how does species richness affect an ecosystem?

Increased species richness does not always cause increased ecosystem function. Instead, richness can influence individual species with positive or negative ecosystem effects. ... It is also diluted from species-poor communities, allowing yeasts with lower functional impacts to dominate.

Biodiversity is a very important factor for ecosystem health because having a variety a species helps ensure that, should a disaster happen, certain species will not go extinct. ... Shannon Diversity index (H) is used to calculate the biodiversity of an ecosystem. The higher the number is, the more diverse that habitat is.

Answer and Explanation: One biotic factor that affects the size of a population in an ecosystem is the number and type of predators in that ecosystem.

The idea that natural communities rich in species are healthier and more productive has been an axiom in ecology for decades. ​Biodiversity has been hypothesized to maintain the stability of natural ecosystems and provide benefits such as oxygen, soils, and water detoxification. ...

Ecosystems with higher biodiversity are more stable as they can easily adjust to changes. We are slowly realising that the future of our species on Earth depends on maintaining high biodiversity. Biodiversity is important for human wellbeing as it provides food, potential foods, industrial materials and new medicines.

1 Answer. Number of species per unit area is called Species Richness. If you have more number of species , more will be species richness hence stable will be the ecosystem. More species richness will contribute to increase in biodiversity also which is an important aspect biodiversity conservation.

We find that there is indeed a relationship between the land area and species richness of a region once tropical species are excluded. This relationship is independent of the latitude and productivity of regions. Both latitude and productivity can explain variance in richness unexplained by land area.

Generally speaking, greater species diversity (alpha diversity) leads to greater ecosystem stability. This is termed the "diversity–stability hypothesis." An ecosystem that has a greater number of species is more likely to withstand a disturbance than an ecosystem of the same size with a lower number of species.

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.

The biodiversity of an ecosystem contributes to the sustainability of that ecosystem. Higher/more biodiversity = more sustainable. Lower/less biodiversity = less sustainable. High biodiversity in an ecosystem means that there is a great variety of genes and species in that ecosystem.

Biodiversity promotes ecological resilience, so that a system might have a higher chance of surviving disturbances. The more biodiversity there is in a system, the more likely that system is to absorb some manner of destructive event and still return to a stable state.

Biodiversity occurs in three different levels: Genetic, Species, and Ecosystem. Genetic diversity refers to the differences within members of a species and their ability to adapt to changes. ... Ecosystem refers to the specific natural communities and the diverse species found there.

Dominant species are the most abundant species in a community, exerting a strong influence over the occurrence and distribution of other species. In contrast, keystone species have effects on communities that far exceed their abundance.

Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.
