In an ecosystem you have Populations, which are all the animals of the same species in that area

You also have Communitys, which are all the living organisms of an area

Then, there is the ecosystem itself, which is all the living and non-living things in an area and how they interact.

Then, as you reach more broad levels you get Biomes, which area very large areas of similar climate and ecosystems, usually cover areas of hundreads of miles.

(This is an example of a tundra)

Finally, you reach the largest area type, which are Biospheres, which is all the Biomes on a planet put together.

(Everything above and on the ground, and inside the atmosphere)

And there you go, You have made yourself an ecosystem.

Biology Knowedgy was created for students, by students. We of Biology Knowledgy are here to help you with your biology needs. If you read our many linked pages, you might actually learn something... just mabye.

Link To Ecosystems

Atom- unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10-8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.

Molecule-the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
null

Homeostasis-the tendency of a system to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus tending to disturb its normal condition or function.

Nucleus- central part about which other parts are grouped or gathered; core

Here is an example of a food web, which is made up of multiple, overlapping food chains. A food chain is the order of "what eats what," For example, plankton is eaten by krill and krill is eaten by whales. If you look at a food web however, plankton is eaten by multiple organisms, flowing into their food chains. Krill is also eaten by other organisms, making it part of multiple food chains, then in other food chains, other organisms can be eaten by multiple organisms as well making one organism part of multiple food chains. (the arrows show the direction energy flows)

The most common branches of biology are as a follows:

Botany is the study of plants.

Genetics is the study of genes.

Zoology is the study of animals.

This is fun isn't it?

Ecology is the study of plants and animals in relation to their total environment.

Anatomy is the study of the structure of living organisms.

Physiology is the study of internal processes and functions associated with life.

I hope you are having as much fun as I am!!

Biochemistry is the study of the chemistry of living things.

Cytology is the study of cells.

Evolution is the study of of the ways in which present-day organisms have been produced.

Taxonomy is the study of how organisms are classified.
Microbiology is the branch of biology dealing with the structure, function, uses, and modes of existence of microscopic organisms
Otolaryngologistsis the branch of medicine that deals with the anatomy, function, and diseases of the ear, nose, and throat

Wow wasn't that exciting, but you have only scratched the surface of biology. Check out our other pages to expand your brain and make your nerdy friends jealous. If ANY of these words don't make sense, come here
