Density-independent factors can affect a population of organisms no matter how small or large the population may be. Examples of Density-Independent Factors. Most density-independent factors are abiotic, or nonliving. Some commonly used examples include temperature, floods, and pollution. How could temperature be a factor in determining the density of a population? Imagine a heavily forested area that is home to a population of mosquitoes.
Unicellular organisms are known as single-celled organisms. They are made up of a single cell. Organisms like the amoeba, Paramecium are single-celled organisms, they are the oldest forms of life, they existed about 3.8 million years ago. Bacteria, archaea, protozoa, unicellular algae and unicellular fungi are the main groups of unicellular organisms. The single-cell regulates all the activity of the organism. Unicellular organisms are small are mostly invisible to the naked eye. There are two general categories of unicellular organisms: prokaryotic and eukaryotic organisms. Prokaryotic unicellular organisms are protists and some fungi. Some of these unicellular prokaryotes live in colonies. They live together and all the cells of the colony is the same. All the process of life is carried out in each cell in order for the cell to survive. Simplest multicellular organisms are made of cells that dependent on each other for their survival. Most of the multicellular organism are microscopic and are known as microscopic organisms. Unicellular organisms vary in size.
