the environment  Energy on earth originates from the sun. What
about undersea thermal vents? Energy on Earth allows life to
exist. The sun facilitates the movements of air and water in the
atmosphere. The sun also facilitated the formation of non-
renewable resources such as oil and coal. Green plants at most
capture 1/20 of the suns energy that reaches Earth. Plants use
most of that energy for metabolisms and therefore only 1 % of
energy is converted to plant tissue.  Energy flow can be
depicted in a food chain.  Plant  herbivores  carnivores
Decomposer Organisms  Energy has allowed man to become more
industrialised and even allowed man to travel to the moon!
Because of energy loss, biomass normally diminishes through the
stages of secondary and tertiary produ
