: the sum of the environmental factors (such as drought, mineral deficiencies, and competition) that tend to restrict the biotic potential of an organism or kind of organism and impose a limit on numerical increase.
What are some examples of environmental resistance?
Environmental resistance factors are things that limit the growth of a population. They include biotic factors – like predators, disease, competition, and lack of food – as well as abiotic factors – like fire, flood, and drought.
How does environmental resistance affect population growth?
Environmental Resistance can reduce the reproductive rate and average life span and increase the death rate of young. As Environmental Resistance increases, population growth slows and eventually stops, likely near (k).
What is environmental resistance in entomology?
Environmental resistance is the physical and biological restraints that prevent a species from realizing its Biotic potential.
Why is a pregnant woman a biotic potential?
Is a pregnant woman a biotic potential? To reach its biotic potential, all females would have to become pregnant every nine months or so during their reproductive years. Also, resources would have to be such that the environment would support such growth.
What are the three biotic potential and environmental resistance presented in the story give example of each?
Biotic factors include predation, competition, parasitism, and diseases. Abiotic factors include climatic conditions, fire, and temperature. Some of the common examples of environmental resistance include the availability of water and predator-prey relationship.
How would environmental resistance affect the survival of an organism?
Environmental resistance are factors that limit the biotic potential of an organism. It includes abiotic and biotic factors. … Biotic potential of organisms makes the population increase while environmental resistance limits the population on growing relentlessly.
What is environmental resistance how it can be represented mathematically?
The term ‘(K-N)/K’ in the equation for logistic population growth represents the environmental resistance, where K is the carrying capacity and N is the number of individuals in a population over time.
Which of the following is an example of environmental resistance quizlet?
Environmental resistance is environmental factors such as: droughts and competitions. It can restrict the biotic potential of organisms and not let them increase. Droughts and competition can both cause death thus decreasing the population of the organisms.
What makes an organism resistant to a chemical?
An organism may be resistant to a chemical when it contains a gene that allows it to break the chemical down into harmless substances. … The survivors happen to have a gene that protects them from the pesticide. The surviving insects pass on the gene to their offspring.
What is meant by insect ecology?
Insect ecology is the scientific study of how insects, individually or as a community, interact with the surrounding environment or ecosystem.
What is the greatest problem that the human population will face if we fail to have a greater understanding of ecology and environmental science?
the carrying capacity. the carrying capacity. What is the greatest problem that the human population will face if we fail to have a greater understanding of ecology and environmental science? We will have a lack of understanding about the problems that the human population poses to the health of the biosphere.
What will cause the human population to go down?
A reduction over time in a region’s population can be caused by sudden adverse events such as outbursts of infectious disease, famine, and war or by long-term trends, for example sub-replacement fertility, persistently low birth rates, high mortality rates, and continued emigration.
Is the human population increasing or decreasing?
Population growth is the increase in the number of people in a population. Global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020.
