Answer:
1: R selection
2: K selection
3: K selection
4: R selection
5: K selection.
Step-by-step explanation:
K-selection species exhibit large body size, slow development, and long life span. They produce few offspring during life time and provide post natal care. The R- selection species have small body size and exhibit rapid development. They have short life span and produce large number of progeny.
Among the given options, production of large number of eggs by American green tree frog, short life span and rapid reproduction in fruit fly makes then R-selection species. Long gestation period, post natal care and production of few offspring make the rest as K selection species.
