Just as species have geographic ranges, they also have tolerance ranges for the abiotic environmental conditions. In other words, they can tolerate (or survive within) a certain range of a particular factor, but cannot survive if there is too much or too little of the factor.
How ranges of tolerance affect the distribution of a species?
Unfavorable abiotic and biotic factors can get a species out of its range of tolerance to the zone of physiological stress or zone of intolerance. … So, a species can only survive in the place where it can be within the tolerance range. Thus, ranges of tolerance affect the distribution of species.
How does an organism’s tolerance affect its niche?
An organism near the tolerance limits for one factor will probably be under stress, so its ability to tolerate other factors will be reduced. The tolerance ranges for environmental factors partly define the organism’s niche. If salinity tolerance is graphed against temperature tolerance, a niche area is defined.
What is an organism’s range of tolerance?
Printer-friendly version PDF version. The range of conditions within which an organism is potentially able to survive. For example, all organisms have a maximum and minimum level of temperature, atmospheric pressure, oxygen concentration etc. within which they can survive.
What is Habitat tolerance?
We should quickly touch on the range of tolerance in biology, which is defined as the range of environmental conditions that are tolerable for survival in a species. In other words, too little or too much of a specific environmental condition may result in death.
What determines the limits of tolerance of an organism?
The upper and lower limits to the range of particular environmental factors (e.g. light, temperature, availability of water) within which an organism can survive. Organisms with a wide range of tolerance are usually distributed widely, while those with a narrow range have a more restricted distribution.
Which of the following is most likely to occur if an organism’s environment is outside the organism’s range of tolerance?
What of the following is most likely to occur if an organism’s environment is outside the organism’s range of tolerance? The growth of the organisms increases.
What is the difference between tolerance range and optimal range?
Distinguish between tolerance range and optimal range. Tolerance range is the range of environmental conditions that are tolerable for survival in a species. Optimum range exists within the tolerance range and is smaller. The optimum range is ideal conditions for optimum growth and survival.
What is the relationship between tolerance range and limiting factors?
Just as species have geographic ranges, they also have tolerance ranges for the abiotic environmental conditions. In other words, they can tolerate (or survive within) a certain range of a particular factor, but cannot survive if there is too much or too little of the factor. Take temperature, for example.
What is the niche of an organism and how is it different from the organism’s habitat?
A habitat is the place where an organism lives while a niche is that organism’s role within that environment.
Why is it important for species to be in their optimum ranges?
Conditions that are most favorable for an organism to survive, grow and reproduce. This optimum is somewhere WITHIN the RANGE OF TOLERANCE for that organism. If an animal has a range of tolerance for temperature of 0-85 degree F somewhere within that temperature range will be the temperature that the animal grows BEST.
What is optimal range in biology?
Apart from pH, another factor that has optimum ranges for enzymes and living organisms is temperature. Similar to optimum pH, an optimal temperature would be one that is best or the most favorable to enzymatic activity and to the growth of living organisms. Word origin: Latin optimus (best, very good)
