Answer 1

Nutrition:

1. Nutrition is defined as a biochemical and physiological process that helps an organism to use food and sustain life.
2. Nutrition involves food intake and converting it into energy.
3. Nutrients are essential for living organisms to maintain proper growth and development. For example, carbohydrates and proteins.

Modes of nutrition:

Autotrophic mode:

1. The types of organisms that perform photosynthesis to synthesize food are called autotrophs.
2. Autotrophic organisms utilize sunlight and inorganic carbon to form organic compounds. For example, green plants.

Heterotrophic mode:

1. The types of organisms that cannot synthesize their food and rely on other organisms like autotrophs for nutrition are called heterotrophs.
2. The heterotrophs cannot form organic compounds and obtain them from other sources like plants or animals. For example, animals.
