Answer:
1st. R-selected, 2nd. K-selected, 3rd. K-selected, 4th. R-selected, 5th. K-selected.
Step-by-step explanation:
The K-selected species shows a large size of the body, gradual development, and lengthier life span. They generate very little offspring during their whole life and offer post-natal care. On the other hand, the R-selected species exhibit small size of the body and show brisk development. They exhibit brief life span and generate huge number of offspring.
Thus, of the mentioned options, the generation of the huge number of eggs by American green tree frog, the rapid reproduction and brief life span in fruit fly makes them R-selected species. While the lengthier gestation period, post-natal care, and the generation of new offspring make the remaining the K-selected species.
