(b) State four ways in which agriculture and industry are interrelated
(c) Give one function of each of the following parts of a disc plough
(i) disc (ii) beam (iii) furrow wheel (iv) disc scraper (v) hitch
(d) State four disadvantages of animal power
(a) Non-governmental agricultural organisations in West Africa
- West African Rice DevelopmentAgency/Association (WARDA)
- International Institute for Tropical Agriculture (IITA)

(b) Ways in which agriculture and industry are interrelated
- Agriculture provides food, clothing and shelter for those who work in the industry
-Agriculture provides raw materials for industries
- Agriculture provides market for industrial prod-ucts/goods such as tools, machinery
- Agriculture promotes industrial labour
- Industries add value to agricultural produce by procesing, storing, packaging and transporting them to final consumers
- Agro-chemical industries produce fertilizers, pesticides, herbicides, fungicides, drugs and feed additives which boost agricultural production
- Seed industries provide agriculture with viable and high yielding seeds
(c) Functions of parts of a disc plough
(i) disc: It cuts into the soil and turns it over
(ii) beam: Disc standards are connected to it/ Holds disc in position/provides additional greater depth
(iii) furrow wheel: stabilises the disc plough/keeps furrows wall clean (iv) disc scraper: removes soil from the disc
(v) hitch: point of attachment to the tractor
(d) Disadvantages of animal power - Animals are susceptoble to diseases and death
- power output is low
- animals can get fatigued
- animal power is not suitable for large scale production
- the use of animal power is restricted to certain climatic zones e.g tse-tse fly free zones
- animals cannot perform optimally at certain times of the day especially during hot weather
- poor handling of animals may cause poor per-formance/animals may refuse to work when poorly handled
- animal power cannot be used to perform certain farm operations such as harvesting and processing of farm produce as they may eat up the farm produce
