Question

drag each tile to the correct location.

match each trait that an organism displays to a reproductive strategy.

r-selected

• the average clutch size of the american green tree frog is 400 eggs.
• rhinoceroses weigh from 800 kilograms to more than 2,000 kilograms and have few offspring.

k-selected

• orangutan mothers care for their young for 7 to 8 years.
• great white sharks have a gestation period of 10 to 12 months.
• the oriental fruit fly reaches sexual maturity in 25 to 35 days and has a high rate of predation.

Explanation:

Understand r-selected and K-selected strategies

Organisms use different evolutionary strategies to reproduce.

• r-selected species focus on producing many offspring quickly. They typically have high reproductive rates, small body sizes, early maturity, short lifespans, and provide little to no parental care.
• K-selected species focus on long-term survival in stable environments. They typically have fewer offspring, larger body sizes, late maturity, long lifespans, long gestation periods, and invest heavily in parental care.

Analyze each trait tile

1. "The average clutch size of the American green tree frog is 400 eggs."

• Producing a large number of offspring (400 eggs) with minimal individual investment is a classic characteristic of an r-selected strategy.
• Classification: r-selected

1. "Rhinoceroses weigh from 800 kilograms to more than 2,000 kilograms and have few offspring."

• Large body size and producing very few offspring indicate high investment per individual, typical of K-selection.
• Classification: K-selected

1. "Orangutan mothers care for their young for 7 to 8 years."

• Long-term parental care and high investment in a single offspring are key traits of K-selection.
• Classification: K-selected

1. "Great white sharks have a gestation period of 10 to 12 months."

• A long gestation period and slow development are characteristic of K-selected species.
• Classification: K-selected

1. "The oriental fruit fly reaches sexual maturity in 25 to 35 days and has a high rate of predation."

• Rapid development to maturity and high mortality/predation rates are classic traits of r-selected species.
• Classification: r-selected

Group the tiles into correct categories

• r-selected:
• The average clutch size of the American green tree frog is 400 eggs.
• The oriental fruit fly reaches sexual maturity in 25 to 35 days and has a high rate of predation.

• K-selected:
• Orangutan mothers care for their young for 7 to 8 years.
• Great white sharks have a gestation period of 10 to 12 months.
• Rhinoceroses weigh from 800 kilograms to more than 2,000 kilograms and have few offspring.

Answer:

The correct matching of traits to each reproductive strategy is:

r-selected

• The average clutch size of the American green tree frog is 400 eggs.
• The oriental fruit fly reaches sexual maturity in 25 to 35 days and has a high rate of predation.

K-selected

• Orangutan mothers care for their young for 7 to 8 years.
• Great white sharks have a gestation period of 10 to 12 months.
• Rhinoceroses weigh from 800 kilograms to more than 2,000 kilograms and have few offspring.
