What is the biggest cause of biodiversity?
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 factors control the current pattern of biodiversity on earth justify your answer?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
What is the biggest threat to the loss of biodiversity essay?
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 well known pattern of biodiversity?
Latitudinal gradient – This is the most well-defined and well-known pattern of biodiversity studies till date. According to this pattern, the species diversity follows a regular pattern as we move from the equator to the polar regions.
Does biodiversity follow any patterns?
Does species diversity follow any patterns? The diversity of species is lowest at the poles and increases toward the equator, with the deserts being obvious exceptions. Tropical rainforests and coral reefs are among the planet’s richest and most complex ecosystems.
What are the three patterns of biological diversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
What are global patterns?
Students identify global patterns and connections in environmental data that include soil moisture, insolation, surface temperature, cloud fraction, precipitation, world topography/bathymetry, aerosol optical thickness, and biosphere (from different times of the year) with the goal of recognizing patterns and trends in …
What are the global and Indian patterns of biodiversity?
It says that the species richness increases as we go from poles to the tropics. But in deserts , Tropical region is rich in species diversity. For example – Columbia has 1400 bird species where as India has 1200 bird species. Moreover Tropical Forest has greater species diversity than temperate forest.
What 3 factors affect the biodiversity of an ecosystem?
Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches.
Which of the following factors contributes to the distribution of biodiversity on Earth?
Historically, habitat and land use change have had the biggest impact on biodiversity in all ecosystems, but climate change and pollution are projected to increasingly affect all aspects of biodiversity.
What are the major factors affecting biodiversity today which one currently has the greatest overall effect How is climate change different from the other factors?
Climate change, deforestation and loss of habitat and pollution are one of the factors affecting biological diversity. The greatest factor would be climate change wherein animals and other species fail to adapt in changing climate thus resulting to their death.
