What is the difference between a k- and r-strategist species?

Explanation:

difference between a k- and r-strategist species

R-selected species survive in variable and unstable environments, whereas K-selected species live in stable situations. R-selection species produce several common offspring whereas K-selection species produce few rare offspring. R strategist is an organism undergo fast reproduction to sustain themselves as they in the variable environment whereas K strategist is an organism that does not need to undergo fast reproduction as they live in stable conditions.

Ithink the dna sequences may vary but the amino acid sequences are identical.
