A. Terrestrial monkeys are more lithe and agile than arboreal monkeys.
B. Sexual dimorphism tends to be more marked in terrestrial than in arboreal monkeys.
C. Terrestrial monkeys are larger than arboreal monkeys.
D. Terrestrial monkeys face fewer predators than arboreal monkeys.

Answer 1

Terrestrial Old World monkeys are larger, show more sexual dimorphism, and face fewer predators compared to arboreal monkeys.

Step-by-step explanation:

Traits of terrestrial, as opposed to arboreal, Old World monkeys include:

1. Terrestrial monkeys are larger than arboreal monkeys. Terrestrial monkeys are adapted to life on the ground and tend to be larger in size.
2. Sexual dimorphism tends to be more marked in terrestrial than in arboreal monkeys. Terrestrial monkeys often display greater differences in size between males and females compared to arboreal monkeys.
3. Terrestrial monkeys face fewer predators than arboreal monkeys. Being on the ground provides terrestrial monkeys with fewer predators than arboreal monkeys that live in trees.
