Which of the following is are a likely reason for the migration of native species from an area?

Which of the following is (are) likely reasons for the migration of native species from an area? A new housing development clears a large forest. Species are separated from the rest of their population. … Which of the following is an example of how a biotic factor can affect the population dynamics in an ecosystem?

What is a possible cause for a decrease in ecosystem?

Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.

What happens to the other members of the food chain if the cat is removed quizlet?

Garden plants are eaten by snails, which are eaten by birds, which are eaten by the household cat. What happens to the other members of the food chain if the cat is removed? … The number of plants increases and the number of snails and birds decrease.

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

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. Adding an organism to a food chain does not affect the other members of the food chain, but removing an organism does.

Which of the following is most likely to cause a decrease in 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. In each case, human beings and their activities play direct roles.

Which of the following is a cause for a decrease in biodiversity?

What are the causes and why does biodiversity matter? 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.

Why does an increase in biodiversity lead to an increase in ecosystem stability?

It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. … This increase in complexity makes it more likely that the ecosystem will return to a stable state after a disturbance, because the ecosystem has more ways to respond to a disturbance and fix problems.

How does a decrease in biodiversity impact an ecosystem?

Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).

How can an increase in biodiversity lead to an increase in ecosystem state ability?

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.

What causes high biodiversity?

Unique Climates and Conditions

One of the most significant and naturally occurring causes of differences in biodiversity across the world is differences in climate. … On the other extreme, moist, tropical zones like the Amazon rainforest support some of the highest levels of biodiversity in the world.

How does high biodiversity affect 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.

How does biodiversity affect the ecosystem?

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.

Why is biodiversity important 5 Reasons?

Biodiversity Protects Us. Biodiversity makes the earth habitable. Biodiverse ecosystems provide nature-based solutions that buffer us from natural disasters such as floods and storms, filter our water and regenerate our soils.

What are the causes of loss of biodiversity class 12?

Causes for Loss of Biodiversity
  • Habitat loss and fragmentation.
  • Over-exploitation.
  • Alien species invasions.
  • Co-extinctions.

What are some other reasons for why biodiversity is higher in tropical regions that others?

The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.

What are 10 reasons why we should care about biodiversity?

Having biodiversity improves the health of Earth. It shows it is thriving. And healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. Biodiversity provides raw materials and resources for medicines and other purposes.

What are the 3 types of biodiversity?

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.

What is biodiversity and why it is important?

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. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.

What are the natural causes of species extinction?

The extinction of any species is an irreversible loss of part of the biological richness of the Earth. Extinction can be a natural occurrence caused by an unpredictable catastrophe, chronic environmental stress, or ecological interactions such as competition, disease, or predation.

What are examples 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.
