What is the rivet popper hypothesis who had given this hypothesis?

Paul Ehrlich
‘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.

What is the redundancy hypothesis?

Redundancy hypothesis refer to the enhancement of species that can compensate each other if some species loss due to harsh conditions such particular species has the ability to recover from environmental disturbances.

What is the rivet model?

In the rivet model, an ecological function will not disappear until all the species performing that function are removed from an ecosystem. Overlap of ecological function enables an ecosystem to persist.

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 rivet popper hypothesis 12?

The Rivet Popper Hypothesis was proposed by Paul Ehrlich. The hypothesis suggests the importance of species richness in the maintenance of the ecosystem. The rivets of an aeroplane were compared with species in an ecosystem.

Which of the following loss of rivet will be more crucial?

According to The River Popper hypothesis, loss of rivets on the wings is obviously a more serious threat of flight safety than loss of a few rivets on the seats or windows inside the plane as which rivet is removed from the airplane may also be critical.

What is rivet in biology?

Definition. It is a theory that entails about the conditions of ecosystem wherein a significant loss of a certain species affects the functions and diversity of an ecological community. Supplement.

What is an example of functional diversity?

Some examples of functional diversity include the patterns of species co-occurrence, community assembly, and understanding species competitive abilities. The major role of this factor is to maintain important functions and services of ecosystems.

Why is biodiversity important?

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.

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.

What is primary and secondary succession?

Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is made of rock, devoid of soil.

What is the evil quartet class 11?

The devil or evil quartet is a sobriquet used to describe the four major causes that have led to the accelerated rate of extinction of species. These cause habitat loss and fragmentation, over-exploitation, alien species invasion and co-extinction.
