RESOURCES FROM LIVING THINGS

Resources are useful things or materials we derive from living things or non-living things. These living things are plants and animals.

 RESOURCES FROM PLANTS

There are crops that we grow for their leaves, fruits, stems and roots. We can identify four major types of plant resources. These are: food crops, crops for textiles, wood crops, and medicinal plants.

Food Crops

• Leafy Vegetables: These are plants grown for their leaves. These are either cooked or eaten fresh as salads. They provide us with minerals (calcium and iron) and vitamins (particularly vitamins A and C) which our bodies need. Examples include lettuce, cabbage, bitter leaf, pumpkin leaf, Talinum, and other plants used for ‘leafy soups.
• Fruits: Examples are peppers, tomatoes, okra, mangoes, bananas, pawpaw, dates, oranges, lemons, pineapples and guavas. They provide the body with mineral salts and vitamins.

Seeds: Examples of seeds include beans, maize, millet, sorghum, rice, barley, and wheat. We eat many of them as cooked foods. They provide us with starch, fat, and protein. We use barley for brewing beer, and wheat to make flour used in baking bread and cakes. We also use sorghum, and maize to make some local drinks
