In ecology‚ predation describes a biological interactions[->0] where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Predators may or may not kill their prey prior to feeding[->1] on them‚ but the act of predation always results in the death of its prey and the eventual absorption of the prey’s tissue through consumption.[2] Other categories of consumption[->2] are herbivory[->3] (eating parts of plants) and detritivory[->4]‚ the consumption of dead organic

Not only is it our job to protect Canada’s wild spaces and Canada’s places of historical and cultural interest‚ it is a necessity that will benefit the natural environment greatly. The natural resource industry and the creation of jobs need balance‚ the preservation of wildlife needs to be enforced‚ and the people need to become immersed in the natural environment and all it has to offer. Three policies that would benefit the country as a whole include; the prevention of overexploitation of natural

Environmental science is the study of how the natural world works‚ how our environment affects us‚ and how we affect our environment. It includes the disciplines of ecology‚ earth sciences‚ economics‚ and political science. 4. Science is described as a systematic process for learning about the world and testing our understanding of it‚ it is also used to refer to the accumulated body of knowledge that arises from

food source. It is also sometimes applied to the relationship between the Earth’s ecosystem‚ the composition of the atmosphere‚ and the world’s weather. The Gaia hypothesis is a balance of nature-based theory that suggests that the Earth and its ecology may act as co-ordinated systems in order to maintain the balance of nature. The theory that nature is permanently in balance has been largely discredited‚ as it has been found that chaotic changes in population levels are common‚ but nevertheless

However‚ in the present day‚ forests are threatened by deforestation which occurs in many countries‚ but mostly in Europe‚ North Africa‚ and the Middle East (Thoreau‚ 2010).

level is central to ecology. Energy flows between trophic levels. The input of energy to a higher trophic level population from a lower trophic level population can be controlled by the amount of energy available in the lower level‚ or by the amount of energy the higher trophic level is able to consume. Or we take into consideration such factors as the “natural" growth rate and the "carrying capacity" of the environment in the dynamics of a single population. Mathematical ecology requires the study

Wildlife conservation is the practice of protecting endangered plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife andwilderness lands to humans.[1] Many nations have government agencies dedicated to wildlife conservation‚ which help to implement policies designed to protect wildlife. Numerous independent nonprofit organizations also promote various
