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.Know More
Examples of disturbances to ecological balance include bombing during the Vietnam War that destroyed habitat for many species. As part of modern global commerce as of 2014, trees and vegetation are sometimes removed, and those areas in which vegetation is removed and pavement is added tend to expand. As a result, water balance changes, and species of animals and plants must move or change to find alternative habitats and sources of food.
The theory of ecological balance holds that natural systems typically correct themselves when small changes occur. For instance, if a particular species becomes too plentiful, numbers of a predator species may also increase temporarily to bring total numbers back into balance. As of 2014, most ecologists no longer subscribe to the theory of ecological balance and instead feel that natural systems are best described by catastrophe theory, which holds that small changes in one component of a natural system can result in significant and permanent changes to the entire system.Learn more about Earth Science
Bryophytes serve two important functions in an ecological sense: they absorb and release water in certain ecosystems, and they also release acids in other ecosystems. These functions help support certain organisms and other small forms of life in the ecosystems in which they exist, explains McDaniel College. Bryophytes in these ecosystems usually take the form of "moss balls" for their functions.Full Answer >
The ecological species concept defines a species as a group of interrelated organisms that occupy or adapt to a single niche. For example, if a population of birds exploits two different food sources, it represents two distinct species. By contrast, vastly different looking animals may be the same species if they fill the same niche.Full Answer >
According to Universe Today, the duration of a day on Earth is the time it takes for the planet to complete a rotation around its axis. The Earth’s rotation takes 23 hours, 56 minutes and 4.1 seconds.Full Answer >
According to the National Weather Service, a hydrograph is a plot of the water discharge over time. The overall purpose is to chart the flow of a body of water past a particular physical point over a period of time.Full Answer >
