Quick Answer: Which Group Has The Highest Production Efficiency?

What is the meaning of production efficiency?

Production efficiency refers to a level of production at which additional quantities cannot be produced without sacrificing the production of another product.

It is the level at which the maximum production capacity has been reached..

What is an animal’s assimilation efficiency?

assimilation efficiency, Assimilation efficiency is the percentage of food energy taken into the guts of consumers in a trophic compartment (In) that is assimilated across the gut wall (A„) and becomes available for incorporation into growth or to do work.

Which type of organisms will have the lowest production efficiency?

endothermic animals have a much lower production efficiency because they devote more energy to metabolism instead to producing more biomass.

Why is production efficiency higher for fishes?

Why is production efficiency higher for fishes than for birds and mammals? Much of a bird or a mammal’s assimilated energy is used to maintain a warm body temperature and is not available for net secondary production (growth and reproduction). Sewage and fertilizer pollution can add large amounts of nutrients to lakes.

What happens to the other 90% in the 10% rule?

Ten Percent Rule: What happens to the other 90% of energy not stored in the consumer’s body? Most of the energy that isn’t stored is lost as heat or is used up by the body as it processes the organism that was eaten.

What is production efficiency?

Production efficiency is an economic term describing a level in which an economy or entity can no longer produce additional amounts of a good without lowering the production level of another product. … Productive efficiency similarly means that an entity is operating at maximum capacity.

What is trophic efficiency?

Trophic efficiency The ratio of production at one trophic level to production at the next lower trophic level. is calculated by the percentage of energy that consumers in one trophic level gain and convert into biomass from the total stored energy of the previous trophic level.

What is net production efficiency?

net production efficiency (NPE): measure of the ability of a trophic level to convert the energy it receives from the previous trophic level into biomass.

What is the most efficient organism?

The tiny single-celled, plantlike organisms known as algae are more efficient than other organisms at converting sunlight and carbon dioxide into the raw materials needed for foods, products and fuels. And not just a few specialized fuels.

What is assimilated energy?

The assimilated energy is the efficiency of animals to convert the ingested food to the energy required for growth and reproduction. The production energy includes energy used for growth and reproduction. … The consumed energy is the total of assimilated and egested energies.

Which animal would have the highest production efficiency?

Plants have the greatest net production efficiencies, which range from 30-85%. The reason that some organisms have such low net production efficiencies is that they are homeotherms, or animals that maintain a constant internal body temperature (mammals and birds).

Which organism is most likely to have the highest assimilation efficiency?

HerbivoresHerbivores assimilate between 15 and 80 percent of the plant material they ingest, depending on their physiology and the part of the plant that they eat. For example, herbivores that eat seeds and young vegetation high in energy have the highest assimilation efficiencies,…

What is production efficiency in ecology?

Production in Production Efficiency is the storage of biomass and efficiency is that fraction of biomass consumed that actually ends up being stored, i.e., stored as an organism’s body, minus that amount lost as feces. …

What 3 ecosystems have the lowest productivity?

The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.

How do you calculate trophic efficiency?

What is the efficiency of this transfer? To complete this calculation, we divide the amount from the higher trophic level by the amount from the lower trophic level and multiply by one hundred. That is, we divide the smaller number by the bigger one (and multiply by one hundred).
