Answer with Explanation:
The<u> death of plants in water</u> increases the presence of <em>"organic matter</em>." Bacteria feed on organic matter and decompose it, thus, <em>the sudden presence of organic matter signals the bacterial activity to increase. </em>The number of bacteria increases through <em>"binary fission,"</em> which happens in fast rate. Their response to<em> food</em> (organic matter) is <u>very rapid</u>. Once they're able to decompose it, the growth of bacteria<em> slows down</em> until it drops to a low number.

These two systems are the major organ systems that mainly regulate, communicate, and control the entire body systems and sometimes they become inter-relational.

Its not actually just one system if you look at it, there are various interdependent system that actually manages every movement of every system in order to maintain homeostasis, plainly every set function is a coordinated body system response. For example, the digestive system digests food because of the enzymes and the cells and organs present in its system but again, this is aided by the different hormones which is part of the endocrine system, interdependently. Thus eventually, the circulatory system is the organ system that intiates in dissemination of the different processed and intially metabolized nutrients in the digestive system and sent throughout the body. Incidentally, also the immune system acts as agent in again many systems to maintain the so-called homeostasis. </span>
