What Does This Mean?
Agriculture provides most of the food that people eat every day. Without farming, we would have nothing to eat!
How Agriculture Gives Us Food
- Crop Farming (Growing Plants)

Farmers grow plants that we eat directly
Grains and Cereals:

- Rice – for rice and swallow
- Maize (Corn) – for corn meal and pap
- Wheat – for bread and noodles
- Millet – for local porridge
Root Crops:

- Yam – for pounded yam and boiled yam
- Cassava – for garri, fufu, and tapioca
- Sweet potato – boiled or roasted
- Cocoyam – for soup and porridge
Vegetables:

- Tomatoes – for stew and soup
- Pepper – for seasoning food
- Onions – for cooking
- Lettuce, spinach – for salad
Fruits:

- Oranges, mangoes – fresh fruits
- Bananas, pineapples – healthy snacks
- Watermelon, pawpaw – refreshing fruits
- Animal Farming (Livestock)
Farmers raise animals that give us food
Meat:

- Cattle – beef meat
- Goats – goat meat
- Chickens – chicken meat
- Pigs – pork
Dairy Products:

- Cows – fresh milk, cheese, butter
- Goats – goat milk
Other Animal Products:
- Chickens – eggs for breakfast
- Ducks – duck eggs
- Fish – from fish farms
- Processed Foods from Agriculture
Raw farm products are turned into different foods
- Rice → Cooked rice, rice flour
- Maize → Corn flakes, popcorn, pap
- Cassava → Garri, fufu, bread (cassava flour)
- Milk → Cheese, yogurt, ice cream
- Fruits → Fruit juice, jam
Why Agriculture is Important for Food
- Provides All Food Groups
- Carbohydrates: Rice, yam, cassava (gives energy)
- Proteins: Meat, fish, beans, eggs (builds muscles)
- Vitamins: Fruits and vegetables (keeps us healthy)
- Fats: Palm oil, groundnuts (gives energy)
- Feeds Everyone
- Provides food for millions of people
- Without agriculture, people would starve
- Ensures food security for the nation
- Fresh and Natural Food
- Farm-fresh foods are healthier
- No artificial chemicals in natural foods
- Better taste than processed foods
- Available All Year
- Different crops grow in different seasons
- Food storage helps preserve crops
- Continuous food supply throughout the year
