The Productivity Hypothesis says that the more energy there is in a system, the more biomass there will be in that system. More biomass supports greater species diversity. The main idea behind this hypothesis is that larger animals have relatively slower metabolic rates when compared to smaller animals.

Biodiversity is a measure of the complexity of interactions in a given habitat or ecosystem. Ecological productivity is a measure of the rate of generation of biomass or carbon per area of habitat or ecosystem. The more biomass (living organisms and organic matter) produced, the greater the productivity.
What is suggested by the productivity stability hypothesis of species diversity?
New insights from recent studies support the hypothesis that species diversity enhances productivity and stability in some ecosystems, but not in others. Appreciation is growing for the ways that particular ecosystem features, such as environmental variability and nutrient stress, can influence biotic interactions.
Why does productivity increase with species richness?
If this happens, the effect of increasing species richness on productivity is attributed simply to the increased odds of encountering species particularly well adapted to the environment.
What is the ecology hypothesis?
“Ecosystem Core” hypothesis is an innovative explanation of ecosystem evolution, which is related to but distinct from the theory of community succession. Natural energy is the basic force for sustaining ecosystem development, and artificial energy input is the direct cause of ecosystem evolution.
What is productivity in an ecosystem?
In ecology, production (or productivity) refers to the rate of generation of biomass in an ecosystem. It is usually expressed in units of mass per area per time (e.g. kg m –2 day –1)
Which of the following ecologist gave rivet popper hypothesis?
‘Rivet popper hypothesis’ was proposed by Paul Ehrlich. According to this hypothesis in an airplane, all parts are joined together using thousands of rivets similarly in the ecosystem all are joined together by thousands of species.
Why is a less biodiverse than B?
when only a few species inhabit an area. when only one organism (plants and animals) is found living in one area. Why is “A” less biodiverse than “B”? Even though “A” has a lot of corn plants they are all the same species and makes this a low “poor” biodiverse area.
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 stability in biology?
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.
How does productivity increase in ecosystem?
On land, it is driven by temperature and availability of water and nutrients modified by land use. In aquatic ecosystems, primary productivity is driven by the availability of nutrients and light and, to a lesser extent, by temperature and other factors.
What is your productivity?
Productivity is a measure of efficiency of a person completing a task. We often assume that productivity means getting more things done each day. Productivity is getting important things done consistently. And no matter what you are working on, there are only a few things that are truly important.
How does productivity affect diversity?
A common pattern emerging from studies on the relationship between plant diversity and ecosystem functioning is that productivity increases with diversity. The question whether interactions between few species or among many species lead to increased productivity remained largely unanswered.
What is scientific hypothesis example?
For example, a scientist can form a hypothesis that a certain type of tomato is red. During research, the scientist then finds that each tomato of this type is red. Though his findings confirm his hypothesis, there may be a tomato of that type somewhere in the world that isn’t red.
What is the scientific hypothesis?
A hypothesis is an idea or proposition that can be tested by observations or experiments, about the natural world. In order to be considered scientific, hypotheses are subject to scientific evaluation and must be falsifiable, which means that they are worded in such a way that they can be proven to be incorrect.
How do you write a hypothesis for ecology?
You will need to state a functional hypothesis that is phrased to include a cause and effect relationship. For example, you might state your hypothesis as “if oaks are the dominate tree species in an area, then gray squirrels will be the more abundant than in areas dominated by pines”.
