The Effects of Foreign Species Introduction On An Ecosystem The effects of foreign species introduction into an ecosystem are very profound. From small microorganisms to species of large mammals‚ many foreign species introductions occur every day. New implications of their introduction are found just as often. When a foreign species is introduced into an ecosystem‚ often the ecosystem contains no natural predators for the new species. This lack of predators sometimes leads to; in conjunction

M. Velas FUNCTIONS OF LEISURE Relation to Increased Production and Consumption The function of leisure is largely determined by the kind and amount of free time and by the ideas of the age. When spare time consists of short breaks between long periods of sustained labor‚ its function is thought of as recreation – relaxing the worker so that he can work more efficiency after the break. When the goals are efficiency of work‚ increased production‚ more power and more wealth‚ the function of leisure

Biodiversity is the degree of variation of life forms within a given ecosystem‚ biome‚ or an entire planet. Biodiversity is one measure of the health of ecosystems. Life on Earth today consists of many millions of distinct biological species. The United Nations declared the year 2010 as the International Year of Biodiversity. Biodiversity is not consistent across the Earth. In the terrestrial context for example‚ tropical regions are typically rich whereas polar regions support fewer species. Rapid

Impact on the ecosystem Impact on wildlife In a study on the impact of tourist vehicles on the Maasai Mara Reserve in Kenya carried out in 1990‚ it was discovered that for the cheetah‚ it rarely fed during peak driving hours; furthermore‚ it waked off when any vehicle approached closer than 21 meters. When the lion was investigated‚ its peak feeding hours was when the tourists’ vehicles went back to their lodges for launch or to rest; it also fed early during the morning and late during the evening

ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without

Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms that can inhabit these ecosystems. To understand the rates in which certain species’ leaves decay and release the energy stored within them can demonstrate how quickly the energy becomes available to organisms in higher trophic levels. Between plant species the rate of decomposition varies according to leaf structure‚ chemical or physical defence and whether

human use. 3. Ecosystem capital includes the goods and services produced by the species within an ecosystem and the interactions between the biotic and abiotic portions of ecosystems. Ecosystems are expected to produce something of economic value. Natural resources are only those items in an ecosystem that have a monetary value and things with a monetary value are not a resource. Ecosystem capital does not require that a monetary value is known or exists. All that matters with ecosystem capital is that
