Which of the following is an example of something that would decrease biodiversity?

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

What are the causes of loss of biodiversity?

CAUSES OF BIODIVERSITY LOSS

  • Climate change.
  • Pollution.
  • Destruction of habitats.
  • Invasive alien species.
  • Overexploitation of the natural environment.

Which of the following is an example of biodiversity?

Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.

What factors increase biodiversity?

As a general rule, increasing biodiversity can be achieved by diversifying the range of habitats or vegetation structures available at a site. This can be achieved by, for example, varying mowing regimes, planting or seeding with native tree and shrub species, or occasional soil disturbance.

Where is biodiversity loss happening?

Micronesia and Polynesia. Called the “epicenter of the current global extinction,” by Conservation International, this smattering of more than 4,000 South Pacific islands is at risk from both local human activity and global climate change. Humans settled on these islands between 2,000 and 3,000 years ago.

How can we reduce biodiversity loss?

10 Ways to Protect and Conserve Biodiversity

  1. Government legislation.
  2. Nature preserves.
  3. Reducing invasive species.
  4. Habitat restoration.
  5. Captive breeding and seed banks.
  6. Research.
  7. Reduce climate change.
  8. Purchase sustainable products.

What happens when biodiversity decreases?

Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply.

Why is biodiversity on Earth decreasing?

Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

How does loss of biodiversity affect animals?

The loss of biodiversity has two significant impacts on human health and the spread of disease. … 8 As habitats are broken apart and reduced in size, these animals become more common, winning out over the species that do not typically transmit disease.

Which statement best explains why biodiversity on Earth is decreasing?

Biodiversity has decreased because a variety of habitats have been reduced. Which statement best explains why biodiversity is important for all life on Earth? High biodiversity changes an ecosystem by reducing the survival rate of all but the individuals best suited to an area.

What is low biodiversity?

Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.

IMPORTANT:  Question: How does habitat loss affect the Arctic?

Does biodiversity decrease near the equator?

Species diversity is higher at the equator than at the poles. In biological terms, this is referred to as the latitudinal diversity gradient (LDG), in which the number of species increases from the poles to the Equator. This ranks among the broadest and most notable biodiversity patterns on Earth.

When might an increase in biodiversity lead to a decrease in the stability of an ecosystem?

An increase in biodiversity usually leads to an increased stability, but in the case of an invasive species it would lead to a decreased stability.

How might a reduction in species diversity affect the other three components of biodiversity?

Reduced genetic diversity increases the probability of species extinction or of substantial reductions in the population of a species due to changing environmental conditions (such as, a change in climate or the introduction of a new disease).
