| Question | Answer |
| fundamental particles: quarks and leptons which are the fundamental constituents of matter composed it. Species of leptons are joined to form electrons and species of quarks together to form neutrons and protons. Physics is the science that deals with the study of this area along with the Atomic and subatomic level. | |
| Subatomico: this is the simplest of all and is made up of electrons, protons and neutrons, which are the different particles that make up the atom. | |
| it is the next level of organization. It is an atom of oxygen, iron, any chemical element. At the biological level we can call the atoms as bioelements and classify them according to their function. | |
| molecules: molecules consist of the union of several different atoms to become, for example, oxygen (O2), carbon dioxide gas State, or simply carbohydrates, proteins, lipids... Molecules can be organic (glucose, lipids, fats) or inorganic (water, mineral salts, gases, oxides,...) Biochemistry deals with the study of this level of organization, being one of the most leading-edge disciplines, and that gets more research resources in research and universities within the areas of this article. | |
| subcellular structures or organelles: is not one of the levels of organization that traditionally are included since it is half way between molecules and cells. You can be considered as one further step, since it is the union of several molecules to form larger structures such as organelles of the cells: plasma membrane, Golgi apparatus... Cellular biology or cytology is responsible for the study of cells and organelles that compose them. | |
| cell: molecules are grouped into cell units with its own life and capacity for self-replication. The cells can be eukaryotes or prokaryotes depending on its structure. They can also form independent living organisms such as protozoa, and amoebas. | |
| tissue: cells are organized into tissues: adipose, epithelial, nervous, muscle... In plants we would talk about the parenchyma, for example. Histology is the science that deals with the study of tissues. | |
| Organular: the tissues are structured in organs: heart, spleen, lungs, brain and kidneys... In plants, we can speak of leaves, stem, root... | |
| systemic or appliances: bodies are structured into devices or more complex systems that carry out broader functions. We have the example of the digestive, respiratory, circulatory and nervous systems... | |
| Organization: upper organization level in which the cells, tissues, organs and operating devices form a superior organization as living beings: animals, plants, insects,... | |
| population: organisms of the same species are grouped in number to form a population nucleus: a herd of lions, and wolves, a forest of maples, pines... in addition, coincide in time and space. | |
| Community: it is the set of alive beings of a place, for example, a set of populations of different organisms. It is formed by different species. | |
| ecosystem: it is the interaction of the biological community with the physical environment, with a wide spatial distribution. Populations, communities and ecosystems are studied by ecology. | |
| landscape: it is a level of superior organization comprising several different ecosystems within a given unit of area. For example, the set of vine, olive groves and almond trees characteristic of the provinces of the Spanish Southeast called agrosystems. | |
| region: it is a level of organization superior to the landscape and represents a geographical area comprising several landscapes. | |
| biome: Are large ecosystems associated with certain environmental characteristics: macro such as humidity, temperature, radiation and are based on the dominance of a kind although they are not homogeneous. An example is the taiga, which is defined by the conifers which is an identifier element very clear but not homogeneous, is also defined by the latitude and temperature. | |
| Biosphere: it is the whole of living beings and inert components that make up the planet Earth, or similarly is the layer of the atmosphere where life exists and is supported on the lithosphere. |
