Document Summary
Ecology is the study of how organisms interact with one another and with their nonliving environment. In effect, it is a study of connections in nature the house for the earth"s life: organism is any form of life, cell is the basic unit of life in organisms. May consist of a single cell like bacteria, or many cells. Each cell is encased in an outer membrane or wall and contains genetic material (dna) and other parts to perform its life function. Organisms such as bacteria consist of only one cell, but most of the organisms we are familiar with contain many cells. They are everywhere and there are trillions of them. Microbes also help produce foods such as bread, cheese, yogurt, vinegar, tofu, soy sauce, beer, and wine. You should also thank bacteria and fungi in the soil that decompose organic wastes into nutrients that can be taken up by plants that we and most other animals eat.
