There are many parts in Biological Diversity...
(1) The Producers
~ Producers are the beginning of the food chain.They
are plants and vegetables. Plants are at the beginning of every food chain that involves the Sun. All energy comes from the
Sun and the plants make food with that energy. They use a process called photosynthesis. Plants also make
a lot of other nutrients or foods for other organisms to eat.
(2) The Consumers
~ 2 types of consumers. Consumers and Secondary
Consumers.
Consumers
~Consumers are a link in the chain.
There are three levels of consumers. The levels start with the organisms that eat plants. They are called Herbivores
It will not eat animals.
Secondary consumers
~ Secondary Consumers eat the primary consumers. Secondary consumers are also called carnivores. Carnivore means "meat eater.There
are also consumers called omnivores. Omnivores eat anything that they can.They eat meat.
(3) The Decomposers
~The last pieces in
the chain are the decomposers.Whenever something that was alive dies, the decomposers get it. Decomposers break down the nutrients
in the dead "things" and return it to the soil. The producers then use the nutrients and elements over again once it is in
the soil. The decomposers finish the system.

Biological diversity, refers to all of the many kinds of life on Earth.
Biological diversity is used to refer all the number of different tyoes of animals on Earth. A big part of this
biodiversity would include human beings, Bengal tigers, sugar maples, oyster mushrooms, bacteria, and all of the other
living organisms found on Earth. Gradual estimates of the number of species on Earth range from 5 to7 million but some scientists
estimate as many as 30 million! With only about 1.6 to 2 million of these species having been studied (many only at the very
basic level) and given a name, a lot still needs to be learned about the diversity of life here on Earth.
A lot of the Earth's biodiversity consists in the tropics.
Scientists estimate that 50% of all species on the planet are found in tropical rainforests that consist of only 6 to 7% of
the Earth's land surface. The fast rate at which tropical rainforests are being cut, it is estimated that up to 20% of the
Earth's biodiversity may become extinct in our lifetime!
Loss of this biodiversity means we would not only lose beautiful ecosystems
but we might also lose plants and other organisms that could improve or our lives. Tropical biodiversity has also provided
us with medicines used to treat diseases as malaria.
Biological diversity is the full range of different
and changes within
and in living organisms and the
natural associations in which they happen. Biological
diversity includes ecosystem
diversity, species diversity,
and genetic diversity.
