True or false? as the energy is transferred from producers to consumers, energy is gained.

False.

Explanation:

The food chain may be defined as the sequential tropic levels in which the organism eat other organisms and itself being eaten by other organism. Food chain do not exist in nature.

According to the 10% energy law, the energy is lost from one tropic level to the another tropic level. The 10% energy is available to the next tropic level and the remaining amount of energy is lost as heat. No energy gain occurs as the transfer of energy takes place from the producer to consumer.

Thus, the answer is false.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
