List the hierarchy of cell organization from largest to smallest

The answer is;

Biosphere > Biome > Ecosystem > Community > Population > Organism >  Organ System > Organ > Tissue > Cell > Organelle > Molecule > Atom.

This is a clear representation of the complexity of life on earth. Over the course of evolution, abiotic elements developed into biotic elements then to unicellular organism and finally to complex multicultural organisms.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
