Test on Social Organization in Animals

Question 1: African wild dogs primarily immobilize their prey by having multiple pack members simultaneously bite and hold different limbs.

A. Ano

B. Ne

Explanation: According to the study materials, wild dogs immobilize their prey by having one dog grab its tail and another its upper lip, not by multiple pack members biting different limbs simultaneously.

Question 2: Social organization in animal groups improves an individual's survival and reproductive success.

A. Ano

B. Ne

Explanation: The study materials state that social organization 'improves the survival and reproductive success of an individual'.

Question 3: Which term describes the phenomenon where a herd scatters in all directions when a predator attempts to single out prey, thereby confusing the predator?

A. The dilution effect

B. The confusion and distraction effect

C. Collective mobbing

D. Cooperative hunting

Explanation: The study materials state that when a predator tries to single out its prey, the herd scatters in all directions, confusing the predator. This is known as the confusion and distraction effect.

Question 4: Which statement accurately defines the dilution effect as a strategy for group survival?

A. It is the phenomenon where a large herd scatters in all directions to confuse a predator.

B. It describes the increased survival chances of an individual when the number of individuals in its group is greater.

C. It refers to the collective action of a large group surrounding and overpowering a predator.

D. It explains how a group provides guidance and protection to inexperienced members during migration.

Explanation: The study materials define the dilution effect as: 'The greater the number of individuals in a group, the greater the survival chances are of the individual.' This directly matches option 1. The other options describe other predator avoidance strategies mentioned in the materials, such as the confusion and distraction effect (option 0) or mobbing (option 2), or general protection (option 3).

Question 5: Termite workers, unlike workers in ant, bee, and wasp colonies, can be either male or female.

A. Ano

B. Ne

Explanation: The study materials explicitly state: "Unlike ants, bees and wasps, termite workers may be male or female." This confirms that termite workers can indeed be both male and female, distinguishing them from the worker castes of ants, bees, and wasps as described.
