over time.
What are the 6 factors that affect biodiversity?
However, a lot of man-made activities impose huge impacts on biodiversity. Below, we discuss six of the major threats to biodiversity: climate change, habitat loss and degradation, pollution, invasive species, over-exploitation and epidemics.
What is environmental biodiversity?
Biodiversity, or biological diversity, is the multitude of living things that make up life on Earth. It encompasses the 8 million or so species on the planet—from plants and animals to fungi and bacteria—and the ecosystems that house them such as oceans, forests, mountain environments and coral reefs.
What factors affect biodiversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4.
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.
What causes threats to biodiversity?
Desertification and deforestation are the main causes of biodiversity loss. … The direct cost of deforestation is reflected in the loss of valuable plants and animal species. Desertification process is the result of poor land management which can be aggravated by climatic variations.
What is environmental value of biodiversity?
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 the best environment for biodiversity?
The highest levels of terrestrial biodiversity are found in tropical forests, which host over 80 per cent of species of terrestrial animals, plants and fungi. Around 1.6 billion people depend on forests for their livelihood, and a quarter of all modern medicines come from tropical forest plants.
How does biodiversity affect the stability of an ecosystem?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
Which environmental and human factors affect biodiversity and populations within ecosystems?
Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species. … Biodiversity is not determined by only one factor, but rather many factors that differ spatially and temporally (Climate, 2005).
What are the 3 factors that make up biodiversity?
Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.
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.
