all biotic factors that affect the size of a population in a specific area
Biotic factors like organisms of other species living in the same area affect the population, as they involve in different types of food relationships. Different populations have different ability to tolerate changes in weather, physico-chemical and biotic factors. Biotic factors within a community can affect the populations of organisms but are also essential to the balance of life within the ecosystem. Examples of Biotic Factors: 1. Competition for food is an example of a biotic factor in an ecosystem. Abiotic factors vary in the environment and determining the types and numbers of organisms that exist in that environment. Factors which determine the types and numbers of organisms of a species in an ecosystem are called limiting factors. Many limiting factors restrict the growth of populations in nature. Biotic factors like organisms of other species living in the same area affect the population, as they involve in different types of food relationships. Different populations have different ability to tolerate changes in weather, physico-chemical and biotic factors. This is called resilence. Abiotic factors vary in the environment and determining the types and numbers of organisms that exist in that environment. Factors which determine the types and numbers of organisms of a species in an ecosystem are called limiting factors. Biotic Factors Examples. Biotic Factors. Biotic factors affect populations of organisms. This is a term that is used in the study of ecology. The word root bio- means life, therefore a biotic factor is any activity of a living organism that affects another living organism within its environment. Other conditions may lead to a species’ decline or even extinction. Both abiotic and biotic factors determine where a species can live. A limiting factor is any factor that places an upper limit on the size of a population. Examples of Biotic Factors: 1. Competition for food is an example of a biotic factor in an ecosystem. A red squirrel and a grey squirrel living in the same habitat will compete for the same food source. 2. Abiotic factors, such as temperature, soil and light, can also influence an organisms success in an area. The tolerance range of an organism are the abiotic conditions in which an organism can survive. At both the high and low ends of the tolerance range an organism is stressed. Answers: Biotic Factors Biotic, meaning of or related to life, are living factors. Plants, animals, fungi, protist and bacteria are all biotic or living factors. Abiotic Factors Abiotic, meaning not alive, are nonliving factors that affect living organisms.
