Which way should the energy arrow point?
Connect energy arrows from food to consumer.
Energy moves from a consumed organism to its consumer. Some is dispersed as heat at every transfer. Decomposers obtain energy from dead organic matter and help return nutrients to the environment. Nutrients cycle; usable energy flows through.
A small illustrative feeding chain with decomposers receiving dead organic matter. 10% transfer is a teaching example, not a universal constant. Energy flows; nutrients cycle.
Carry energy from grass to rabbit to fox, with a separate decomposer link.
Trace energy from food to consumers and decomposers.
