1. Be able to describe the characteristics of animal social behavior.

2. Be able to name several ways and meanings of information exchange in animal groups.

"Think about it, discuss it", think:

Why are the worker ants that make up the "raft" willing to "sacrifice" themselves? What do you think of this phenomenon?

Fire ants live in colonies. Although the worker ants making up the "raft" were "sacrificed", other members of the colony survived and continued the survival and reproduction of the species. Therefore, although this behavior is detrimental to the individual, it is beneficial to the group and even the species.

Social behavior: Animals that live in groups. Different members of the group divide labor and cooperate to maintain group life.

Think about answering the following questions:

1. What are the members of a termite colony? Is there a clear division of labor among various members? What are their responsibilities?

2. How do shepherds graze?

3. In a "hierarchical society" composed of a group of baboons, what privileges does the male baboon as the "leader" enjoy? What obligations do you have?

Privileges enjoyed by the baboon “leader”:

Priority in food and spouse;

Prioritize nesting sites;

Other members will make a submissive gesture towards it and dare not fight back against his attacks.

Obligations of the “leader”:

Responsible for directing the behavior of the entire community and working with other male baboons to defend the group.

Baboon group

The “leader” male baboon: enjoys both privileges and the obligation to defend the group.

"Hierarchical society": people are arranged in hierarchical order according to their size, strength, health and ferocity.

feature:

1. Form a certain organization;

2. There is a clear division of labor among members;

3. Form a hierarchy.

Characteristics of social behavior:

1. A certain organization is often formed within a group

2. There is a clear division of labor among members

3. Some groups also form hierarchies

Groups of animals that exhibit social behavior do not necessarily have a leader. For example: There is no "leader" in groups of lower animals such as termites. The queen ant is only responsible for laying eggs. This is her function and does not care about other things. Therefore, the queen ant does not have the function of "leader".

Animals that live in groups do not necessarily have social behaviors. For example, although sparrows live in groups, there is no clear division of labor among individuals, so they do not belong to social behavior.

Animals with social behavior not only live in groups, but more importantly, they have a clear division of labor, and a certain organization is often formed within the group.

In addition, groups of higher-level animals with social behavior will form a hierarchy, that is, a "leader."

What significance does animal social behavior have to animals?

It is often easier to obtain food and defeat the invasion of natural enemies by relying on collective strength, effectively ensuring the reproduction of species.

Survive, reproduce
