Review Questions Chapter 13 Biology 
Section 1
1. Define mutualism and commensalism.
Mutualism- Both are benefited
Commensalism- One benefits the other doesn't care.
2. Give examples of mutualism.
Oxpeckers (a type of bird) and Zebras, the Oxpecker picks ticks and parasites off of the Zebra. The oxpecker gets food and the Zebra gets pest control.
3. Explain why most parasites do not kill their host. Why is it in their own best interest to keep their host alive?
If a parasite kills its host the parasite will most likely die too
Section 2
1. Define animal behavior.
Animal behavior is how animals interact with each other and their environment
2. What is the nature-nurture debate?
Nature behavior determined by genetics
Nurture behavior determined by past experiences
3. What is kin selection?
Kin selection is natural section affected by genes passed on to offspring
4. How do behaviors become common?
Behaviors become common when they are repeated and passed on
Section 3
1. What is learning?
Experiences that change or alter behavior over time are learned
2. Name three types of learning in animals.
Rats, Monkeys, Kittens
3. Compare and contrast instinct and learning.
Instint
● Genetics
● Can’t control it
● Can’t change it
Learned
● Must be taught
● Can be controlled
● Can change
Section 4
1. What are innate behaviors? Give an example.
Innate behaviors are determined by your genes.
→ Cat using litter box, babies nursing
2. What would happen to an individual who poorly performs innate behaviors?
May not survive
3. What is an instinct?
An instinct is the ability of an animal to perform a behavior the first time it is exposed to the proper stimulus.
Section 5
1. Explain why communication is necessary for social living.
Communication is needed for understanding and working together for survival
(sound, scents, makings, body language)
2. Describe communication in ants.
3. What is aggression?
Showing others to fall back or stop in order to protect what’s yours
4. What type of competition occurs between two
1. Define mutualism and commensalism.
Mutualism- Both are benefited
Commensalism- One benefits the other doesn't care.
