Ecological balance is a stable state between all plants and animals in an ecosystem, and destabilization of the stable state is ecological imbalance. When plants and animals share a particular habitat, balance must be maintained for the benefit of all organisms.
One of the most important challenges facing humanity is the disturbance in this ecological balance due to human activity. The rising human population and the consequent encroachment of humans into forests and other ecosystems are the chief causes of ecological imbalance.
Ecological imbalance can cause sweeping changes in the world. Eventually, all organisms are affected by ecological imbalance. Many species may be wiped out, and others may suffer irreparable damage due to an imbalance in the ecology.Learn More
An ecological pyramid is a graphical model that illustrates the flow of energy through different forms of life in an ecosystem. The bottom level illustrates species which act as producers, harnessing energy from abiotic sources. Each subsequent level illustrates a level of consumer, each of which receives energy by consuming the group below it.Full Answer >
Ecological balance is a theory stipulating that natural conditions, including numbers of various animal and plant species, remain stable on their own through variations over time. The theory, also known as balance of nature, also holds that natural equilibrium can be changed significantly by new species entering an ecosystem, the disappearance of some species, man-made changes to the environment or natural disasters.Full Answer >
Ecological assessment refers to the monitoring of ecological resources to determine current and changing conditions. It is a process of evaluating the likelihood that the environment may have been affected as a result of being exposed to environmental stressors, including chemicals, disease, climate change and land change.Full Answer >
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 >
