  1. To hibernate in the winter

  2. Changing colours to suit with its surroundings

  4. To migrate to long distances in the winter

Show answer
Correct Option: B

Their slow movement and blending into the surrounding environment make it hard for predators to spot them. Their colour changes also help them in mating as they shift colours while communicating with other chameleons. Their colour change also depicts their reactions such as they display darker colours when empty or when under stressed environmental conditions.  Thus, the correct answer is option B.

Which of the following title best suits the above animal?

adaptations - european woodland and african grassland adapting to a habit plant adaptations adaptations to different ecosystems biology

  1. Terrestrial animal

  2. Aquatic animal

  3. Amphibian

  4. Arboreal animal

Show answer
Correct Option: D
Explanation:

Arboreal animals are those which spend most of their time on trees. For example Koala, Lemur, Spider monkey , tree sloth. Such animals show variety of adaptations so that they can easily ascend and descend from the trees. 

1. Tree Sloth have huge claws to hang them from trees. 
2. They have stretchy membranes between their legs or toes for extensive gliding. 
3. They have elongated limbs to cross gaps and reach their food resources and also to provide support. 
4. They have prehensile tail to grasp the branches.
5. They are generally small sized to be able to move easily through cluttered habitat. 
The most common adaptations of terrestrial animals is the legs to walk on land and lungs for respirations. 
Aquatic animals are adapted for swimming for which they have streamlined body and gills for respiration. 
Amphibians are adapted to live both on land as well as water for which they have moist skin as well as lungs for respiration. 
Thus, the correct answer is option D.

adaptations - european woodland and african grassland adapting to a habit plant adaptations adaptations to different ecosystems biology

  1. Camel, walking

  2. Lizard, hibernation

  3. Monkey, grasping

  4. Kangaroo, hopping

  • Hence, the opposable thumb is found in monkey and it helps in grasping.
So, the correct answer is 'Monkey, grasping'.
