Marine ecosystems are the largest aquatic ecosystems on Earth and live in waters with a lot of salt in them, like the ocean. These ecosystems are very different from freshwater ecosystems, which have less salt in them. More than 70% of the Earth’s surface is covered by marine waters. They make up more than 97% […]

Ornithology is a branch of zoology that focuses on the study of birds. It is a subfield of biology. The majority of early writings on birds are more anecdotal than scientific in nature, but they provide a broad foundation of knowledge, which includes a great deal of folklore, on which later work could be built.

Introduction  All the organisms on this planet possess the capability of adapting to dissimilar and various environmental conditions. This happens because of the variation in the genes of the organisms. Due to this, their chances of survival increase. For instance, a polar bear has a body type and character traits that help in surviving in

Ecology is a discipline of biology that is primarily concerned with the investigation of the interactions that exist between organisms and their environment. Organisms An organism is a continuous biological system that exists in a given environment and has the ability to adapt and maintain a specific structure and behaviour. Fungi, bacteria, plants, animals, and

Classification enables us to better comprehend variety. It aids in the identification of living entities and in comprehending their variety. It enables us to get knowledge about the many species of plants and animals, their characteristics, similarities, and differences. It allows us to comprehend the evolution of complex species from simpler organisms. Living Organisms Classification

The world in which we live is filled with a variety of creatures, each having different bodies, functions in the ecosystems, etc. The study of all the creatures helps us understand our environment and ecosystem better and helps us classify various types of creatures. The study of various organisms also helps us understand their significance

Reflex action is an automatic, near-instantaneous reaction to stimuli. If hand accidently touches hot objects, for example, it is removes. The reflex arc is the path travelled by a stimulus as it travels from the receptor organ to the effector organ. Examples of reflex action Robert Chambers’ ground breaking work on participatory methodologies, which began

In ecology, an ecosystem is a geographical area in which plants, animals, and other species, as well as weather and topography, coexist to form a sphere of life that surrounds them. In addition to biotic (living) components, ecosystems may also contain abiotic (nonliving) components. Biotic factors include organisms such as plants, animals, and other species.

Cyanobacteria, which includes blue-green algae, are a kind of bacteria. Cyanobacteria are equipped to use the sun’s energy to make their own food in their aquatic habitat via photosynthesis. The colour, which was a by-product of the bacteria’s photosynthetic activity, and their appearance as an algal-like scum on pond surfaces gave rise to the moniker
