FAQs on Breathing in Earthworm Video Lecture - Science Class 7
| 1. How do earthworms breathe? |  |
Ans. Earthworms breathe through their skin, a process known as cutaneous respiration. They have a moist and thin skin that allows oxygen to pass through and carbon dioxide to be released. This is why earthworms are commonly found in damp soil or moist environments.
| 2. Do earthworms have lungs? | |
Ans. No, earthworms do not have lungs. They do not possess any specialized respiratory organs like lungs or gills. Instead, they rely on their skin to exchange gases with the surrounding environment. This is why it is important for them to live in moist habitats.
| 3. Can earthworms survive without oxygen? | |
Ans. Earthworms require oxygen for survival, just like any other living organism. They breathe in oxygen through their skin and release carbon dioxide. Without sufficient oxygen, they would not be able to carry out essential bodily functions and would eventually die.
| 4. How do earthworms adapt to their environment for breathing? | |
Ans. Earthworms have evolved certain adaptations to ensure efficient breathing. Their skin is thin and contains numerous blood vessels, allowing for easy exchange of gases. They also secrete mucus to keep their skin moist, which is vital for the absorption of oxygen. Additionally, they prefer to live in moist soil or environments to maintain the necessary conditions for respiration.
| 5. What happens if an earthworm's skin dries out? | |
Ans. If an earthworm's skin dries out, it would not be able to respire properly. The exchange of gases through the skin requires moisture, and a dry skin would hinder this process. The earthworm may suffocate and die if it remains in a dry environment for an extended period. Therefore, it is crucial for earthworms to stay in moist habitats to ensure their survival.
