What are the three factors that affect extinction?

There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption.

What is the most important factor that leads to extinction?

The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming.

What are the factors that causes species extinction?

Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).

What factors have caused the extinction of some species of plants and animals?

Species endangerment and extinction have three major anthropogenic causes—overhunting or overharvesting; introduction of nonnative species, including the spread of disease; and habitat degradation or loss.

What are the 7 natural causes of extinction?

The extinction of any species is an irreversible loss of part of the biological richness of the Earth….Habitat Disturbance

• Marine aggregate dredging.
• Trawl fishing.
• Reclamation of coastal wetlands (mangroves, salt marshes) for economic uses.
• Coastal protection structures.

What factors have caused the extinction of some species of plants and animals Brainly?

Increasing population growth, pollution, uses of fertilizers etc in agriculture are the causes of extinction of wildlife species.

What factors have caused the extinction of some species of plant and animals?

Species endangerment and extinction have three major anthropogenic causes—overhunting or overharvesting; introduction of nonnative species, including the spread of disease; and habitat degradation or loss. All three causes probably were factors in prehistoric as well as modern times.

What factor has caused the extinction of some species of plant and animal?

Destruction of Habitat As the human population grows, more and more land has to be cleared and urbanized for living space. This shrinks habitat for animals and plants. Each year, 36 million acres of natural forest are leveled, according to the World Wildlife Fund.

What factors have caused the extinction of some species of plant and animal?

An endangered species is a type of organism that is threatened by extinction. Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago.

What is the main cause of extinction of plants and animals?

The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. They release oxygen into the atmosphere, absorb carbon dioxide, provide habitat and food for wildlife and humans, and regulate the water cycle.

What are the main causes of the extinction of Philippine wildlife?

Causes of Extinction

• Exotic species introduced by humans into new habitats.
• Over-harvesting of fish, trees, and other organisms.
• Global climate change, largely due to the burning of fossil fuels.
• Pollution, which adds chemicals, heat, and noise to the environment beyond its capacity to absorb them.
