What causes biodiversity biology?

What causes biodiversity to happen?

The various factors that influence biodiversity include -temperature, altitude, precipitation, soils, and their relation with other species. For instance, ocean biodiversity is 25 times lesser than terrestrial diversity. Biodiversity also increases its form as it moves from the poles towards the tropics.

What are the five primary causes of biodiversity loss?

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.

What causes threats to biodiversity?

Desertification and deforestation are the main causes of biodiversity loss. … The direct cost of deforestation is reflected in the loss of valuable plants and animal species. Desertification process is the result of poor land management which can be aggravated by climatic variations.

What are the four main threats to biodiversity?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What are causes of deforestation?

Deforestation causes can either be direct or indirect. Among direct causes are: Natural causes as hurricanes, fires, parasites and floods. Human activities as agricultural expansion, cattle breeding, timber extraction, mining, oil extraction, dam construction and infrastructure development.

What is the biggest threat to the loss of biodiversity?

Habitat Fragmentation

Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.

Which is not a major causes of biodiversity loss?

Keeping animals in zoological parks is not a cause for loss of biodiversity rather it is a method of conservation of biodiversity.

What are the three main levels of biodiversity quizlet?

Biodiversity is the variation of life forms in a particular ecosystem. All levels of biodiversity are interconnected, but there are three levels at which biodiversity is broken down and studied: genetic diversity, species diversity and ecosystem diversity.
