Key Insights

  • 🛩ī¸ Carbon dioxide is present in the air, but in a very small percentage (0.03%).
  • ❓ Burning and respiration are processes that produce carbon dioxide.
  • 😋 Plants need carbon dioxide for photosynthesis, which is essential for their survival and the production of food.
  • đŸĢĸ The exchange of oxygen and carbon dioxide between plants and animals is crucial for the balance of gases in the environment.
  • 🌱 Plants and animals are interdependent, with plants providing oxygen for animals through photosynthesis, and animals providing carbon dioxide for plants through respiration.
  • 😋 The survival of plants is essential for the survival of other organisms, as they are at the base of the food chain.
  • đŸĢĸ Oxygen and carbon dioxide play vital roles in maintaining the balance of gases in the environment.

Transcript

hello friends this video on air around the Spartan is brought to you by exam fee or comms normal fear from exam so that was all about oxygen the the next gas that we will talk about is carbon dioxide so this is another important gas however it is present in very minut amount in the air so it is present in very small amounts 0.03 percent of the air ...

Questions & Answers

Q: How is carbon dioxide produced in the atmosphere?

Carbon dioxide is produced through burning and respiration. When substances burn, they need oxygen, and as a result of the burning process, carbon dioxide is produced. Similarly, respiration in animals and humans also releases carbon dioxide.

Q: Why do plants need carbon dioxide?

Plants need carbon dioxide for photosynthesis, which is the process by which they produce their own food. Without carbon dioxide, plants cannot undergo photosynthesis and will not be able to survive.

Q: How are oxygen and carbon dioxide exchanged between plants and animals?

During photosynthesis, plants take in carbon dioxide from the atmosphere and release oxygen. Animals, on the other hand, undergo respiration, in which they take in oxygen and release carbon dioxide. This exchange of gases ensures that both plants and animals have the necessary gases for their survival.

Q: What happens if plants do not survive?

If plants do not survive, animals, including humans, would not have a source of food. Plants are at the base of the food chain, and many animals are dependent on them either directly or indirectly. Thus, the survival of plant species is crucial for the survival of other organisms.

Summary & Key Takeaways

  • Oxygen and carbon dioxide are both present in the air, with carbon dioxide at a very small percentage (0.03%).

  • Carbon dioxide is produced through processes such as burning and respiration, and is also released by animals and plants.

  • Plants need carbon dioxide for photosynthesis, a process in which they prepare their own food, while animals rely on plants directly or indirectly for their food.
