Patterns of Behavior

2. Animals use: sounds, scents, body movements
Communication
Animals use: sounds, scents, body movements
Pheromone – chemical released by one animal that affects the behavior of another animal

3. Competitive Behavior
Animals compete with one another for limited resources, such as food, water, space, shelter, and mates

4. Showing Aggression
Aggression is a threatening behavior that 1 animal uses to gain control over another.
Aggression between members of the same species hardly ever results in the injury or death of any competitors

5. Establishing A Territory
Territory – area that is occupied and defended by an animal or group of animals
By establishing a territory, an animal protects its access to resources such as food, mates, and a safe area

6. Attracting A Mate
Courtship Behavior – behavior in which males and females of the same species prepare for mating.
Ensures that the males and females recognize one another, so that the mating process can occur.

7. Living in groups enables animals to cooperate and survive
Group Behavior

8. Living in groups protects animals against predators
Safety In Groups
Living in groups protects animals against predators
Animals in a group sometimes cooperate in fighting off a predator

9. Animal Societies
Societies – is a group of closely related animals of the same species that work together in a highly organized way
There is a division of labor – different individuals perform different tasks
Examples: ants, termites, honeybees, pistol shrimp

11. Cyclic behaviors usually change the course of a day or a season.
Behavior Cycles
Cyclic behaviors usually change the course of a day or a season.
These occur in regular, predictable patterns

12. Circadian Rhythms – behavior cycles that occur over a day
Daily Cycles
Circadian Rhythms – behavior cycles that occur over a day
Example: Blowflies search for food during the day and rest at night

13. Hibernation Some behavior cycles are related to seasons
Hibernation is a state of greatly reduced body activity that occurs during the winter when food is scarce.
During hibernation: breathing and heartbeat slows down
Bodies use stored fat to meet their needs

14. Migration
Migration is the regular, seasonal journey of an animal from 1 place to another and back again.
Animals usually migrate to an area that provides a lot of food or a good environment for reproduction.
Animals use sight, taste, and other senses including some that humans do not have
