Birds, Insects and Fish

Birds, Insects and Fish for Class 2 Science

Based on the body structures and different habitats of animals, living organisms can be grouped as birds, insects, mammals, reptiles, amphibians, fish, and many more.
This concept will give an idea to the learners about birds, insects, and fish.

After reading the concept, students will be able to:

• State the importance of colourful feathers of birds.
• Understand the different uses of beaks and claws in the birds.
• Describe the uses of fish fins.
• State the reason behind the streamlined body shape of the birds and fishes.
• Answer how many legs do insects have?
• Recognise some types of insects around them.
• Differentiate between land animals and aquatic animals.

Each concept is explained to class 2 students using descriptions, illustrations, and concept maps. After you go through a concept, assess your learning by solving the two printable worksheets given at the end of the page.

• Do you know that birds, insects, and fish are different types of animals?
• Birds can fly, fish can swim in the water, and insects have jointed limbs and can fly.
• These three types of animals have different feeding habits, share different habitats, and have different body parts with various functions.

Bird:

 

1) Wings:

 

2) Beak:

• The jaws of a bird are modified into a beak.
• Some birds have tiny beaks, and some have large pointed and hooked beaks.
• Beaks help in eating. Birds use their beaks to crack seeds and grains. Larger beaks are also used to tear food and catch small fish from the water.

Examples:

 

 

3) Claws:

• The legs of the birds are modified for perching, hopping, scratching, swimming, etc.
• At the end of their legs, they have narrow and curved nails called claws.

Examples:

 

Habitats of Birds:

• The habitats of birds can be of different types. Almost all birds make nests in different places.
• In urban areas, birds may live in empty buildings, on the rooftops, or tree branches. Birds make nests by using leaves, twigs, clay, etc.
• Some birds like to make nests on the ground. Birds like to make their nests near water and food sources.

Examples:

Insects:

• Beetles, cockroaches, bedbugs, crickets, etc., are called insects.
• The body of an insect can be divided into three parts- head, trunk, and abdomen.
• Insects have three pairs of legs that are jointed.
• There is a pair of antennae on the head that helps them to sense things.
• Insects have a pair of thin wings on their back.

 

Habitats of insects:

• Insects can live easily in any place on this earth.
• We can find insects in hot deserts, wet forests, and snowy regions.
• Some insects like water striders can also be found in the water.
• Insects like honeybees, ants, and wasps live in groups and are called social insects.

Examples:

 

Feeding Habits of Insects:

 

Fish:

• Fish live in the water. Some types of fish live in the river, and some live in the ocean.
• Fishes cannot survive without water; hence their bodies are adapted to aquatic habitats as follows:

 

1)Streamlined Body Shape::

 

2)Gills for Breathing:

• Fish can breathe underwater; they have gills through which they can exchange respiratory gases in the water.

 

3)Fish Fins:

• Fish can swim in the water and move from one place to another
• Fishes use their fins and tails to swim and change directions.

 

Feeding Habits of Fish:

• Fish eat aquatic plants, algae, insects, and worms.
• Larger fish prey on smaller fish, frogs, and turtles.

 

New Words:

 

Did You Know?

• The nest of a weaver bird is called a pendant.
• An insect’s eye is a bunch of many tiny eyes that can see an object separately and are called compound eyes.
