R-strategist species have many offspring with little parental care, while K-strategist species have fewer offspring with more parental care.
Male C. elegans have specialized reproductive organs and produce sperm, while hermaphrodite C. elegans have both male and female reproductive organs and can self-fertilize. This difference in reproductive strategies allows for increased genetic diversity in populations with both males and hermaphrodites.
In many species, the heterogametic sex (typically males) produces different types of sex cells (sperm) while the homogametic sex (typically females) produces only one type of sex cell (egg). This difference in sex cell production leads to different reproductive strategies, with males typically producing many small, mobile sperm to increase the chances of fertilization, while females produce fewer, larger, and less mobile eggs. This difference in reproductive strategies is known as anisogamy.
K-selected and r-selected reproductive strategies differ in their impact on population growth and survival. K-selected species have fewer offspring but invest more resources in each individual, leading to slower population growth but higher survival rates. In contrast, r-selected species produce many offspring with minimal parental care, resulting in rapid population growth but lower individual survival rates.
Amphibians typically lay eggs in water and undergo external fertilization, while mammals give birth to live young and undergo internal fertilization. Mammals also provide parental care to their offspring, while most amphibians do not.
Species that exhibit multiple sexes, such as some plants and animals, have different reproductive strategies compared to species with only two sexes. These species may have more complex mating systems, with individuals having specific roles in reproduction. They may also have different ways of producing and fertilizing gametes, leading to a wider variety of genetic combinations in offspring. Overall, the presence of multiple sexes can result in greater genetic diversity and potentially more complex social behaviors related to mating and reproduction.

Sexual dimorphism has arisen as a result of different selective pressures acting on males and females of a species due to differences in reproductive roles and behaviors. It is often driven by competition for mates, mate choice, or differences in parental investment strategies. Evolution favors traits that enhance reproductive success in each sex, leading to distinct physical or behavioral differences between males and females.
In many species, the heterogametic sex (typically males) produces different types of sex cells (sperm) while the homogametic sex (typically females) produces only one type of sex cell (egg).

Human spermatozoa are longer and have a different shape compared to rat spermatozoa. Additionally, human spermatozoa have a higher motility rate and larger head size in comparison to rat spermatozoa. These differences contribute to the variations in reproductive strategies between humans and rats.
yes there is difference
Flowers are one of the reproductive strategies used by (some) plants. So the answer is yes.
K-selected and r-selected reproductive strategies differ in their impact on population growth and survival. K-selected species have fewer offspring but invest more resources in each individual, leading to slower population growth but higher survival rates. In contrast, r-selected species produce many offspring with minimal parental care, resulting in rapid population growth but lower individual survival rates.

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.
