The source of resources from living things comes from plants and animals. The resources from plant sources include cash crops and food crops, dyes, and drugs while resources from animals include hide and skin, and dairy products. Plants’ resources are grown in the garden and farms for food, commercial purposes, and aesthetic values. Resources from plants are grouped into four major groups; cash crops, food crops, dye/textile and drug/medicinal crops.

Dyes are liquid substances of plant extracts that are used to change the colour of clothing materials, hair and houses.
They are extracted naturally from flowers and leaves of plants. Crops for textiles are used for making clothes by textile industries. Textile crops are cotton while fibres plant, flax guinea-hemp, sisal and jute are used in rope production. The leaves and fronds of palm trees provide materials for making hats, bags, and baskets.
Drugs are chemical substances of plant extract used as medicine to prevent or cure various health problems and diseases. Drugs are capable of altering behaviours when they are abused . Drugs are resources from the stem, roots and leaves of plants. For example Cinchoma species, garlic species e.t.c
Resources from animals
Animal resources are very important for human beings since they provide food for growth and development such resources include hide, milk, feathers and the face of livestock.
Hide and skin are derived from the skin of large animals such as camels, buffalo, cattle etc. Hide can be sold, bought or used in leather industries for the production of shoes, bags,purses, belts and garment. The skin of small animals such as goat and rabbit are edible.
