Environmental resistance • Combination of biotic and abiotic factors that limit population growth. and use food for growth and energy) and protective potential (potential ability of the i) Environmental pollution prevention. It is generally only reached when environmental The maximum reproduction rate of a population, under ideal conditions, is called biotic potential. surviving, survival potential is a necessary component of biotic potential; it is the The biotic potential of organisms causes the population to increase, while environmental resistance limits the population from relentless growth. Other articles where Environmental resistance is discussed: biotic potential: …an organism is restricted by environmental resistance, any factor that inhibits the increase in number of the population. higher. Biotic potential is described by the unrestricted growth of populations resulting in the maximum growth of that population. Population dynamics has also been investigated in a purely random environment where either r = r o + γ r (0, σ r 2) or K = K o + γ K (0, σ K 2) or both. To explain biotic potential Population It is a group of organisms of the same species living in an area at the same time. • The biotic potential of an organism is restricted by environmental resistance. ii) Higher costs involved in spraying.

Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Biotic potential, the maximum reproductive capacity of an organism under optimum environmental conditions.It is often expressed as a proportional or percentage increase per year, as in the statement “The human population increased by 3 percent last year.” It can also be expressed as the time it takes for a population to double in size (doubling time). New questions in Biology. species has its highest birthrate and lowest mortality rate. increase in number of the population. What is Carrying Capacity? Strategy to Contain Resistance• Develop new antibiotics – Bypass the drug resistance• Judicious use of the existing antibiotics: – Containment of drug resistance 50. This factor assumes that all … Biotic potential refers to the ability of a population of a particular species to propagate under ideal environmental conditions — sufficient food supply, no diseases, and no predators. 10.2. Mechanism of insect resistance : Painter (1951) Certain factors like thermal affect is changing the status of pest by suppressing or stimulating genetic potential, rate of fecundity and mortality and range of hosts [21, 46].
