How can having more species make an ecosystem more sustainable?

The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

Why is it better to have more species in an ecosystem?

Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.

How can an ecosystem be more sustainable?

There are three main components required for sustainability in an ecosystem:

  1. Energy availability – light from the sun provides the initial energy source for almost all communities.
  2. Nutrient availability – saprotrophic decomposers ensure the constant recycling of inorganic nutrients within an environment.

How will increase species diversity affect ecosystem?

Explanation: By increasing species diversity in an ecosystem, both the efficiency and the productivity of an ecosystem will increase. A greater species richness and diversity may cause ecosystems to function more efficiently and productively by making more resources available for other species.

How does greater species diversity contribute to ecosystem stability?

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.

Why should we care about sustaining species and ecosystem services?

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. … Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.

What is the role of species in an ecosystem?

Key Concept Any given species may play one or more of 5 important roles – native, nonnative, indicator, keystone, or foundation – in a particular ecosystem.

Why do ecosystems need to be sustainable?

Our definition of ecological sustainability

Conserve the productivity of the waters, the soil and the ecosystems on a long-term basis. Reduce our impact on the natural environment and people’s health to a level that the natural environment and humanity can handle.

Which ecosystem is likely the most sustainable?

The forest ecosystem is most sustainable because most of the animals can eat other organisms. The food webs below model relationships among organisms in two ecosystems.

How does biodiversity affect the sustainability of an ecosystem?

The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

How is biodiversity related to ecosystem stability and sustainability?

It has been shown that biodiversity of an area has a large impact on the ecosystem stability of that area. … This increase in complexity makes it more likely that the ecosystem will return to a stable state after a disturbance, because the ecosystem has more ways to respond to a disturbance and fix problems.

How species diversity increases the probability of adaptation and survival of organisms?

Explanation: Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.
