4.7 Energy Efficiency



·         Pyramid of energy is the image of 100% is producer, 10% is primary consumer and 1% is secondary consumer.
·         So, the percentage that is for producer, primary and secondary is for their body parts and tissues.
·         The reason is the primary has to walk around and find food and carry out the process of “respiration”.
·         For example, mice cannot digest cellulose so; the plant cell wall can’t be digested. So, it contains energy that is lost in a form of faeces undigested material.
·         They all die and decompose so, they would call decomposers.
