Learning objectives – to learn how food is produced and how the process

                                           is made more efficient As you move up the food

                                           chain as explain earlier, energy is lost to the

                                           environment. Therefore it is more efficient to use

                                           land to grow crops than to breed animals as growing

                                           crops involves less stages in the food chain.

 

One way in which famers make the process of breeding animals efficient, is

by restricting energy lost by farm animals. Chicken and pigs are often kept in

small cages, indoors, to prevent them wasting energy on movement or

maintaining body temperature.

 

Therefore the farmers can make the animals grow faster, which means cheaper

meat for the consumer in the supermarket.This way of producing efficient food

has many disadvantages.
