What is the primary characteristic of R-selected species?

• A. Reproduction over parental care
• B. Long lifespan with few offspring
• C. High investment in young survival
• D. Slow population growth rate

Answer: (A)

R-selected species are primarily characterized by their reproductive strategies that prioritize producing a large number of offspring over investing time and resources in parental care. This strategy is advantageous in unstable or unpredictable environments where the chances of survival for any given offspring may be low. By producing many offspring, R-selected species increase the likelihood that some will survive to adulthood, thus ensuring the continuation of their genes. This reproductive strategy contrasts with K-selected species, which tend to have fewer offspring but invest more energy into the survival and development of each individual. K-selected species often have longer life spans and may exhibit traits such as slow population growth and high investment in parental care. However, R-selected species thrive in conditions where population density can fluctuate, and their rapid reproduction can help them quickly exploit available resources.
