Question: Why is a high species diversity considered good for ecosystems?

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 is species diversity good for ecosystems?

Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. … A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.

Is high species diversity good?

On the other hand, high species diversity could suggest that there is a large number of successful species and a more stable ecosystem than the low value habitat, there is a complex food web and environmental changes are less likely to be damaging to the ecosystem.

What is an ecosystem with high biodiversity?

Example of ecosystem with high biodiversity is tropical rain forest as seen in Amazon basin of south America. Such forests are also thriving in parts of central Africa and also in islands of Indonesia. In marine environment, coral reefs are example of high biodiversity aquatic ecosystems.

What does a high species diversity mean?

Species diversity is a measure of community complexity. It is a function of both the number of different species in the community (species richness) and their relative abundances (species evenness). Larger numbers of species and more even abundances of species lead to higher species diversity.

Why is species diversity a better measure than species richness?

Species diversity is a measurement of species richness combined with evenness, meaning it takes into account not only how many species are present but also how evenly distributed the numbers of each species are. … Because it was more evenly distributed, community two would have a greater species diversity.

Why is high biodiversity advantageous over low biodiversity?

High biodiversity is advantageous over low biodiversity because ecosystems with high biodiversity are better able to remain at homeostasis and be…

Which ecosystem would have a higher diversity value?

Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes. Net primary productivity ranges from 2–3 kg m2 y1 or higher.

What is species diversity used for?

Species diversity is a benchmark that can be used to evaluate the health of ecosystems. In a healthy ecosystem, a diverse and balanced number of species exist and maintain the equilibrium of the ecosystem.
