Explain the difference in the movement of energy and matter in ecosystems.
There is a recycling of matter in ecosystems while there is no recycling of energy. Some matter, both organic matter and inorganic matter, flows through an ecosystem, e.g. migration of animals to another area, seed dispersal, ash from a fire carried by the wind or soil particles from weathered rocks moves to another area. Energy only flows through the ecosystem, e.g. energy enters as light and leaves as heat.
