Flora classifications depend on many factors, including region, climate, and time period.
The term flora is often used to encompass all the plants, fungi and algae in a given environment, while fauna refers to the animals that live there. The scientific definition of flora and fauna is the plants and animals that live in a certain area or time. The difference between them stems from whether plants or animals are being discussed.
In botany, or the study of plants, flora actually has two distinct definitions. Firstly, it can mean the plants of a particular environment or period of time, as listed above, or it can refer to a book or work that describes plants for the purpose of identification. This first definition is the most common and refers specifically to plant species that are native to the area or time. An indigenous species, whether plant or animal, is one that originated in an area and continues to grow and survive there without any interference from man. The opposite of indigenous species are introduced ones.
Fauna refers to animals in a specific environment, such as deer and other creatures in a forest.
Both flora and fauna have additional classifications or subdivisions. Flora classifications depend on the region, climate, environment and period of the described plants. Fauna subdivisions are mainly based on where the animals live and their size.
There are many different regions of flora across the planet. Some regions can be as large as entire continents or as small as swamps or mountainous regions. In addition to geographic areas, climate and time periods can group different plants into floras. Plants can also be grouped into native, agricultural and garden and weed flora.
Flora means the plants, algae and fungi of an area, like the grass of a swamp.
There are seven different subdivisions of fauna that are used, based on where the animals occur and their size. Infauna and epifauna are aquatic animals that live in or on the ocean floor, respectively. The microfauna is microscopic in size, while the meiofauna is slightly larger and lives in both retail and freshwater environments. Macrofauna are tiny soil organisms, larger than meiofauna but smaller than earthworms and nematodes, which are part of the mesofauna group. Megafauna are the large animals of the particular environment being discussed.
Earthworms are considered part of the mesofauna group.
Both the flora and fauna of a region are studied separately and together by many different types of scientists. Botanists, or plant scientists, mainly study the flora, while zoologists study the fauna. Ecologists and those who study conservation look to the two together, as the two groups depend on each other for survival.
