Take a look around! What do you notice? Plants? Flowers? Butterflies? Bees? Insects? Water? Have you ever wondered why they’re here? Do you believe they live in another universe, one that is different from ours? They are, after all, a part of our world. The organism is the biosphere’s basic unit. Populations are formed by […]

When it comes to human life, the environment can be defined as the sum total of all the living and non-living elements, as well as their effects on it. While all living or biotic elements include animals, plants, forests, fisheries, and birds, nonliving or abiotic elements include water, land, sunshine, rocks, and air. Nonliving or

Entamoeba is protozoan parasites that generate pseudopods and belong to the phylum Amoebozoa, class Archamoebae, and family Entamoebidae. Entamoeba has at least seven species that can live in the human gut (E. histolytica, Entamoeba coli, Entamoeba hartmanni, Entamoeba polecki, Entamoeba dispar, Entamoeba moshkovskii, and Entamoeba bangladeshi) and one that can live in the oral cavity

The environment is what surrounds us. Ecosystems are the interactions betweenThe environment is the space in which all living things exist and thrive. The environment is the place where living things live. An ecosystem is a community in which biotic and abiotic elements coexist and interact with one another.People study ecology because it looks at

Lumbricus Terrestris is relatively large,generally 110 to 200 mm (4.3 to 7.9 inches) and about 7 to 10 mm (0.28-0, 39 inches). It has about 12017 segments, often 135150. The body is cylindrical with the body, except for the rear and flattened back. Deep brown next to reddish brown and the back declining to his

In ecology, the term habitat refers to the collection of resources, physical and biological characteristics that exist in a region in order to sustain a species’ survival and reproduction. The habitat of a species can be thought of as the physical expression of its biological niche. Thus, “habitat” is a species-specific term, distinct from concepts

Biology and life science are two distinct academic fields. Biology is the scientific study of life and living organisms, whereas life science is a broader term that encompasses any scientific study of life. Biology is the more specific field of study, with many different branches such as anatomy, physiology, ecology, and genetics. Life science, on

The term adaptation dates back to the early 17th century, when it was used to describe a relationship between design and function, or how something fits into something else. In biology, this generic concept has been hijacked, and adaptation now has three distinct interpretations. First, an animal or plant can adapt physiologically by adjusting to

Cultural landscapes in the countryside, forests, urban areas, and cities, fixed archaeological structures on land or water, constructions and built environments from various eras, as well as bridges, roads, power lines, and industrial and port areas, are examples of human-shaped cultural environments. On the one hand, cultural settings are a nonrenewable resource, yet they are also

Bacteria (also referred as Eubacteria), Archaea, & Eukarya are the three realms of life. Microorganisms make up the Bacteria and Archaea, whereas plants, animals, plus microorganisms like fungi and protists make up the Eukarya.  Because they lack a nucleus, Bacteria and Archaea have been lumped together and dubbed Prokaryotes, however the Archaea are more closely
