Levels of Organization in Biology || Grade 7 Science ||

Let's go through the different levels of Biological organization. I start at the organism and finish at the Biosphere. However, the smallest level of life is a cell. Cells can combine to make tissues, which may combine to make an organ, and a group of organs may make an organ system.

An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, requires energy plus grows and adapts
Examples include animals, plants, fungi, protists, and many, many more.

Whenever you get a group of the same type of individuals together, like this group of Penguins or these wolves, and horses, or plants you have a population. The organisms are all of the same species.

If you have several different populations living together you have a community.
A community does not include the non-living factors also called abiotic factors.

An ecosystem is a community of living factors called biotic factors and non-living factors called abiotic factors interacting and living together.
A desert can be an ecosystem.
A forest can be an ecosystem.
A pond is an ecosystem,and even a rotting log can even be an ecosystem.
An ecosystem is a community of living and non-living objects living together in a particular area.

A Biome is a large ecosystem that has formed in response to the physical environment[1] in which they are found and a shared regional climate. Examples include a desert, tropical rainforest, and a deciduous forest.
The Biosphere is part of the earth where life exists. It is the sum of all the ecosystems on Earth.
