<span><span>Here are the levels of biological organization:
</span><span>
1.</span>Atom:<span> Basic unit of all matter. (Take note that these are also made up of subatomic particles) Each atom has a property of a specific element.
2.</span>Molecule:<span> A molecule is a group of atoms held together by a chemical bond (Covalent bond to be specific). They differ from ions because they lack an electric charge.
3.</span>Organelles:<span> Organelles are components of a cell. Such examples would be the nucleus, golgi apparatus, Endoplasmic reticulum and the like.
</span>
4. Cell: <span>Also known as the building blocks of life. They are the most basic structural, functional and biological unit of all living things.
</span>
5. Tissue: <span>This is an aggregate of similar cells. They need to be similar cells because they all work towards a specific function.
</span>
6. Organ: <span>an organ is a group of tissue that shares a specific function.
7.</span>Organ system:<span> It is a group of organs that work together to do one or more physiological function. Each system has a specific role in the body.
8.</span>Organism: <span>It is a living creature that is composed of a network of different organ systems that work together to sustain life.
9.</span>Population: <span>It is a group of similar organisms that live in a common area or environment at a given time. A population can fluctuate depending on certain factors.
10.</span> Community:<span> Is a group of different organisms that interact with each other in a certain area or environment at a given time.
11.</span>Ecosystem: <span>It can be defined as the interaction between the different communities, including the interactions with non-living elements in an environment like water, air, temperature and the like.
12.</span>Biome:<span> It refers to a large geographical area where ecosystems exist where the organisms are adapted to the specific environment. Examples would be desert, tundra, forest and the like.
13.</span>Biosphere:<span> Encompasses all the ecosystems. In other words, it consists of all the living and non-living things in the world. </span></span>
The third one is correct.......
Personal Hygiene is very important. If you do not take care of yourself the bacteria & stinche building up will become sickening to you and others.
