Sources of Food
Plants & animals are the major sources of food material.

Animal products: Ghee, milk, butter, egg, chicken, mutton etc.
Sources of Food from Animals
- Some of the foods we eat come from animals are milk, egg, chicken, meat, fish and honey. Milk is also converted into other useful products such as curd, butter, ghee and paneer. Milk is obtained from animals like cow, goat, buffalo, Camel etc.
- Cod liver oil, which we get from fish, is rich in vitamin A.
- Honey production: Honey is a food material which is produced by insects called bees. Bees collect nectar from the flowers of plants and convert it into honey.
- Chicken: We get from the hen.
- Mutton: We get from goat
Sources of Food from Plants
Plants are the major sources of food for human beings and other animals. Plants are the sources of food materials like cereals (wheat, maize, rice, sorghum, millet etc.), pulses, oils, fruits, vegetables, sugar, spices, tea and coffee etc.
Plants parts as food: The various parts of plants are used as a food material.
(1) Roots as food: Some plants store food in their roots. Example: Carrot, radish, beet, sweet potato and turnip.

Notes
The difference between a Fruit and Vegetable A fruit is what a flower becomes after it is pollinated. The seeds for the plant are inside the fruit. Vegetables are other parts of the plant, e.g. carrots are roots; lettuce is leaf etc.
Food Producers and Consumers
- Food Producers: Plants are called producers because they can make their own food.
The green plants make their own food by the process of photosynthesis with the help of water from the soil, carbon dioxide gas from the air, and energy from sunlight.
- Food Consumers: Animals are called consumers because they cannot make their own food, so they consume (eat) plants or animals as their food. The animals eat or consume plants and plant products, or other animals to get the food. Example: Animals and Human
Classification of animals on the basis of their food habit:
Herbivores: Animals that eat only plants.
Examples: Goat, cow etc.
Carnivores: Animals that eat only animals.
Examples: Lion, tiger etc.
Omnivores: Animals that eat both animals and plants. Humans are also omnivores.
Examples: Dog, cat etc.
