Difference Between Flora and Fauna

Both are set of living things and integral parts of an ecosystem. The term is flora is used for plant species, while fauna is the term used to categorize animals. Generally, both exist in almost the entire world and both sets of species respond to specific characteristics according to the geographical and climatic conditions of the region in which they develop, therefore, they are organisms that have evolved and adapted to their environment. The basic difference between flora and fauna is that flora is the plant life that exists in a particular region, generally the life of native plants of natural origin. On the other hand, fauna is the all life of animals in any particular region. The term fauna refers to a typical collection of animals found at a specific time or place. Let’s see how flora and fauna differ from each other.

This article can help you understand the concept of flora and fauna.

Difference Between Flora and Fauna In Tabular Form

Sr. No. Flora Fauna
Definition They refer to the natural vegetation (Plants life) found in a particular region or geographic area, including plants, algae, and fungi. They refer to all animal life present in the geological period, habitat, area, and region.
Autotrophs/Heterotrophs These are autotrophs, while they can prepare their food through photosynthesis. The fauna is heterotrophic while cannot prepare their food and depend directly on the flora for food.
Locomotion Immovable They can move from place to place in search of food and shelter.
Chloroplast Cell wall present in plants. Absent in animals.
Cellular wall In Plants, the cell wall is present. The cell wall is absent in animals.
Development It is the first life form to appear on earth. While they occurred on earth after flora, as they depend on flora for food.

Flora Vs. Fauna – Overview

The Earth is the only planet in the entire universe that can support life while on other planets life cannot possible. In fact, it is the origin of millions of life forms. The variety of plants and wildlife in the world is called biodiversity. Wherever we research, we find a different variety of plants, flowers, birds, insects, animals, and other microorganisms. You may have noticed that there are many plants and animals that are found only in the particular region, that is, they cannot be seen in other areas of the earth. These animals and plants are known as the flora and fauna of that area.


They refer to the set of plants that inhabit or are present in a region (for example, a continent, climate, mountains, etc.); everything which is related to it, such as their description, their abundance, the flowering periods, etc; they vary according to the climate where it develops. It is the set of plant species that can be found in a geographic region, that are typical of a geological period, or that inhabit a specific ecosystem. The flora attends to the number of species whereas the vegetation refers to the distribution of the species and the relative importance, by the number of individuals and size, of each one of them. It is a botanical term that means a varied range of plant life found in a particular place. However, the flora, depending on the climate and other environmental factors, determines the vegetation. There are many products arising from the use of flora, among the products are the raw material, such as wood, seeds, leaves, bark, rubber, fruits, and food.

Classification Of Flora

Its classification is mainly based on the environment in which its presence is natural:

  • Native flora – Belong to a particular region or location of plants species are known as native flora
  • Agricultural flora –  Plants that are grown on purpose by humans, that is, to satisfy their needs.
  • Horticultural flora –  planted by humans for decorative purposes is known as Horticultural flora.
  • Weed Flora – The unwanted plants that grow alongside the main plants is known as weed flora.


They refer to the set of animal species that inhabit or are part of a geographic region, and that are typical of a geological period. Fauna species depend on both abiotic and biotic factors. Among these, the possible relationships of competition or predation between species stand out. Animals are often sensitive to disturbances that alter their habitat; While a change in the fauna of an ecosystem indicates an alteration in one or more of its factors.

Classification of Fauna

Fauna species can be classified into the following categories:

  • Cryofauna – Found in cold places.
  • Cryptofauna – They cover those organisms that are protected in hidden microhabitats.
  • Megafauna – Large animals found in a particular area or period.
  • Microfauna – These organisms that are very small in size fall into this category.
  • Infauna – These organisms are present in the lower part of a body of water, mainly oceanic sediments.
  • Epifauna – They are aquatic animals found at the bottom of a body of water.

Key Differences

Flora and fauna can differ from each other clearly drawn on the following reasons:

  • Flora can be defined as the plant life of a specific geographic location, or in a certain period.
  • While fauna refers to wildlife, including birds and microorganisms found in a certain region or period.
  • The flora makes its own food, through the process of photosynthesis.
  • While fauna cannot make their own food and depend on plants for food, such as herbivores and omnivores.
  • When it comes to mobility, the flora is immobile.
  • While fauna can easily move from one place to another.
  • The study of flora is carried out in botany. On contrary, we study fauna in zoology.
