Man has always had a profound need to understand and master the knowledge of the functioning of all living beings. This has allowed him to expand the frontiers of knowledge, but above all else, to exercise dominion over a part of nature. L to biology as a science that studies living things, has served to understand the evolution of all species and to control its development work. The transcendental role of biology is given by the possibility of knowing and protecting all those living organisms that allow man to perpetuate his own species.
The Biology section , which readers will be able to navigate with ease, contains definitions, concepts and development of all the topics inherent in the study of all living beings . Animals, plants, single-celled organisms, all accompanied by excellent images so that the experience of introducing ourselves to the world of biology is exciting. Each topic is treated with rigor and simplicity, so that it can be used as a way to expand knowledge or as a complement to school tasks.
The concept of biocenosis indicates the set of living beings that inhabit or exist in a certain space called the biotope . The biotope is the one that has the function of providing and satisfying all the needs of its inhabitants so that they can survive, for example, light, water and food. This type of space can vary depending on the geographical space in which it is … Read more
There are a variety of different ecosystems around the world. Remember that an ecosystem is a group of communities of things both living and inert that are related to each other. While there are many ecosystems on earth and in the world’s waters, the terrestrial ecosystem is one that is found only on land . Biotic beings found in this type of ecosystem include a … Read more
The oceans cover two-thirds of the Earth’s surface. Within this oceanic habitat live a great variety of organisms that have evolved in response to various characteristics found around them. Marine organisms are not found uniformly in the oceans. Different characteristics of the marine environment have created different habitats that influence the types of organisms that live in them. Light, depth, proximity to land, and topographic complexity affect … Read more
An ecosystem is a unit that includes all living beings : plants, animals, organisms and non-living elements that exist within a certain area, interacting with each other, and that also interact with non-living environments such as climate, earth, sun, soil, climate and atmosphere. Ecosystems constitute the basis of the Biosphere and determine the health of the entire Earth system. In an ecosystem, each part and organism that makes it up play … Read more
The flatworms , also called flatworms , are a group of invertebrates that have their body soft , and are generally very crushed . Several species of flatworms can live outdoors , but about 80 percent of all flatworms are parasites , that is, they live on or in another organism and feed on it. Are symmetrical bilaterally so the right and left sides are similar and have systems respiratory, skeletal and circulatory specialist. The body … Read more

Roundworms that may also be called nematodes , are a kind of worms which have a body round and long . They are worms that can vary in length from several millimeters to two meters. Roundworms are common to find in hot tropical countries . Children are more often affected than adults . Treatment is usually very effective, but eliminating pinworm infections is always a rather difficult process. What are nematodes? Nematodes are organisms that live in water , … Read more
The heterotrophic organisms are those that must be fed with the organic substances that are synthesized by other organisms, either beings autotrophic or heterotrophic at the same time. To this group belong all the members of the animal kingdom , fungi , a large part of bacteria and archaea . What are heterotrophic organisms? The heterotrophic organisms are those which can not produce their own food by fixing carbon and therefore derives its intake nutrients from other … Read more
An autotrophic organism, within the branch of ecology , is an organism that serves as a primary producer within a food chain . The autotrophic organisms derive their energy and nutrients through the use of sunlight and do through photosynthesis , so they are also called photoautotrophs , and in some rare cases, obtain chemical energy by oxidation and are called chemo autotrophs to produce organic substances from inorganic substances. Autotrophs do not … Read more
The coniferous forest is the largest biome that exists on earth. The coniferous forest biome is found in the northern parts of Asia , Europe, and North America . This important forest biome constitutes approximately one third of the forests that exist around the world. What is the coniferous forest? The coniferous forest is an ecosystem that is characteristic of places with temperate climates in which hot summers and cold winters occur , as well as enough rain to maintain its characteristic coniferous … Read more
