Match each trait that an organism displays to a reproductive strategy. r-selected or k-selected.
1. the average clutch size of the american green tree frog is 400 eggs.
2. orangutan mothers care for their young for 7 to 8 years.
3. rhinoceroses weigh from 800 kilograms to more than 2,000 kilograms and have few offspring.
4. the oriental fruit fly reaches sexual maturity in 25 to 35 days and has a high rate of predation.
5. great white sharks have a gestation period of 10 to 12 months.

1: R selection

2: K selection

3: K selection

4: R selection

5: K selection.

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.

that is wrong, its not thymus.
