The levels of ecological organization are the biosphere, biome, ecosystem, community, population and individual. Ecological organization helps people understand the structure and function of entire groups of microbes, plants and animals individually and as a whole.Know More
The Earth is a biosphere. It includes all living organisms, both plants and animals, as well as every biome on Earth. Biomes are specific regions that share like ecosystems. There are desert, forest, tundra, grassland and aquatic biomes on Earth. Each of these major biomes is divided into distinct types. For instance, the forest biome is divided into temperate, tropical and boreal forests.
An ecosystem includes a specific community of living organisms, but also includes other abiotic factors, such as rocks, water, air and temperature. A community consists of all organisms in an area at a given time. Communities are normally biologically diverse.
A population is a given species in an area at a given time. Populations include different genetic makeup of the same species. For instance, the human population includes various ethnicities. Lastly, individual can be defined as any living species or organism. Individuals do not breed with individuals from other groups. Animals are very definite concerning cross-breeding, while some plants do cross-breed with other plants.Learn more about Environmental Science
The gray wolf, the largest canine species in the world, is a keystone predator in northern areas that eats big, hoofed animals such as moose, elk, bison, deer and caribou. They live in the northern hemisphere of America, Europe and Asia. The gray wolf once roamed over two-thirds of the United States until intense hunting threatened the species to extremely low levels in the 1930s.Full Answer >
Protists serve numerous purposes in the ecosystem including producing between 70 and 80 percent of the world's oxygen, being a main food source for aquatic animals and a major decomposing agent of dead material. Protists can measure up to 300 feet long, as in the case of the giant kelp of the kelp forests in the Pacific Ocean.Full Answer >
The three ecological pyramids are a Pyramid of Numbers, a Pyramid of Biomass and a Pyramid of Energy Flow. All three ecological pyramids illustrate the reduction in energy when moving through each feeding level in an ecosystem.Full Answer >
The stages of ecological succession are primary succession, when opportunistic species move into a mostly lifeless environment, and secondary succession, when new species displace the primary succession species once the latter has modified the environment. In some cases, secondary succession proceeds to a climax community.Full Answer >
