Why is production efficiency higher in poikilotherms?

Efficiency within a trophic level 5. Production Efficiency is the ratio of P to A. In poikilotherms more A goes to P in short lived species (<2yrs) because less is needed for R in nonreproductive periods, i.e. they have higher growth efficiency.

What is the difference between Homeotherms and poikilotherms?

homeotherm: An animal that maintains a constant internal body temperature, usually within a narrow range of temperatures. poikilotherm: An animal that varies its internal body temperature within a wide range of temperatures, usually as a result of variation in the environmental temperature.

Who has greater production efficiency poikilotherms or Homeotherms?

Abstract. The idea that homeothermic populations have a much lower production efficiency than poikilothermic populations, because warm-blooded individuals exhibit a higher metabolic rate per gram of body weight, is widespread. Therefore, their production efficiency as an adult is low.

What is the difference between ectothermic and poikilothermic?

As adjectives the difference between poikilothermic and ectothermic. is that poikilothermic is (of an animal) having a body temperature that varies depending on the outside temperature while ectothermic is of, or relating to an ectotherm; cold-blooded.

Are Homeotherms are always larger than poikilotherms?

Poikilotherm animals must be able to function over a wider range of temperatures than homeotherms. As a result, poikilotherms often have larger, more complex genomes than homeotherms in the same ecological niche.

Why is the production efficiency of Homeotherms lower than for Ectotherms?

What is the difference between cold-blooded and warm blooded?

Cold-blooded animals can be defined as animals that cannot regulate their internal body temperature with the change in the environment. Warm-blooded animals are defined as animals that can regulate and maintain constant internal body temperature. They can survive in any temperature range as they can adapt to it easily.

What are homeotherms and Heterotherms?

Homeotherms: animals who maintain a constant internal body temperature across a wide range of environmental conditions. Heterotherms: animals which usually keep a constant body temperature, but have specific periods where their temperature is different, such as during hibernation. We said most mammals were homeotherms.

What is the difference between ectothermic and endothermic?

An ectotherm (reptile/amphibian) relies primarily on its external environment to regulate the temperature of its body. Endotherms (birds) are able to regulate their body temperatures by producing heat within the body.

What are homeotherms mention an example?

Homeotherms are those organisms, that maintains the internal body temperature under the influence of variable environmental conditions through their metabolic activities like shivering, sweating. Mammals and birds are homeotherms.

Why is the production efficiency of homeotherms lower than for ectotherms?

What is production efficiency?

Production efficiency is an economic term describing a level at which an economy or entity can no longer produce additional amounts of a good without lowering the production level of another product.
