ANIMAL BEHAVIOR

INTRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Zebras live in large herds. When attacked by a predator, such as a lion, some individual zebras will engage in combat with the lion, rather than trying to escape. This behavior increases the risk of injury and death to the individual zebra. Why might this type of behavior evolve if it is so clearly a disadvantage to the individual?
A
This behavior increases the survival advantage of other members of the herd and the species.
B
This behavior ensures that only the strongest and most aggressive zebras pass on their genes.
C
This behavior is an opportunity for zebras to prove themselves to potential mates.
D
This behavior frightens predators in the area and makes future attacks less likely.
Explanation: 

Detailed explanation-1: -Living in groups provides animals with many benefits. A large group of animals is less likely to be bothered by predators, there are more females to care for and protect the young, and more members to look for food sources. Working together provides them with more opportunities for survival than living alone does.

Detailed explanation-2: -Mechanical defenses, such as the presence of thorns on plants or the hard shell on turtles, discourage animal predation and herbivory by causing physical pain to the predator or by physically preventing the predator from being able to eat the prey.

Detailed explanation-3: -Camouflage, highly developed senses, warning signals, and different defensive weapons and behaviours are all used by prey animals for survival. Camouflage is an adaptation in which a species evolves to resemble its background.

Detailed explanation-4: -Organisms use camouflage to mask their location, identity, and movement. This allows prey to avoid predators, and for predators to sneak up on prey. A species’ camouflage depends on several factors. The physical characteristics of the organism are important.
