Fauna and flora are two very distinct elements. In biology, the distinction is made between the study of plant life and the study of animal life. We will develop for you the notions of fauna and flora, in order to help you not to confuse them anymore. Good reading!

General Topo on Fauna and Flora
Fauna and flora are generally part of the biota, which refers to any form of complete life. This biota includes animal life forms and plant life forms. Science distinctly classifies fauna and flora for the simple reason that biological community requires this distinction.

Both fauna and flora evolve within distinct ecosystems, which allow interaction between them. Flora interacts with fauna and vice versa. One serves as a food or life environment for the other, in an incessant cycle: the cycle of life.
Thus, flora and fauna are both part of the Living, otherwise called the category of eukaryotes, with its specifics. Flora and fauna contribute greatly to the balance of ecosystems through a system of eternal cycle and renewal. Nothing loses, everything is transformed and created again.
A disappearing form of life participates in the appearance of another form of life , and vice versa, in an incessant rotation between fauna and flora.
Wildlife refers to all forms of life animal existing or have existed on planet Earth. Wildlife is studied in all regions and geographical areas combined. Today, fauna evolves in particular ecosystems, in climates favourable to their development, which is a major common point with flora.
Fauna includes all species of insects, animals and birds identified so far.
Fauna is studied according to the presence of this or that animal in this or that geographical area. The term fauna comes from the species classification system, developed by a Swedish zoologist named Carl Von Linné .
Different types of wildlife
Today, wildlife is classified into subcategories: microfauna, megafaune, mesofauna, avifauna, piscifauna and cryofauna.
The megafauna includes all the large animals living on Earth. The microfauna includes the smallest animals as well as microorganisms.
Mesofauna includes invertebrate animals and all animals living in the soil.
All bird species are grouped within the avifauna, while fish species are grouped within the fish fauna.
Finally, animals living near the ice, especially in the polar regions, are part of the cryofauna .
The so-called flora corresponds to all the plants and vegetation that exists or has existed on planet Earth. Plant life forms such as meadows, forests, trees, plants, flowers are assimilated to flora within an ecosystem animated by these same species.
Flora is studied on specific geographical areas and classified according to habitats, descriptions, geographical distributions, flowering periods, climate, etc.
Among the flora, we also distinguish the breeding times of plants and the many families to which they belong, or the number of chromosomes of each species.
Today, we can advance to say that without the flora, nothing would survive on Earth . Plants are invaluable resources and serve as a raw material for the feeding of living beings, whether human or animal.
Plants are also used for the manufacture of many medicines, and actively contribute tothe balance of the ecosystem by causing rains or protecting soils from too rapid erosion.
The different types of flores
Flora includes many subcategories, including horticultural flora, native (or endemic) flora and weed flora.
Horticultural flora is the flora that is openly cultivated by humans. The native flora is the other name given to endemic flora, ie particular to certain geographical areas, in a natural and unforced way (no introduction of species).
The flora of weeds includes all species of plants that are not desired by humans. This ranking is necessarily subjective and invites reflection.
There are 400,000 species of plants identified, and the rest of the flora to be discovered on earth is estimated at 10%. Major discoveries are regularly made in remote places: what to marvel at!
Points common between flora and fauna
Flora is essential to the proper functioning of the planet, as is fauna . There are many common points between fauna and flora; here are some of the most obvious:
- Fauna and flora breathe the air
- Fauna and flora are forms of life
- Both fauna and flora have reproductive capacity
- Fauna and flora are made up of cells. These cells are either animal or plant
- Fauna and flora can only develop by certain stimuli, which make them grow and complete their life cycle
- Fauna and flora are in constant exchange with their environment and the ecosystem that sees them appear and disappear
- These exchanges are made, for fauna and flora, in a different way
- The notion of predation is present in flora and fauna, at scales
For example, it will be interesting to study, at a specific location, the interactions between fauna and flora , as well as all possibilities, impossibilities or assumptions. The scientific community is fascinated by fauna and flora.
Differences between flora and fauna
There are many differences in fauna and flora. Beyond the simple plant and animal duality, here are some points of difference to remember between fauna and flora:
- Flora refers to any natural vegetation (including plants, mushrooms, algae)
- Wildlife refers only to animal life
- These two notions are not studied in the same disciplines: you have zoology and botany to differentiate studies from these specificities
- Flora is able to feed thanks to light and sun, making its food. Wildlife is the consumer and directly depends on the presence of flora.
- Flora and fauna are interdependent, but not exclusively
- Flora appeared long before the fauna: it is moreover the first form of life on earth
- Flora is not supposed to be mobile: it is anchored somewhere, while fauna is mobile by nature
- At the cellular level, the plant cell has a cell wall and chloroplast. Animal cell has no cell wall but has mitochondria instead of chloroplast
The world is usually driven by all these forms of life. The difference is also the richness of an ecosystem , and its variety is even more studied in remote parts of the Earth. Water, the environment, the region, the climate in the world or simply in France are factors of presence or absence of life that it is fascinating to study.
Plant and animal populations are regularly listed by zoologists and biologists . With changes in climate and ecosystems, the environment changes and some species disappear. Others are threatened, whether at the plant or animal level.
Biodiversity is one of the major challenges of the twenty-first century, trying to protect what remains to be protected. For some environmentalists, fauna and flora are victims of the point of no return reached by humans in their exploitation of the planet’s resources.
The study of fauna and flora continues to show us, in the long term, the consequences of human presence on Earth, as well as possible actions in favor of biodiversity.
