| Explain various levels of biological organization? |
Ans: The various steps through which an organism is arranged are called the level of organizations. Various levels of biological organization as follow.
1. Matter and elements:
The matter is composed of a basic substance called elements there are more than 92 naturally occurring elements basic elements in human beings 99% of the total mass is formed by six elements these elements are called basic elements these are.
- Hydrogen
- Carbon
- Nitrogen
- Calcium
- Phosphorous
- Oxygen
Other elements are also present their contribution is less than 1% of total elements there are called trace elements.
2. Atoms:
Atoms are the smallest particle of matter it is composed by protein, neutron and electron.
3. Molecules:
Atom combines to form molecules.
Atom combines to form molecules.
4. Compounds:
Molecules combine to form compounds. Compounds are of two types, organic and inorganic compounds.
5. Organelles:
Both organic and inorganic compounds are associated in particular fashion at farm structure known as organelles e.g. ribosomes, mitochondria.
6. Cell:
It is the basic structure and function of life. It cautions sub cellular organelles e.g. nerve cell.
7. Tissue:
A group of a cell with similar structure and function is called tissue e.g. parenchyma and collenchymas in a plant. Nerves tissue in animals.
8. Organ:
The related tissue in a particular, fashion combines to form an organ e.g. liver, stomach.
9. Organ system:
The organs in co-ordinate in their function and form an organ system e.g. digestive system.
10. Organism:
Different system collectively forms an organism.
11. Species:
A group of closely related organism that can interbreed and produce fertile offspring in close association are called population.
12. Population:
Members of same species living together in close association are called population.
13. Community:
The different population of the same constitutes a community.
