(ii) List four factors that affect feed formulation.

(b) State the energy changes in the following activities:
(i) Photosynthesis
(ii) Hydro power
(iii) Switching on a television



Answer :

Final answer:

Animal feed is the food provided to food-producing animals. Factors impacting feed formulation include species, age, and physiological state. Energy changes in photosynthesis, hydro power, and using a TV involve diverse energy transformations.


Explanation:

Animal feed refers to the food given to food-producing animals to meet their nutritional needs. Factors affecting feed formulation include species, age, physiological state of the animal, and type of feed or processing. The energy changes in: (i) photosynthesis involve the conversion of sunlight into chemical energy; (ii) hydro power utilize water flow to generate electricity; (iii) switching on a television involves electrical energy consumption.
