frogs are r-selected because they produce many offspring but only a few of them survive. There is no parental investment and they become reproductively active early in their life cycle.

Are vultures r selected or k selected?
Vultures are k-selected organisms because they only have a few offspring, they take care of their offspring, and they do not reproduce quickly.
Is an iguana r selected Or k selected?
k selected
Is Miami blue butterfly K-selected or R-selected?
K selected
Are whales r selected organisms?
no
What is the difference between r selected and k selected species?
R- Selected species have high population densities while k-selected species have lower population densities
What is the difference between r selected and K selected species populations?
Those are reproductive strategies that identify certain species. R-selected are those that reproduce rapidly and produce a lot of progeny; bacteria are an example. K-selected are those that reproduce very slowly and are slow to mature; humans are a k-selected species. Population density is the number of organisms per unit area. Some organisms don' t like to be crowded, so the density can affect the population size. Also, some limiting factors are density-dependent, like food or living space.
Is a sperm whale r-selected or k-selected species?
K-selected
Are grasshopper r-selected organism?
Grasshoppers are R-selected organisms. R-selected organisms are said to have a high ability to reproduce. They should also have a small body size, early maturity, a short generation time, and a wide offspring dispersion.

Are snakes r selected species or k selected species?
Snakes display both r and K traits. They are much longer lived, produce a moderate number of eggs (some species far fewer than others). The issue with the r/K equation is that there are too many species that have the characteristics of both the r and K types which renders the information either obvious...like humans being a definite K to some frogs that are definitely r...or with some calculated value that is essentially too general for use.
How can a stressful environment alter the standard r-selection and k-selection?
1. What is the difference between r-selected and k-selected organism? Which strategy would you expect to be more prevalent in unpredictable environments (high stochastic variation in conditions)?
What do you mean by 'r' and 'k' selection differentiate?
The r and K selection theory refers to two different reproductive strategies in ecology. r-selected species typically have many offspring, grow quickly, and have a high reproductive rate. K-selected species have fewer offspring, invest more resources in each offspring, and have a lower reproductive rate. These strategies are shaped by different environmental conditions and life history traits.
