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.Know More
A Pyramid of Numbers counts all of the organisms at each specific feeding level. This can be difficult in some ecosystems, as it is not always possible to count how many of each species is present.
A Pyramid of Biomass collects the organisms from each feeding level, then dries and weighs them. The dried weight shows the amount of organic matter of the organisms.
A Pyramid of Energy Flow measures the caloric value of the organisms at every feeding level.Learn more about Environmental Science
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 >
Ecological balance is important for the continued survival and existence of organisms as well as the stability of the environment. The natural balance in the ecosystem, which must be maintained, may be disturbed as a result of natural hazards, the unexpected death of a particular species, man-made causes or the introduction of new species to the ecosystem.Full Answer >
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.Full Answer >
Ecosystems that have biodiversity are very productive, recycling nutrients easily and quickly. Such ecosystems are healthy, self-sufficient and better able to overcome disasters. Biodiversity acts as a system of checks and balances; if one part of an ecosystem weakens for awhile, stronger parts help it survive.Full Answer >
