What is the difference between R and K selective?
r-selected babies grow rapidly, and tend to be found in less competitive, low quality environments.
K-selected species produce offspring that each have a higher probability of survival to maturity..
What is r at carrying capacity?
In the equations describing growth of populations of organisms, r represents the slope of the line representing exponential growth. The letter K represents the carrying capacity of a habitat for members of a given sort of organism.
Are bacteria R selected?
R-selected organisms, those emphasizing a fast growth rate, high number of offspring, include rabbits, bacteria, salmon, plants such as weeds and grasses, etc.
Why are rabbits r selected species?
So this begs the question are rabbits truly prolific, and why? In Page 2 the 1960s two ecologists came up with r/K selection theory. It relates to parental investment and reproductive strategies adopted by species in order to advance its kind into the future. … And they have the ability to reproduce rapidly.
Are birds r selected species?
In this equation N is the number of individuals in the population, t is time, and r is the biotic potential. Examples of K-selected species include birds, larger mammals (such as elephants, horses, and primates), and larger plants.
Are cats R strategists?
r selected species are also known as r strategists and opportunistic species. They practice big-bang reproduction, AKA semelparity. … Cats are r-selected compared to humans, and K-selected compared to cockroaches.
Are humans R-selected or K-selected?
Elephants, humans, and bison are all k-selected species. … These species often have short life expectancies, produce as many offspring as they can, and invest very low amounts of parental care. R-selected species can include mosquitos, mice, and bacteria.
What are examples of R-selected species?
Typical examples of r-species are mice, rabbits, weeds and bacteria, which have a lot of offspring, but a short life expectancy. Examples of organisms undergoing K-selection are tortoises, elephants, people, and sequoia trees: their offspring are few but long-lived.
What characteristics do humans share with R-selected species?
Explanation: Species with r strategies are characterized by favoring a high population growth rate, The humans share this characteristic because the population increase has been exponential worldwide more than 7550 millions of habitants.
Are trees R or K-selected?
For instance, trees have traits such as longevity and strong competitiveness that characterise them as K-strategists. In reproduction, however, trees typically produce thousands of offspring and disperse them widely, traits characteristic of r-strategists.
Are Lions K-selected?
Common examples of k-strategists species include humans, lions and whales.
Are dogs r selected species?
Indeed, one can think of a given organism as an “r-strategist” or a “K-strategist” only relative to some other organism; thus statements about r and K selection are invariably comparative. Cats and dogs are r-selected compared to humans, but K-selected compared to mice and rats.
