Ecology is a branch of biology that focuses on the study of living organisms into the natural environment. Environmentalists give a glimpse of how organisms interact with the environment and each other, studying the complex and interrelated systems that influence life on Earth. Ecology is also known as the biology of the environment, and there are a number of subdisciplines within this branch of science dealing with specific topics of interest, such as the relationship between human beings and the natural environment. Ecology researchers studied individuals, populations, communities and ecosystems. In each level, there are more things to learn. The natural environment or biome is usually closely related among themselves; researchers can focus on a single population of plants or animals, for example, where are lot subject to study, ranging from the way in which population used their physical environment to the way in which other agencies interact with him. For example, populations of ruminants can create roads and water wells, giving way to the Earth, and may also affect plant populations due to the consumption of some species of plants, leaving others alone.Also be student as these animals affect the excretion of seeds so that plants can spread. In the 20th century, environmentalists were especially interested in human activities that had a detrimental effect on the environment, recognizing that human beings could have an influence not always beneficial in nature.
For example, pollutant discharges into the waters of a river can cause a variety of changes in the nature, as well as the paving of more than one wetland can eliminate a habitat and put pressure on animal and plant species that are accustomed to live there. Environmentalists have been interested in the study of ecosystems and integers, and also in the study of all organisms that live in them and influencing them. Each ecosystem is home to plant and animal species, many of which to the edge of the extinction of species, unique which have adapted to the environment and among themselves, the study of this scientists provides information about the history of this ecosystem, and the evolutionary roots of the animals that live there. Ecology can also be studied in urban environments. The study of ecology is not limited to the terrestrial environment; marine environments, lakes and streams can also provide a lot of topics for thought and inspiration for your study. The marine environment, in particular, is not understood very well, researchers constantly say there is no more to learn about the ocean, the creatures that live there, and its geography and the underlying geology. For example, for centuries people assumed that the bottom of the Ocean was inactive and bleak, but in the 20th century, researchers discovered areas of biological activity around hydrothermal vents, with agencies that had adapted to an environment with little dark, high, pressure oxygen in the depths of the sea.
