Organisms/ Individuals
Definition: An organism is a living being with all the characteristics that are essential for the existence of life such as growth, development, capability to respond to any stimulus, reproduction etc.
This is the smallest level of ecology. It is also considered as the fundamental unit of the entire ecology. Organisms can be unicellular ( organisms with only one cell such as Bacteria) and multicellular (organisms with more than one cell such as Humans). Besides this, on the basis of complexity of internal body organisation, organisms can be classified into prokaryotes and eukaryotes.
Prokaryotes are the organisms that do not possess a well developed nucleus. On the other hand, eukaryotes are the organisms which possess well developed nucleus and other cellular organelles.
Five Levels of Ecology
The five levels of ecology indicate various ecological levels of organization which is necessary for the survival of life on the earth. An ecosystem also displays interactions on ecological levels between different organisms. The energy flow occurs within ecological levels as bigger organisms eat up smaller organisms. In this article, we will cover the five levels of ecology in order from smallest to largest.
