Food: Where Does It Come From?
Sources of food from plants and animals; herbivores, carnivores, and omnivores.
Chapter Overview
This chapter explores the sources of food — plants and animals — and how agriculture provides our staple diet. You learn about food habits of different organisms, parts of plants we eat, and the journey from farm to plate.
Sources of Food
- Plants: cereals (rice, wheat), pulses, fruits, vegetables, spices, oil
- Animals: milk, eggs, meat, fish, honey
- Herbivores eat plants; carnivores eat other animals; omnivores eat both
Edible Parts of Plants
- Roots: carrot, radish, sweet potato
- Stems: potato, sugarcane, ginger
- Leaves: spinach, cabbage, mint
- Flowers: cauliflower, broccoli, banana flower
- Fruits: mango, apple, tomato
- Seeds: wheat, rice, pulses (gram, moong)
Food Producers
Farmers grow crops; beekeepers produce honey; dairy farmers rear cattle for milk. Food from animals often depends on plants — cattle eat fodder, hens eat grains.
