What is cascade in physics?

When an electron with an energy of the order of one GeV or more is introduced in matter, it radiates photons of comparable energy. Eventually, the energy of the original electron is divided in a “shower” or “cascade” (Fig. 1).

What is a cascade effect in biology?

An ecological cascade effect is a series of secondary extinctions that are triggered by the primary extinction of a key species in an ecosystem. When the prey’s food resources disappear, they starve and may go extinct as well.

What is an example of the cascade effect?

An example of the cascade effect caused by the loss of a top predator is apparent in tropical forests. When hunters cause local extinctions of top predators, the predators’ prey’s population numbers increase, causing an overexploitation of a food resource and a cascade effect of species loss.

What are the two types of cascade effect?

In conclusion, the cascade effect comes in two forms, bottom-up and top-down. Top-down is influenced by predation and relies on factors such as feeding behaviour and body-size of apex predators to show the typical positive/ negative changes in trophic structure when moving downwards.

How does cascade work MTG?

“Cascade” means “When you cast this spell, exile cards from the top of your library until you exile a nonland card whose mana value is less than this spell’s mana value. You may cast that card without paying its mana cost if the resulting spell’s mana value is less than this spell’s mana value.

What is a medical Cascade?

Cascade: A sequence of successive activation reactions involving enzymes (enzyme cascade) or hormones (hormone cascade) characterized by a series of amplifications of an initial stimulus. In blood coagulation, for example, each enzyme activates the next until the final product, the fibrin clot, is reached.

What is the opposite of a trophic cascade?

This contrasts to top-down cascading effects, in which the direction of the effects between adjacent trophic levels is generally opposite: an increase in the abundance of predators results in a decrease in herbivores and subsequently an increase in plant biomass (Pace et al. 1999).

What is cascading in C++ example?

When an object calls an operator function by passing an argument and the returned value of the operator function calls the next operator function in the same expression, it is called as cascading of operators.

Why do we use cascade?

CASCADE. It is used in conjunction with ON DELETE or ON UPDATE. It means that the child data is either deleted or updated when the parent data is deleted or updated. It means that the child data is set to NULL when the parent data is deleted or updated.

What is Cascade in magic?

Can you cascade into another cascade?

Because you cast the spells you Cascade into, you can then Cascade off of those spells etc. The only real limit is that you’re going down by at least CMC 1 every time you do it. So eventually you’ll run out of valid targets to Cascade into.

What is ecological cascade?

An ecological cascade effect is a series of secondary extinctions that is triggered by the primary extinction of a key species in an ecosystem.

What are trophic cascades?

Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when predators in a food web suppress the abundance or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate trophic level is a herbivore).

What is the definition of trophic cascade?

Trophic cascade, an ecological phenomenon triggered by the addition or removal of top predators and involving reciprocal changes in the relative populations of predator and prey through a food chain, which often results in dramatic changes in ecosystem structure and nutrient cycling.
