    Study Notes

    Digestion and Nutrition

    • Breakdown of complex food compounds into simpler units is known as digestion.

    Role of Nutrients in Animals

    • Nutrients provide energy, building blocks, and essential molecules for proper body function.

    Energy Source for Plants

    • The main source of energy for plants is light energy from the sun.

    Acquisition and Ingestion of Food

    • The term used to describe the acquisition and ingestion of food by animals is feeding.

    Essential Requirements for Animals

    • Animals require essential nutrients, amino acids, and vitamins that they cannot synthesize for proper body function.

    Plant Synthesis

    • Plants use light energy, water, and carbon dioxide to synthesize all the components that constitute them.

    Exploitation of Food Resources

    • The success of how animals exploit food resources is compared with their ecological efficiency.

    Purpose of Nutrients in Animals

    • The main purpose of nutrients in animals is to provide fuel in terms of energy and raw materials for building and maintaining cellular machinery.

    Feeding and Nutrition

    • The acquisition and ingestion of food by animals, also known as feeding, is required to provide fuel in terms of energy and raw materials for building and maintaining cellular machinery.
