(a)(i) What is an agricultural system?
An agricultural system is a particular method or pattern of organising and carrying out farming activities (the way crops are grown and/or animals are reared) on a piece of land to achieve production goals.

- Shifting cultivation.
- Bush fallowing (land rotation).
- Mixed farming (crops and livestock together).
- Mixed cropping.
- Continuous cropping / plantation (monocropping) system.
(b) Four ways NGOs contribute to agricultural production
- They provide credit, grants and farm inputs to farmers.
- They train farmers and provide extension education.
- They fund and carry out agricultural research.
- They help provide rural infrastructure and market outlets for produce.
(c) One function of each incubator component
- (i) Counter: records/keeps track of the number of days (turns) the eggs have been incubated.
- (ii) Thermostat: automatically regulates and maintains the correct temperature inside the incubator.
- (iii) Hygrometer: measures the relative humidity (moisture content) inside the incubator.
- (iv) Egg tray: holds/supports the eggs in position (and aids turning) during incubation.
- (v) Heater: supplies the heat needed to keep the eggs warm for the embryos to develop.
