Final answer:
R-selected and K-selected species are two different types of species reproductive strategies. R-selected species produce many offspring with less energy invested, while K-selected species produce fewer offspring with more energy invested.
Step-by-step explanation:
The term that describes the two different types of reproductive strategies in species is species reproductive strategy. These two strategies are known as r-selection and K-selection.
R-selected species have reproductive strategies that involve producing many offspring at once. They have a high reproductive rate and invest less energy in each individual offspring.
K-selected species, on the other hand, have reproductive strategies that involve producing fewer offspring but investing more energy in each individual offspring. They have a lower reproductive rate but a higher survival rate for their offspring.
