Why is a pond a self-sustaining unit while an aquarium may no be so?
Since a pond is a natural ecosystem, it has all the biotic and abiotic components in it and these components are interlinked with eachother for ensuring the survival of the organisms there, hence its a self sustaining unit. Where as, an aquarium is an artifitial ecosystem, it is made by man. So, if any fish or other organisms present in the aquarium die, its dead body will not be acted upon by decomposers cause of its absence. Also there is no sunlight and other abiotic factors, so the survival of the organisms in the aquarium is to be relied upon man who has to ensure the maintenance of the aquarium , so the aquarium is not a self-sustaining unit.
Substances that enter a reaction are termed?
A substance which enters into a chemical reaction is called a reactant.In a chemical reaction-also called chemical change- one or more reactants (the initial substances that enter into the reaction) change into one or more products (the final substances that are present at the end of the reaction).
A reaction that releases energy in the form of heat?
An exothermic reaction releases energy in the form of heat. This type of reaction typically results in a rise in temperature in the surrounding environment. Examples include combustion and neutralization reactions.
When two sugars are combined a water molecule is lost This process is called?
Dehydration Synthesis, also called a condensation reaction, a dehydration reaction or just condensation.
Is this a closed or open ecosystem?
Without additional context, it is difficult to determine. Closed ecosystems are self-sustaining, with minimal exchange of matter with the external environment. Open ecosystems have exchange with the external environment.
What is it called when neutrons released from a fission event cause other fission events in a continued self sustaining cascade?
This process is called a nuclear chain reaction. Neutrons released from one fission event trigger other fission events, creating a self-sustaining reaction that releases energy and more neutrons, continuing the chain reaction.
What is it called when nuclear fission is repeated?
It is called nuclear chain fission reaction.
The smallest amount of a fissionable material that will give a self-sustaining chain reactions is called the?
The smallest amount of a fissionable material that will produce a self-sustaining chain reaction is called the critical mass. This mass of affected by geometry and other factors such as temperature, pressure, and moderator.
A Self-sustaining nuclear fission chain reaction is dependent upon the release of what?
Neutrons
What is the name of a glider plane designed for sustained flight called?
self sustaining sailplane
What is caused when critical mass is reached?
When critical mass is reached, a self-sustaining chain reaction occurs, leading to a nuclear explosion in the case of nuclear fission. In social contexts, critical mass refers to the point at which a movement or idea gains enough momentum to be self-sustaining and bring about significant change.
Why is fission reaction called chain reaction?
A fission reaction is called a chain reaction because the initial splitting of an atomic nucleus releases neutrons that can go on to split other nuclei, creating a self-sustaining "chain" of reactions. This process continues exponentially, leading to a release of energy.
What is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor
Which is the called living things?
Living things refer to anything with self-sustaining biological processes.
What is the process in which one initial reaction triggers a growing number of subsequent reactions?
That process is called a chain reaction. In a chain reaction, the products of one reaction act as reactants in the subsequent reactions, leading to a self-sustaining series of reactions. This can result in a rapid release of energy, as seen in nuclear reactions or certain chemical reactions.
What do you mean when you say the fission needs to be self-sustaining?
What you look for in a NPP is a self-sustaining chain reaction, where the original fission releases enough neutrons to cause the rest of the fuel to undergo fission without continuously having to bombard it with more neutrons. But, you don't want the reaction to be uncontrolled - to happen too fast to be able to harness the energy. That is what happens with atomic bombs.
What do you call anything that can live on its own?
it is called a self-sustaining being I believe.
