Answer:
Option B, chemical energy to thermal energy
Explanation:
All living organism feed on food that contains energy in the form of chemical energy. Once the food is intake and processed for fulfilling energy requirement of all metabolic processes with in a cell, the remaining energy is released as heat (thermal energy). Thus, an amoeba while consuming a sugar molecule converts chemical energy with in the sugar to thermal energy in the form of energy molecules.
Hence, option B is correct
An example of an alternate path in the rock cycle could be sedimentary rock goes through melting and becomes magma.
You should post the diagrams but basically there are more cells than tissues and more tissues than organs
