Although it is lower in energy than the food from which it is derived, feces may retain a large amount of energy, often 50% of that of the original food. This means that of all food eaten, a significant amount of energy remains for the decomposers of ecosystems.
Image: Specialised organelles. Every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all organelles.very cell in your body contains organelles (structures that have specific functions).

The membrane-bound organelle (mini organ) in eukaryotic cells, aka those cells that contain a membrane-bound nucleus, that is the control center of the cell. The nucleus houses the genetic instructions necessary to synthesize proteins and other molecules needed for cell survival, growth, and reproduction. tubular structure that is made of protein and found only in animal cells. It is involved in cell division and the formation of flagella and cilia (types of pointy things that assist cells in what they do).
