Question 2. How are cactus adopted to survive in a desert??
Answer: Adaptation of cactus in desert:
(i) The Leaf is modified to spine to reduce transpiration.
(ii) Photosynthesis is carried by the stems.
(iii) The stem is covered by thick waxy layer that helps to retain water.
(iv) Cactus have roots that go very deep into the soil for absorbing water.

Question 8. Explain, why speed is important for survival in the grasslands for animals that live there. (Hint: There are few trees or places for animals to hide in grasslands habitats)
Answer: In grasslands, mainly grasses are found. Trees are very few in number. Predators such as lion, tiger, etc. that feed upon other animals are commonly found in these regions. It is very easy for these predators to locate their prey in the grass. Therefore, to protect themselves from these predators, animals adapt themselves by increasing their speed. The increased speed of the animal helps the weaker animals to escape their predator, thereby protecting themselves and increasing the chances of their survival.
