Answer: Decomposition is a process in which complex organic molecules are converted into simple inorganic forms, which can be easily degraded.
Explanation:
The watermelon is a food source for decomposers. The soft fleshy part get decomposed and degraded easily but the hard thicker rind takes long. The soil decomposers like bacteria, earthworms and fungi will convert the organic matter in the watermelon into inorganic components. This way the matter is converted into a form which can be utilized by the decomposers as a source of energy and some components also improves the quality of soil.
Exoenxymes function outside cells and endoenzymes function inside cells.
<h3><u>Explanation:</u></h3>
Enzymes are present everywhere in the body. Some of them are present inside the cells where they are produced and they function. Rest of them are produced inside the cell but are secreted outside so that they can work at their targeted place. Enzymes of Glycolysis, Krebs cycle, ETS etc , and other house keeping enzymes are functional inside the cells.
Enzymes required in the digestion like amylase, proteases, maltase, etc are required inside the gastrointestinal tract. So they are secreted form intestinal wall or pancreas into the GIT.
It is different because it depends on where the systems it came from, and which type of systems they are.
