What factors affect biodiversity and the relationships between species and the physical environment?

What are some factors that can affect the biodiversity of an ecosystem?

Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).

What is the relationship between biodiversity and the physical environment?

Biodiversity is the variety of life on Earth. 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.

What are the 6 factors that affect 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 are 5 things that affect biodiversity?

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.

What are the 3 factors that make up biodiversity?

Levels of 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. …
  • Species diversity. …
  • Ecosystem diversity.

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.

How is the species diversity related to the environmental condition of the species?

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.

How does invasive species affect biodiversity?

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

What is the effect of high and low diversity in an ecosystem?

Productivity and stability as indicators of ecosystem health

An unstable ecosystem will be more likely to lose species. Thus, if there is indeed a link between diversity and stability, it is likely that losses of diversity could feedback on themselves, causing even more losses of species.

What causes species diversity?

Species diversity is caused by evolution. A region becomes diverse with the evolution of different species in an area.

What is species diversity in environmental science?

Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth). … A biological community is defined by the species that occupy a particular area and the interactions between those species.

What causes biodiversity?

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.

What are the 4 major threats to 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 are the traditional and environmental issues that affect biodiversity and sustainability?

Land use change, pollution, poor water quality, chemical and waste contamination, climate change and other causes of ecosystem degradation all contribute to biodiversity loss and, can pose considerable threats to human health.
