Question 3.
Describe all types of behaviour discussed in the lesson with appropriate examples. (AS 1)
(OR)
Describe different types of animal behaviours discussed in the classroom with suitable examples.
Answer:
Scientists categorize animal behaviour into different categories like instinct, imprinting, conditioning, imitation.
1) Instinct:
A) Instinctual behaviours are behaviours that need not be learned.
B) They are inborn behaviours and can be complex like making nest by birds, choose mates and forming into groups for protection.
C) Reflexes are also a type of instinct behaviour.
2. Imprinting:
A) Chickens and ducklings are able to walk almost immediately after hatching from the egg.
B) Duckling can even swim after a few days.
C) They recognise their mother because of a behaviour type called imprinting.
D) Imprinting lets young animals recognise their mother from a young age. They can follow her for food and protection.
3. Conditioning:
A) Conditioning is a type of behaviour involving a response to a stimulus that is different from the natural one.
B) It is a type of learned behaviour.
C) If we take ringing of school bell as an example, student shows different types of conditioning to a school bell as per the time.

Question 4.
Differentiate between (AS 1)
Answer:
a) Imitation and Imprinting.
Question 5.
How human behaviour is different from behaviour of other animals? Explain with an example. (AS 1)
Answer:
- Humans show many of the same types of behaviour as other animals.
- But human behaviour is often more complex because we are more intelligent and aware of ourselves.
- For example, hungry persons might want to start eating immediately when they sit down at the dining table.
- But the humans have learned that good manners mean they should wait until everyone is seated and ready to eat.
- But animals eat food whenever they find it.
Question 6.
Observe ants going on a line. Ask your teacher how they communicate and write a note on this. (AS 4)
Answer:
- Ants talk to each other using chemical signals called pheromones that they detect with antennae.
- Ants use their antennas to pick up smells.
- For example, when ants find food they have a pheromone trail from the food soure to the colony.
- Other ants follow this trial. As the other ants follow the trial, the pheromone scent becomes stronger.
- The paired antennas of ants provide information about the direction and intensity of scents.
- Since most ants live on the ground, they use the soil surface to leave pheromene trail that may be followed by other ants.
- Some ants produce sounds using gaster segments and their mandibles.
- Sounds may be used to communicate with colony members or with other species.
Question 7.
“Understanding of animal behaviour creates positive attitude towards animals”. How do you support this statement? Explain with suitable examples. (AS 6)
Answer:
- I support the above statement that understanding of animal behaviour creates positive attitude towards animals.
- Animals usually make sounds depending upon their needs. They show different facial expressions.
- For example, cattle make sounds whenever they need food and water.
- After giving food and water by the master they calmdown.
- When a crow dies, all the other crows come around making sounds ‘kaww, kaww’ shows their sadness, we have to understand nature of the crows in this situation.
- We have to identify the unity and integrity among the ants when they go in line in search of food.
- When dogs bark during nights, we should understand that they are doing that for our safe.
- We have to show positive attitude towards animals who are useful in our daily life. Live and let live should be our motto.
Question 8.
Look at this picture. How do you feel about sibbiling care nature of animals. Have you ever seen such kind of situations in your surroundings? Explain in your own words. (AS 7)
Answer:
- Sibbiling care nature of animals are animals with instinct behaviour.
- Every animal take care of their young ones until they are grown adults.
- I observed sibbiling care situations in my surroundings.
- The newly hatched chickens are taken by their mother to surrounding places to feed them.
- Whenever the chicks faces danger mother brings them under her wings.
- When the eagle tries to take away the chicks the mother attacks the eagle to save its chickens.
- Chicken feeds and protect young ones until they are able to collect their own food.
- A new born kitten is born blind. Its eyes normally do not open until it is 10 to 12 days.
- Finding the milk source is accomplished with help from mom, who encourages young kittens to feed a few minutes after birth.
- Cat often changes its living place by transfering young kitten. It does so to protect kittens from enemies.
9th Class Biology 7th Lesson Animal Behaviour Activities
Lab Activity
Question 1.
Behaviour of Cockroach : For this we need a choice box and calcium chloride.
Answer:
Making of Choice box :
- Take a box, and divide it into four chambers with the help of a card board.
- Make tiny holes in any two chambers of one side so that light can pass through these holes into the chambers.
- Let other two chambers as it is (dark).
- Now create humid environment with help of moist cotton wool in one of the lightened and one of the dark chambers.
- Create dry atmosphere with help of calcium chloride in one of the lightened and one of the dark chambers.
- So, the box has been divided into four chambers with different conditions i.e., light and dry, light and humid, dark and dry, dark and humid.
- Make four groups in class. Each group will put several cockroaches into a choice of chamber with four different conditions.
- Cover the box and leave the setup for 15-20 minutes.
- Count the number of cockroaches in each chamber.
Observations :
- Cockroaches prefer dark and damp conditions.
- The quarter of the choice chamber with these conditions contains most or all of the cockroaches.
