Solution
The 3 prepositions given for the transfer of energy in an ecosystem are:- The energy in an ecosystem is derived from the sun. Plants capture this energy by the process of photosynthesis.
- Plants produce energy by the process of photosynthesis, approximately 10% of the energy is stored in their tissues during this process, available for consumption by a grazing herbivore. The primary consumers get 10% of the energy inside the plants when they eat them and the secondary consumers get 10% of the energy in the primary consumers they eat. This is called the ten per cent rule, according to which each energy level only gets 10% of the energy available before it.
- Decomposers process large amounts of organic material and return nutrients to the ecosystem in the inorganic form. It is then taken up again by primary producers. However, energy is not recycled during decomposition, but rather is released, mostly as heat.
