Ecology is the scientific study of interactions between organisms and their environment. Environmental conservation is the practice of protecting the natural environment on individual, organizational or governmental levels for the benefit of both the natural world and humans.Know More
The term "ecology" refers to any delicate or intricate system. As a science, ecology is an interdisciplinary field that includes biology and Earth science. An understanding of the effects of biodiversity is an important focus in ecological studies. The German scientist Ernest Haeckel coined the word "ecology" in 1866. Ancient historians and philosophers began the study of nature, but modern studies transformed the field into a rigorous science in the late 19th century. Ecology is closely related to evolutionary biology and genetics. Another branch of ecology known as “human ecology” concerns itself with the spacing and interdependence of people and institutions.
Environmental conservation, like ecology, is an interdisciplinary field. Academic institutions offer courses in environmental studies, environmental management and environmental history. The pressure of human activity and technology has degraded the natural environment. Since the 1960s, organizations and governments have placed restraints on activities that cause environmental degradation. There are disagreements about the extent of human impact on the environment, and some conservation methods are criticized.Learn more in Environmental Science
The law of tolerance, usually called Shelford’s law of tolerance, states that an organism’s needs must fall within a range of acceptable limits, or the organism will struggle to survive. For example, an animal may require between 10 and 20 grams of food per year to survive. The essential point of the law is that organisms can adapt to varying conditions, within rather rigid limits.Full Answer >
Producers are organisms that make their own energy. Plants are producers because they make their own food using light, carbon dioxide and water through photosynthesis.Full Answer >
There are many different types of environments, also called habitats, in which organisms live, including forests, grasslands, coastal areas and marine environments. Large and small organisms live in diverse habitats around the world. Some habitats are characterized by harsh conditions and extreme temperatures - such as the Arctic and desert regions - and support only the hardiest species, while other environments contain copious resources and support large volumes of life.Full Answer >
Biotic factors in the Arctic tundra, as with other ecosystems, include living organisms, such as microorganisms, plants and animals. The biotic factors of the tundra include over 1,500 species of plants, which classify as mosses, lichen and grasses. The hardy group of animals calling the tundra home includes many types of mammals and birds, including polar bears, Arctic foxes, caribou and other iconic species.Full Answer >
