How do the animals in an ecosystem mainly acquire the sun’s energy?

a) they absorb energy through their skins.

b) they obtain energy when they drink water.

c) they obtain energy trapped and stored by plants.

d) they can convert the sun’s energy into chemical energy.

Option C, They obtain energy trapped and stored by plants.

Only plants or all green chlorophyll containing organisms have the ability to trap suns energy and produce food for themselves and all other organism on the planet earth.  

Therefore in every ecosystem plants lie at the base of all trophic system.  

When an animal feed upon plant or its produce nearly 10% of the energy is transferred to them.   Like wise, all organism receives only 10% of the energy from the organism or plant which they eat.
