Q4: True or False.


(i) All animals need air, water, and food to survive.
Ans: True
These are the basic necessities for any living organism to survive and carry out their life functions.

(ii) Fishes have lungs to breathe underwater.
Ans: False
Gills allow fish to extract oxygen from water as it passes over them, allowing them to breathe underwater.

(iii) Herbivores eat plants for their nutrition.
Ans: True
Herbivores are animals that primarily eat plants for their nutrition, such as cows, elephants, and rabbits.

(iv) The skeleton inside the body is called an exoskeleton.
Ans: False
An endoskeleton is an internal skeleton that provides structural support and protection for internal organs, while an exoskeleton is a hard outer covering found in some invertebrates, like insects and crustaceans.

(v) The process of breaking down food into simpler substances is called digestion.
Ans: True
Digestion is the process by which food is broken down into simpler, absorbable nutrients that can be used by the body for energy and growth.

Q5: Give reasons.


(a) Birds like Ostrich, emu, and penguin cannot fly.
Ans: Because they have evolved to have large, heavy bodies and small wings, which makes it difficult for them to generate enough lift to become airborne. These birds have adapted to their environments in other ways, such as running (Ostrich and emu) or swimming (penguin) instead of flying.

(b) Ducks, Fowls, and bears are called omnivores.
Ans: Because they have a varied diet that includes both plant matter (such as fruits, vegetables, and grains) and animal matter (such as insects, fish, and small mammals). Their ability to consume a wide range of foods allows them to adapt to different environments and survive on diverse food sources.

(c) Animals like cow, sheep, goat, zebra, and horse have sharp front teeth (incisors) and large flat back teeth (molars).
Ans: Because they are herbivores. The sharp front teeth help them to bite and cut plant material, while the large flat back teeth are used for grinding and chewing the fibrous plant matter they consume.

Q6: Short Answer Questions.


(i) What is the primary difference between mammals and birds?
Ans: The primary difference between mammals and birds is that mammals have hair or fur, give birth to live young, and produce milk to feed their young. Birds have feathers, lay hard-shelled eggs, and do not produce milk.

(ii) How do fish breathe underwater?
Ans: Fish breathe underwater by extracting oxygen from the water through their gills. As water passes over the gills, oxygen is absorbed into the bloodstream, and carbon dioxide is released.

(iii) Why do some animals have camouflage?
Ans: Some animals have camouflage to help them blend in with their surroundings. This helps them avoid predators or hide from their prey.

(iv) Name two animals that are carnivores and two animals that are herbivores.
Ans: 

  • Carnivores: Lion, Tiger
  • Herbivores: Elephant, Cow

(v) Describe the life cycle of a butterfly.
Ans: The life cycle of a butterfly consists of four stages: egg, larva (caterpillar), pupa (chrysalis), and adult. The adult butterfly lays eggs on a host plant, which hatch into caterpillars. The caterpillar eats and grows until it forms a chrysalis. Inside the chrysalis, the caterpillar undergoes metamorphosis and emerges as an adult butterfly.

(vi) Name the body covering of the following animals.
Ans:

  • Snail - Soft and slimy body covering, often referred to as a "shell."
  • Fish - Scales covering the body.
  • Sheep - Wool (fleece) covering the body.
  • Polar bear - Fur (thick coat) covering the body.

(vii) How do the following animals move?
Ans:

  • Turtles: Turtles move by using their legs to walk on land. In water, they swim by moving their legs in a paddling motion.
  • Penguins: Penguins are excellent swimmers. They use their wings as flippers to propel themselves through the water, and their feet are used for steering.
  • Water boatman: Water boatmen move by rowing their legs like oars. They have long, flattened legs adapted for this purpose and are skilled at moving on the water's surface.

FAQs on Animal Life - 1 Class 6 Worksheet Science

1. What are some characteristics of animal life?
Ans. Animals are characterized by the ability to move, consume organic material for energy, and reproduce sexually. They also have specialized sensory organs and nervous systems that allow them to respond to their environment.
2. How do animals obtain energy?
Ans. Animals obtain energy by consuming organic material, such as plants or other animals. They break down this material through a process called digestion and extract the energy stored in it for their own use.
3. What is the importance of reproduction in animal life?
Ans. Reproduction is crucial for the continuation of animal life. It ensures the survival of the species by producing offspring that can carry on the genetic traits and adapt to changing environments. It also allows for genetic diversity, which is important for the overall health and resilience of the population.
4. How do animals adapt to their environment?
Ans. Animals adapt to their environment through a process called natural selection. Individuals with traits that are advantageous for their specific environment are more likely to survive and reproduce, passing on those traits to future generations. Over time, this leads to the development of adaptations that help animals better survive and thrive in their particular habitat.
5. What are some examples of specialized sensory organs in animals?
Ans. Animals have a variety of specialized sensory organs that allow them to perceive their surroundings. Examples include eyes for vision, ears for hearing, noses for smelling, tongues for tasting, and skin for touch. These sensory organs help animals gather information about their environment, locate food, detect predators, and communicate with other members of their species.
