Answer 1

Autotrophic nutrition: 1 Mark each

1. Autotrophic nutrition is when an organism makes its own food instead of relying on other organisms.
2. Green plants are autotrophic by nature. They use sunlight, carbon dioxide, water, and mineral salts to perform photosynthesis.
3. Chlorophyll, the pigment in the plants that is responsible for the green color, helps the plant absorb the sunlight.
