Figure 1 shows how having multiple species present in a plant community can stabilize ecosystem processes if species vary in their responses to environmental fluctuations such that an increased abundance of one species can compensate for the decreased abundance of another.
What is diversity and stability?
The diversity-stability hypothesis states that ecosystems with greater species diversity are more stable. … There are more studies that support this hypothesis than those that refute it, but there is also a recognition that we need to understand the exact mechanisms in operation and that much remains understood.
What is meant by ecosystem stability?
Stability (of ecosystem) refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.
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 is ecological diversity and its types?
Ecosystem diversity deals with the study of different ecosystems in a certain location and their overall effects on humans and the environment as a whole. It is one of the types of biodiversity along with species diversity, genetic diversity, and functional diversity.
Which of the following is an example of ecosystem diversity?
Which of the following is an example of ecosystem diversity? Explanation: River ecosystem is an example of Ecosystem diversity. Rivers include fish, mussels, aquatic insects and a variety of planets. Ecosystem diversity explains the interaction between living organisms and physical environment in an ecosystem.
What is meant by the term ecological succession?
Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time. … The structure of this community becomes more complex as new species arrive on the scene.
What is ecosystem stability Why is it important?
Ecosystem stability is an important corollary of sustainability. Over time, the structure and function of a healthy ecosystem should remain relatively stable, even in the face of disturbance. If a stress or disturbance does alter the ecosystem is should be able to bounce back quickly.
Which ecosystem is most stable?
The ocean is the most stable ecosystem. It is stable due to its natural liquid nature (saline), dissolved oxygen, light and temperature. Note: An environment is considered to be stable when its structure and function remain unchanged for a long period of time.
What type of ecosystem is most stable?
Oceans is stable ecosystems since it stays unchanged over the long term. Various natural geological and anthropogenic forces build and damage mountains, deserts and forests but oceans have remained stable over the long history of the Earth.
Does diversity equal stability?
Viewpoint: Yes, greater species diversity does lead to greater stability in ecosystems. … Ecologists tend to focus their attention on species diversity, also known as biodiversity, within particular ecosystems, although ecosystems are always part of a larger continuum.
What is the diversity stability hypothesis?
The stability-diversity hypothesis states that the more diverse a community is, the more stable and productive the community is. This hypothesis was formed from the basis that more stable and productive communities can use their resources better and more efficiently as compared to communities of less diversity.
What is ecosystem diversity and why is it important?
Ecological diversity is a type of biodiversity. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. Biodiversity is important because it clears out our water, changes out climate, and provides us with food.
What are the three different types of ecological diversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
What is ecosystem diversity class 12?
(c) Ecological diversity is the diversity at ecosystem level. For example, India with its deserts, rain forests, mangroves, coral reefs, wetlands, estuaries and alpine meadows has a greater ecosystem diversity. 2. Global species diversity means total species present on the earth.
