What makes up the biodiversity of a region Why does it vary due to climate and altitude?

Why does biodiversity vary due to climate and altitude? Because most plants and animals are finely tuned members of a local ecosystem that depends on the temperatures and moisture of their surrounding. … Desert conditions are harsh and support few species, with lowbiodiversity. Tropical jungles support many species.

What makes up the biodiversity of a region?

Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.

Why does climate change affect biodiversity?

As the planet warms quickly, mostly due to human activity, climate patterns in regions around the world will fluctuate. Ecosystems and biodiversity will be forced to fluctuate along with the regional climate, and that could harm many species.

How does biodiversity contribute to climate stability?

Biodiversity – Contribution to climate stability. Vegetation influences the climate at macro and micro levels. … On smaller scales, vegetation has a moderate influence on local climates and may create quite specific microclimates. Some organisms are dependent on such microclimates for their existence.

How does climate affect ecosystems and the life within them?

Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs. Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought.

What are the factors that affect the balance in biodiversity?

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

What is biodiversity explain different levels of 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.

How does climate change affect biodiversity Brainly?

Explanation: Rising temperatures are likely to result in widespread ecological change. Many animal and plant species are likely to become extinct as ecosystems adjust to climate change. While adaptable species will survive, and other migrate, the end result will be lost biodiversity.

How does climate change affect the biodiversity of marine ecosystems?

Climate change due to human activity has a direct impact on marine species. It alters their abundance, diversity and distribution. Their feeding, development and breeding, as well as the relationships between species are affected. Rising temperatures lead to different behaviour patterns according to species.

What are the causes of climate change?

The main causes of climate change are:

  • Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry.
  • Deforestation – because living trees absorb and store carbon dioxide.

Why do warmer climates provide greater biodiversity?

Diversity increases with temperature

The warmer it is, the greater the diversity. “The more groups of animals and plants you investigate in parallel, the greater the significance of temperature for explaining biodiversity, whereas the importance of all other variables decreases accordingly.”

How does biodiversity help to buffer the impacts of climate change?

Healthy ecosystems must lie at the centre of any adaptation policy and can help mitigate climate change impacts, by absorbing excess flood water or buffering us against coastal erosion or extreme weather events. Forests, peatlands and other habitats are major stores of carbon.

How does biodiversity increase ecosystem stability quizlet?

How can an increase in biodiversity lead to an increase in ecosystem stability? … An increase in the biodiversity of an ecosystem leads to an increase in its productivity. T. Ecosystems with greater biodiversity have an increased stability.
