How does geography affect biodiversity?

One major geographic pattern in biodiversity is the latitudinal gradient in species richness. As one travels further away from the equator, for most taxa, the number of species declines.

How does biodiversity relate to geography?

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.

How does geography affect the diversity of life in a region?

These features include vegetation, climate, the local water cycle, and land formations. Geography doesn’t just determine whether humans can live in a certain area or not, it also determines people’s lifestyles, as they adapt to the available food and climate patterns.

What does biodiversity mean in geography?

Biodiversity refers to the variety of organisms found in a particular habitat. It is important to maintain biodiversity because we rely on it for ecosystem services, which fall into four main categories: provisioning, regulating, cultural, and supporting.

Why is biodiversity important in geography?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. … Healthy ecosystems can better withstand and recover from a variety of disasters.

What are the main causes of biodiversity loss?

CAUSES OF BIODIVERSITY LOSS

  • Climate change.
  • Pollution.
  • Destruction of habitats.
  • Invasive alien species.
  • Overexploitation of the natural environment.
  • Extinction of species.
  • Threat to human beings.
  • Proliferation of pests.

What is biodiversity in geography class 10?

Biodiversity is the sum total of all the varieties of species of plants, animals and micro-organisms living on the earth. It also includes the habitat in which they live.

How geography of a land causes diversity?

Geography influences the way we look, the food we eat and the clothes we wear. India shows great diversity; in terms of geographical features. Following are some examples of diversity which resulted because of difference in geographical features. … Because of the cold climate, people usually wear warm clothes.

What is the biggest cause of biodiversity loss today?

Habitat alteration-every human activity can alter the habitat of the organisms around us. Farming, grazing, agriculture, clearing of forests, etc. This is the greatest cause of biodiversity loss today.

What causes biodiversity patterns?

Biodiversity patterns emerge as a combined result of speciation, extinction and migration, and play an important role in the stability of ecosystems and global climate (Symstad et al., 2003).

How does climate change affect biodiversity?

This very sensitive region is highly affected by climate. Changes in rainfall patterns could also have serious impacts on drylands biodiversity. Climate change could increase the risk of wildfires, which could change the species composition and decrease biodiversity.

What factor affects biodiversity?

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

What is biodiversity What are the threats to biodiversity?

Major direct threats to biodiversity include habitat loss and fragmentation, unsustainable resource use, invasive species, pollution, and global climate change. The underlying causes of biodiversity loss, such as a growing human population and overconsumption are often complex and stem from many interrelated factors.

What is biodiversity and importance of biodiversity?

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.

How does biodiversity increase stability in 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.

Why is biodiversity important to human biodiversity?

Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.
