A) Digestion
B) Respiration
C) Excretion
D) None of these
🧠 Explanation:
Respiration is the opposite of photosynthesis. Plants use sunlight in photosynthesis to make food and oxygen. Respiration is when people and animals use oxygen to turn food into energy, releasing carbon dioxide. Think of plants as chefs making oxygen for us, and we use it like fuel for a car. For kids, it’s like breathing out after eating to stay active. This cycle keeps nature balanced. Understanding respiration shows children how living things work together, teaching them how our bodies use food and air to run, play, and grow strong every day.
