When the food relationship in a habitat are illustrated by means of diagram, the result is always a complicated web like pattern. This is due to the fact that

2 producer organisms always outnumber the consumer organisms
3 matter is lost in an ecosystem as it moves from producers to consumers
4 both consumers require oxygen for metabolic processes
