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 is the greatest cause of biodiversity?
Habitat destruction, or change can limit number of species a habitat at will support. This is the greatest cause of biodiversity. … Species may become endangered or even extinct if they are trapped, hunted, or otherwise harvested faster that the species can reproduce and grow.
What are the main factors that affect biodiversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7). No single measure or indicator represents the totality of the various drivers.
What is the factor of biodiversity?
What 3 factors affect the biodiversity of an ecosystem? Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches.
Which environment is most likely to have the greatest levels of biodiversity?
The greatest biodiversity is found in the tropical regions of the world, particularly among tropical rainforests and coral reefs. Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction.
Where in a forest are you likely to find the greatest biodiversity?
Tropical rainforests are found right around the equator. Some argue that a uniform climate in regards to temperature is important for biodiversity. The amount of available energy or productivity is also thought to contribute to diversity, and tropical rainforests have a large amount of both.
What is the greatest threat to biodiversity?
Climate change was ranked as a 6% risk to Earth’s biodiversity. WWF’s Living Planet Report 2020 has ranked the biggest threats to Earth’s biodiversity. The list includes climate change, changes in land and sea use and pollution. The WWF used data from over 4,000 different species.
What is the greatest cause of biodiversity loss today explain?
Habitat alteration-every human activity can alter the habitat of the organisms around us. Farming, grazing, agriculture, clearing of forests, etc. This is the greatest cause of biodiversity loss today.
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 ecosystem likely has the highest biodiversity quizlet?
Large ecosystems always have higher biodiversity than smaller ecosystems. A large area of a forest will likely have higher biodiversity than a smaller area of the same forest. A half acre of rainforest would likely have greater biodiversity than a full acre of desert.
Which ecosystem has the greatest biodiversity?
Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest.
Why is the most biodiversity found near the equator?
There might be more biodiversity near the equator because it’s warmer year round, allowing organisms to continue growing. Locations away from the equator will have cold winters that will slow growth for microorganisms, plants and animals.
Which of the following has the greatest number of ecosystem?
Detailed Solution. The correct answer is Decomposers. Decomposers include micro-organisms such as bacteria and fungi.
