What are The Five Primary Sources of Food?
Food is essential for survival, providing the body with the necessary nutrients to function properly. But have you ever wondered where food comes from? Understanding food sources is crucial for maintaining a balanced diet and leading a healthy lifestyle.
What are the Sources of Food?
Food is broadly classified into two main sources:
Plant Sources of Food – Derived from different parts of plants, such as roots, leaves, stems, fruits, and seeds.
Animal Sources of Food – Includes milk, eggs, meat, fish, and poultry products.
A balanced diet must include both plant and animal products to supply essential nutrients such as carbohydrates, proteins, vitamins, minerals, and fats.
Food from Plants
Plants are the primary source of food, not only for humans but also for herbivorous animals. Various parts of plants provide us with essential nutrients. Let’s explore the different types of plant-based food sources.
Vegetables
Vegetables are packed with vitamins, minerals, and fibres that help maintain overall health.
Roots: Carrots, radishes, turnips, and beetroot are nutrient-rich root vegetables.
Stems: Potatoes, ginger, and celery are edible plant stems.
Leaves: Spinach, cabbage, and lettuce are leafy vegetables.
Flowers: Broccoli and cauliflower are commonly consumed plant flowers.

Fruits
Fruits are naturally sweet and rich in vitamins, antioxidants, and fibres. Examples include:
Mangoes, oranges, apples, bananas, and grapes.
Cereals & Pulses
Cereals and pulses form a significant part of our diet and are an excellent source of carbohydrates and proteins.
Cereals: Rice, wheat, maize, barley, and jowar.
Pulses: Lentils, chickpeas, kidney beans, and black gram.
Tea, Coffee & Sugar
Tea and coffee are beverages derived from plants such as Camellia sinensis (tea) and Coffea (coffee beans).
Sugar is obtained from sugarcane and beetroot.
Oils & Spices
Edible Oils: Extracted from seeds of mustard, sunflower, and castor plants.
Spices: Used to improve flavour, including cinnamon, cardamom, pepper, cloves, and cumin.
Food from Animals
Animal-based foods are rich in proteins, essential vitamins, and minerals. Let’s explore some key animal food sources.
Milk & Dairy Products
Milk is often called the ideal food as it contains proteins, calcium, and essential vitamins.
It is obtained from cows, buffaloes, goats, and camels.
Dairy products include cheese, butter, yoghurt, and paneer.
Eggs
Eggs are a protein-rich food obtained from hens, ducks, and quails.
They provide essential nutrients like phosphorus, iron, and vitamin B12.
Meat & Poultry
Red Meat: Derived from cows, goats, and pigs, rich in proteins and fats.
White Meat: Includes chicken and fish, which are lower in fat and easier to digest.
Fish: A great source of omega-3 fatty acids, beneficial for brain and heart health.
What are the Five Primary Sources of Food?
The five primary food sources include:
Plants (Vegetables, fruits, cereals, and pulses)
Animals (Meat, dairy, eggs, and seafood)
Fungi (Mushrooms, yeast used in bread and beer)
Microorganisms (Bacteria used in making curd and probiotics)
Aquatic Sources (Seaweed, fish, and shellfish)
Importance of a Balanced Diet
A balanced diet ensures the intake of essential components of food, including:
Carbohydrates (Energy source – found in rice, wheat, and sugar)
Proteins (Growth and repair – found in pulses, eggs, meat, and fish)
Fats (Energy storage – found in dairy, nuts, and oils)
Vitamins & Minerals (Boost immunity and overall health – found in fruits, vegetables, and dairy)
Water & Fibre (Essential for digestion and hydration)

FAQs on Sources of Food: Animal and Plant Products | Best Sources of Food Explained
1. What are the two main sources of food for living organisms as per the Class 6 syllabus?
According to the CBSE syllabus for Class 6, the two main sources of food for all living organisms are plants and animals. Plants are known as producers because they make their own food, while animals depend on plants or other animals for their nutrition.
2. What are the different parts of a plant that we consume as food? Please provide examples.
We eat various parts of different plants as food. The main edible parts include:
- Roots: Carrot, radish, beetroot, and turnip.
- Stems: Potato, sugarcane, and ginger.
- Leaves: Spinach, cabbage, lettuce, and methi (fenugreek).
- Fruits: Mango, apple, banana, and tomato.
- Seeds: Rice, wheat, maize, pulses (dal), and mustard.
- Flowers: Cauliflower and broccoli.
3. Can you list some common food products we obtain from animals?
Animals are a major source of nutrient-rich food. Common food products we get from animals include:
- Milk: Sourced from cows, buffaloes, and goats, which is also used to create dairy products like cheese, butter, and curd.
- Eggs: Primarily obtained from hens and ducks, which are rich in protein.
- Meat: Such as chicken, mutton (from goats), and fish.
- Honey: A sweet liquid made by honeybees from the nectar of flowers.
4. What are 'ingredients' in the context of food, and why are they important?
Ingredients are the individual food items or materials that are combined to prepare a specific dish. For example, the ingredients for making vegetable curry are different vegetables, salt, spices, oil, and water. They are important because the choice of ingredients determines the final taste, texture, and nutritional value of the food.
5. How are herbivores, carnivores, and omnivores different from each other based on their food habits?
Living organisms are classified into three groups based on their eating habits:
- Herbivores: These are animals that feed exclusively on plants and plant products. Examples include cows, deer, and goats.
- Carnivores: These are animals that feed on the flesh of other animals. Examples include lions, tigers, and snakes.
- Omnivores: These are animals that consume both plants and animals. Humans, bears, and crows are common examples of omnivores.
6. Why is it said that plants are the ultimate source of food, even for carnivores?
This is because of the concept of a food chain. A carnivore, like a lion, might eat an herbivore, like a deer. The deer gets its energy by eating plants. When the lion eats the deer, it is indirectly getting the energy that the deer originally obtained from the plants. Therefore, all energy in a food chain ultimately traces back to plants, which produce food using sunlight.
7. Why is it important to consume food from both plant and animal sources for a healthy life?
Consuming food from both plant and animal sources ensures we get a balanced diet with all essential nutrients. Plant-based foods are excellent sources of carbohydrates, vitamins, minerals, and fibre. On the other hand, animal-based foods are typically rich in proteins and fats. A combination of both helps in proper growth, energy supply, and protection from diseases.
8. Are human beings classified as herbivores, carnivores, or omnivores? Explain your reasoning.
Human beings are classified as omnivores. The reason is that our diet consists of both plant products (like grains, fruits, and vegetables) and animal products (like milk, eggs, and meat). Our bodies are adapted to digest and derive nutrients from this wide variety of food sources, which helps us maintain a balanced nutritional intake.
