Why is it good to have high biodiversity?
Biodiversity is important to humans for many reasons. … 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.
Is it better to have low or high biodiversity and why?
Biodiversity is the number of species found within a habitat or an ecosystem. When an ecosystem has high biodiversity it is always more stable than an ecosystem that has low biodiversity.
What are the advantages of low biodiversity?
Advantages of low diversity are as follows: Organisms have less pressure for food requirements. Low diversity reduces the number of threatening predators.
Is a higher biodiversity better?
Summary: Ecosystems with high biodiversity are more productive and stable towards annual fluctuations in environmental conditions than those with a low diversity of species. They also adapt better to climate-driven environmental changes. … The loss of species diversity affects important ecosystems on which humans depend.
How does high biodiversity affect an ecosystem?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
Does it have high low biodiversity?
High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment.
Why do deserts have high biodiversity?
This is due to the high temperatures, low rainfall and a lack of available water. However, biodiversity increases close to desert water sources such as seasonal rivers and lakes and near to an oasis. … Some plants have the bulk of their biomass below the surface of the Earth where temperatures are cooler.
What place most likely 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.
What are the advantages and disadvantages of high biodiversity over low biodiversity in maintaining the stability of an ecosystem?
It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. Areas with high levels of species and genetic diversity are likely to have a more complex ecosystem, with a variety of food webs and biotic interactions.
