What Is Macro Biology?

Macrobiology is the branch of science that studies large living organisms, or macroorganisms, which are any organisms visible to the naked eye. Optical instruments are not necessary to view macroorganisms, which include organisms such as mollusks, crustaceans and snails.

Through macrobiology, it is easy to see how each creature plays an important role in its ecosystem, such as soil and compost. Microorganisms are responsible for the chemical breakdown of matter in soil while macroorganisms such as earthworms grind or chew the matter into smaller pieces. Bugs, nematodes, earthworms and larger creatures make up some of the groups of macroorganisms.

The opposite of macrobiology is microbiology, which is the study of microorganisms such as bacteria, viruses and other organisms that are not visible to the naked eye. Earthworms are one example of a macroorganism that shares a strong relationship with a microorganism. Bacteria living in soil digest matter for worms, which the worms then digest into matter suitable for consumption by bacteria. Earthworms also consume bacteria, continuing the cycle.

Insects are macroorganisms that also help break down organic matter into healthy ingredients for soil. Macrobiology shows that other macroorganisms such as frogs and shrews also play pivotal roles in maintaining healthy soil.
