Biodiversity is the number of species found within a habitat or an ecosystem. … Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.
What is a biodiversity ecosystem?
Biodiversity is all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.
What is the meaning of 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 will happen to 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.).
Which ecosystem has high biodiversity low biodiversity?
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. Deserts, for example, contain limited numbers of species.
What are the 3 types of biodiversity?
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 is biodiversity example?
It is the biodiversity at the most basic level. It includes all the species ranging from plants to different microorganisms. No two individuals of the same species are exactly similar. For example, humans show a lot of diversity among themselves.
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.
What places have low biodiversity?
The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round. However, life does exist in the arctic regions, mostly affiliated with the seas that surround them.
Which one of the following has lowest biodiversity?
The tundra is the biome with the least biodiversity.
Why is high biodiversity advantageous to low biodiversity?
How does biodiversity affect sustainability? The higher the biodiversity of an ecosystem, the more sustainable it is. Conversely, lower biodiversity equals less sustainability. … The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem.
What is biodiversity important to ecosystem?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. … Our tourism industry also depends on biodiversity .
What is example of low biodiversity?
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. There will be two or three kinds of grasses, some dandelions, of course, and maybe a robin or some starlings poking about for worms or bugs.
Is the rice field an example of a low biodiversity ecosystem or a high biodiversity ecosystem?
The rice field has a surprisingly great biodiversity, perhaps the greatest of any tropical rainfed system, where Heckman (1979) recorded a total of 589 species of organisms in a rice field in Thailand.
Which among the three ecosystem has high 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.
