Biodiversity can refer to the sheer variety, number, and diversity of living organisms in specific geographical locations. It describes the numerous types of plants, animals and other organisms (micro and macro) and the variations in their genetics.  The weathered material of the earth provides the base for the variation in the survival of biodiverse organisms.

Species composition “Species composition is defined as the number of different species present in an ecosystem, as well as the relative abundance of each of those species,” according to the National Wildlife Federation. When all of the species present are equally abundant in the area, the level of diversity is at its highest. There are

The life cycle of a snake varies greatly depending on the species. Some snakes lay eggs, while others give birth to live young in broods ranging from one or two newborns to litters numbering in the hundreds. Parthenogenesis is the mechanism by which some uncommon snake species lay eggs without mating. Snakes that hatch from

The scientific name of the prawn is Dendrobranchiata. Among the first shrimp subspecies discovered by scientists was the massive river prawn. The  prawn is a small aquatic crustacean with an exoskeleton and ten legs that belongs to the Decapoda group and can be eaten in some cases. Prawns are large swimming crustaceans or shrimp that

Introduction The scientific name of Parrot is Psittaciformes. According to the Integrated Taxonomic Information System, parrots are members of the order Psittaciformes, which includes more than 350 bird species such as parakeets, macaws, cockatiels, and cockatoos (ITIS). Despite the fact that there are many different types of parrots, all parrot species share a few characteristics.

The earthworms’ skin has a wet feel to it. It’s for this reason that they’re known as slimy animals. The earthworm’s skin serves as its respiratory organ, which explains their wet skin. An earthworm’s skin is porous, allowing air to travel through readily. Gases are often exchanged through its wet skin and capillaries. The oxygen

Despite the fact that amphibians and reptiles are both ancient groups of vertebrates (animals with backbones), they are distinct in a number of important aspects of their physiology, development, and life cycle.They have a variety of characteristics that distinguish them from one another, but they are all members of the same class – The Reptilia,

A plant species, which makes its food, cannot survive alone. It needs soil microorganisms to break down the organic matter and return the inorganic nutrients for reuse. Animals help the plant in the pollination and dispersal of fruits and seeds and provide carbon dioxide for the preparation of food. Animals, plants and microbes cannot live

The bulk of the world’s 350,000 flowering plant species relies on animal pollinators for reproduction. Animal pollinated plants have an essential role in ecosystems, maintaining biodiversity and providing ecosystem services such as building materials, biofuels, medicines, and food. Three-quarters of the world’s most important crops improve their yield or quality when pollinated by animals. Furthermore,

Phytoplankton are a diverse group of microscopic creatures which reside on and underneath the bodies of water such as ponds, lakes and rivers, as well as the oceans around the world. Plankton is derived from the Greek word planktos, which means to drift or float. It is not possible for plankton to swim on their
