What types of organisms are r-selected. R selection a type of selection that favours organisms with a high biotic potential ( r value ). This is opposed to r selected species , which produce a lot of offspring but tend to invest relatively little energy in them. These types of organisms have very small offsprings but the number of offsprings will be more and these offsprings… view the full answer
The lowercase r is used to represent growth rate in ecological equations, and so is also used to represent species with a high reproductive rate. The young tend to be altricial (immature, requiring extensive care). What types of organisms are considered r selected?

This is opposed to r selected species, which produce a lot of offspring but tend to invest relatively little energy in them. They also have shorter lifespans and reach sexual maturity quickly. They tend to be smaller organisms, so the energy used to make each individual is low, and they live in unstable environments.
Bacteria oysters weeds mice rabbits jellyfish dandelions insects such as mosquitoes, house flies, daphnia and goldenrod. These species try to fill all available niches in an environment. K selected organisms produce few offspring but invest a lot of energy in them, and examples would include whales, primates (which includes humans), elephants, and some birds, like arctic terns.
Organisms that are r selected ( r strategists) are able to colonize a habitat rapidly, utilizing the food and other resources before other organisms are established and begin to compete. It has a high growth rate but low survivability. School miami dade college, north;
This species are with a capacity of high rate of population growth. In a nutshell, r selected populations are more “yolo” type while k selected populations are more “dig in and play for the future” type. There is no parental investment and they become reproductively active early in their.
