Circle the correct answers.
1. (Amoeba / Whale / Dolphin) breathes through its body surface.
2. A baby frog or a tadpole breathes through (air tubes / body surfaces / gills).
3. (Birds / Crabs / Prawns) breathe through lungs.
Answer (2)
The correct answers are Amoeba for the first question, gills for the second, and Birds for the third. An amoeba breathes through its body surface, a tadpole breathes through gills, and birds breathe through lungs. These respiratory methods are essential for the survival and efficiency of each organism in its environment.

The correct answer is Amoeba . Amoebas are simple, single-celled organisms that don't have specialized structures like the lungs or gills. Instead, they take in oxygen directly through their cell membrane by a process known as diffusion. This is possible because amoebas typically live in water or moist environments where oxygen is dissolved.
A baby frog or a tadpole breathes through gills . Tadpoles, which are the larval stage of frogs, live in water and have gills similar to fish that allow them to extract oxygen from the water. As they develop into adult frogs, they undergo metamorphosis, and their gills are replaced with lungs that enable them to breathe air.
The correct answer is Birds . Birds breathe through lungs. They have a unique respiratory system that includes air sacs, which allow for a continuous flow of air through the lungs, providing them with a very efficient means of oxygen exchange. This system helps them maintain high energy levels needed for flight.
