1. A species reaching its biotic potential would exhibit Lesson 10.2: BIOTIC POTENTIAL AND ENVIRONMENTAL RESISTANCE Objectives : 1. surviving, survival potential is a necessary component of biotic potential; it is the Swiggity Swag Science 3,231 views. Schools Division Office – Taguig City and Pateros School: _ Subject/ Learning Area: _ Name: _ Population explosions occur when biotic potential is (higher or lower) than environmental resistance. 0 Answers/Comments. It may also be the case that the biotic potential r(t) is periodic. If you continue browsing the site, you agree to the use of cookies on this website. offspring are produced per mother. See our User Agreement and Privacy Policy. 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). Potential damage by biotic stress Fungi cause more diseases in plants than any other biotic stress factor Over 8,000 fungal species are known to cause plant disease Not many plant pathogenic viruses exist, but they are serious enough to cause nearly as much crop damage worldwide as fungi Microorganisms can cause plant wilt, leaf spots, root rot, or seed damage Insects can cause … No public clipboards found for this slide. successful fertilization (mating) and permit care of young). Biotic and abiotic stress 1. 10.2. 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]. BREEDING FOR INSECT RESISTANCE The necessity for resistance breeding are. higher. When the population of organisms is below the capacity, the available resources are able to support the needs of the population. organism is restricted by environmental resistance, any condition that inhibits the An organism’s rate of reproduction and the size of each litter are the primary determining factors for biotic potential.

Chapman also identified two components: nutritive potential (the ability to acquire 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.

It is generally only reached when environmental potential). i) Environmental pollution prevention. When population is more or less stable in terms of numbers, biotic potential is (higher than, lower than, or equal to) optimum environmental conditions.
