Quick Answer: Which Organism Has The Highest Production Efficiency?

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 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.

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).

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 primary production and examples?

Primary production: this involves acquiring raw materials. For example, metals and coal have to be mined, oil drilled from the ground, rubber tapped from trees, foodstuffs farmed and fish trawled. … It involves converting raw materials into components, for example, making plastics from oil.

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.

What is production efficiency in biology?

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 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 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 net production efficiency?

Net production efficiency (NPE) measures how efficiently each trophic level uses and incorporates the energy from its food into biomass to fuel the next trophic level.

What is assimilation efficiency?

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.

What is primary production?

Primary production is when plants make their own food and use that food to live and grow. These plants do not depend on other plants, animals, or insects for their food. They can make their own with help from the sun, water, and air. Common primary producers in a schoolyard ecosystem are: grass.
