| Example | Cow, Goat, Deer, Elephant | Bear, Crow, Dog, Human |
Question 2: How does a lizard take its food?
Answer: A lizard sits quietly near insects. When a fly or moth comes close, it shoots out its long, flexible, sticky tongue. The insect sticks to the tongue, and the lizard pulls it back into its mouth and swallows it whole without chewing.
Question 3: Explain the term “chewing the cud”.
Answer: Some plant-eating animals like cows, buffaloes, and camels quickly swallow their food without chewing when grazing. Later, when they rest, they bring small portions of the half-digested food back from the stomach into the mouth and chew it thoroughly with their back flat teeth. This process is called chewing the cud (or rumination).
Question 4: Write any two ways that can help us in taking care of domestic animals.
Answer:
- 1. Clean Shelter & Hygienic Water: Provide clean, airy, and dry sheds that are regularly washed and disinfected, along with fresh drinking water.
- 2. Nutritious Food & Veterinary Care: Feed them wholesome, appropriate fodder and take them to a veterinary doctor whenever they fall ill.
Question 5: How do butterfly and mosquito have their food?
Answer: Both butterflies and mosquitoes have a long, sharp, hollow needle-like feeding tube attached to their mouthparts. A butterfly inserts this tube deep into flower blossoms to suck sweet nectar, while a mosquito uses it to pierce animal skin and suck blood.
