When an ecosystem has high biodiversity it is always more stable than an ecosystem that has low biodiversity. … 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 makes an ecosystem have high biodiversity?
High biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.
What is an example of high biodiversity and low biodiversity?
Examples of places with high biodiversity include rainforests and coral reefs, because they have many different species in an area. Less biodiverse areas include deserts, icy areas, and the bottom of the ocean.
Why is biodiversity high in some places and low in others?
Biodiversity is a variety of different species in a specific area. … number of different species and their abundance. Why is biodiversity high in some places but low in others? Because some areas have a lot of organisms that are only able to live in a limited or specific habitat.
What is an example of an ecosystem that has 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. Example of ecosystem with high biodiversity is tropical rain forest as seen in Amazon basin of south America.
What is the effect of high and low diversity in an ecosystem?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
What are some examples of ecosystems with high biodiversity?
Some examples of ecosystems that are rich in diversity are:
- Large marine ecosystems.
- Marine ecosystems.
- Old-growth forests.
- Coral reefs.
What is the difference between ecosystem that has a high index of diversity and an ecosystem that has a low index of diversity?
A high index value suggests a stable site with many different niches and low competition (high richness and evenness) A low index value suggests a site with few potential niches where only a few species dominate (low richness and evenness)
How can you tell if biodiversity is high or low?
Diversity is defined as the measure of the number of different species in a biotic community. Generally speaking, diversity is high when there are many different species in a community and and low when there are few.
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.
Explanation: Biodiversity is a measurement of how many different types of organisms are found in an ecosystem. The higher the biodiversity means that the ecosystem can sustain (maintain) many different types of producers, consumers, and decomposers. This generally means that the area is healthy.
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 happens when an ecosystem has 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.).
When would an ecosystem with high biodiversity tend to be more stable than an ecosystem with low biodiversity?
An ecosystem with a high level of species diversity such as a rainforest (high productivity) is much more stable than an ecosystem with low biodiversity such as a desert (low productivity). All ecosystems are complex and all species have a niche. Loss of any species can upset a whole food web.
