3. The diversity of ecosystems
This level of diversity can be demonstrated by the variety of ecosystems in the biosphere.
example:

moss ecosystems, tropical forest ecosystem, desert ecosystem, each ecosystem has a unique organism to ecosystem. another example, the desert ecosystem in which there are camel, cactus, and tropical forest ecosystem in which there is a tiger.

These three kinds of diversity can not be separated from one another. All three viewed as a whole or the totality of the biodiversity.

1. With the discovery of the gene is keanekaragamaan basic capital to do genetic engineering and hybridization (crossing) to obtain the expected seeds. Knowing the existence

2. types kenaekaragaman can lead us to seek alternatives to food, clothing materials, and the board, also can lead us select superior animals that can be cultivated.

3. By knowing the diversity of our ecosystem can develop biological resources that match the particular ecosystem in order to increase agricultural and livestock that in turn can improve people's welfare.

Classified into 3
1. Natural Classification System
- Created by Theophrastus (370SM - 285SM), one of the disciples of Aristotle
- Based on a form that can be seen with the naked eye (morphology)
- The plant is divided into 4 groups: trees, bushes, shrubs and herbaceous

2. Artificial Classification System
- Created by Carolus Linnaeus (1707-1778), Swedish scientist
- Known as the father of classification
- The basic tool used is sexual reproduction, other base used is morphology.
- A classification of living things based on its impact on human
- For example: toxic or useful, domesticated or wild, weed or vegetables.

3. phylogenetic classification system
- Created by Charles Darwin in 1859, published a book about the theory of evolution.
- He states that the equation shows the relationship of structure closer kinship.
- Based on the order of development of living organisms (phylogeny) and knowing of kinship with each other.

2. The diversity of species (species)

This diversity is more easily observed than the diversity of genes. This level of biodiversity can be shown by the variety of types of good living that includes groups of animals, plants and microbes.

example:

- Variations in a family of cats and tigers. They are included in one family (family / family Felidae) although there are physical differences, behavior and habitat.

Biodiversity 1. Various Level Biodiversity

1. Various Level Biodiversity

Biodiversity can occur at various levels of life, ranging from low levels of organisms to high-level organisms. Example of single-celled creatures to many-celled creatures; and organizational levels of individuals living up to the level of complex interactions, such as from species to ecosystems.

In general, biodiversity is divided into three levels, namely:
1. Gene diversity
Every living organism trait controlled by a pair of hereditary factors (genes), one of the other parent of the male and female parent. This level of diversity can be shown by the variation in one species.

example:
- Variations of coconut: coconut ivory, green coconut
- Variations of dogs: a bulldog, shepherd dog, mongrel
What makes this variation is: The formula: F = G + L

F = phenotypic
G = genoti
L = environmental

If G changed for some reason (mutation, etc.) or L changes there will be a change in F. Change is what causes this variation.
