What will happen to an ecosystem with low biodiversity?
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.).
What is an example of an ecosystem with low biodiversity?
Example of ecosystem with low biodiversity is definitely a desert. Then there are cold deserts in Antarctica and Gobi basin of central Asia, where biodiversity is minimum.
Which ecosystem has low biodiversity diversity?
Explanation: Estuarine areas (where rivers meet seas and oceans) have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity.
How would you describe the biodiversity of an ecosystem?
Ecosystem biodiversity refers to the variety of ecosystems, by their nature and number, where living species interact with their environment and with each other. For example, on Earth, there are different ecosystems, each with their specificities like deserts, oceans, lakes, plains or forests.
What is low diversity?
Firstly, low biodiversity means that the trophic system is likely less functional. Since there are less species in the various tropic levels, meaning the paths of energy and nutrients are fewer in number. High biodiversity is like a bed of nails, except the nails are what’s keeping the ecosystem alive.
What causes low 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.
Why is there a low species diversity in the desert?
Biodiversity is low in hot desert ecosystems. There are far fewer species supported by the extreme climate compared to other biomes. This is due to the high temperatures, low rainfall and a lack of available water. A small change in biotic or abiotic conditions can have a significant impact on the ecosystem.
What ecosystem has greater biodiversity?
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
What is low ecosystem?
It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment. A mown lawn in a city park is an example of an ecosystem with low biodiversity.
What factors affect biodiversity in an ecosystem?
Factors that affect biodiversity in an ecosystem include area, climate, and diversity of niches. Which human activities threaten biodiversity? Human activities can also threaten biodiversity. These activities include habitat destruction, poaching, pollution, and the introduction of exotic species.
Which of the following is not a cause 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.
Example of ecosystem with low biodiversity is definitely a desert. Then there are cold deserts in Antarctica and Gobi basin of central Asia, where biodiversity is minimum. Example of ecosystem with high biodiversity is tropical rain forest as seen in Amazon basin of south America.
What is the difference between low biodiversity at the equator?
At the polar regions, low biodiversity is found. It is due to low temperature. The temperature fall below the zero degree. So, it leads to low biodiversity. On the whole we can say that the biodiversity decreases from the equator to the poles, while the reverse situation is found from the polar regions to the equator.
What is the definition of biodiversity in geography?
Biodiversity can also refer to the variety of ecosystems—communities of living things and their environments. Ecosystems include deserts, grasslands, and rain forests. The continent of Africa is home to tropical rain forests, alpine mountains, and dry deserts. It enjoys a high level of biodiversity.
Which regions have the most and least biodiversity?
Tropical regions, areas that are warm year-round, have the most biodiversity. Temperate regions, which have warm summers and cold winters, have less biodiversity. Regions with cold or dry conditions, such as mountaintops and deserts, have even less.
