Plants that can prepare and store their own food using simple inorganic substances such as carbon dioxide, water, and minerals exhibit autotrophic nutrition.
Step 1: Autotrophs synthesize their own food by the process of photosynthesis using sunlight, carbon dioxide, and water.
Step 2: During photosynthesis, plants convert inorganic raw materials into organic food (like glucose), which can then be stored for later use.
Step 3: Heterotrophs depend on other organisms for food and hence cannot prepare food from inorganic substances.
Therefore, the given quality belongs to autotrophs.
