Factors causing changes to the ecosystem
All species within an ecosystem will experience some kind of limiting factors to prevent continuous and exponential growth (even humans) environmental changes (ie drought, famine, human destruction) results in decreased rates of physiological processes, lowering the potential for survival, growth, or reproduction. Change in an organism's environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species for example, if a species of animal is mostly limited to eating one kind of leaf, and a change occurs: a fungus attacks and kills most of that kind of plant, the animal has to evolve either to fight . This approach, in addition to the use of a rigorous and ‘environmentally explicit’ framework that considers all levels of environmental change will undoubtedly allow researchers to examine the root causes of existing health conditions and potential future diseases for wildlife in the context of a rapidly changing environment. Here, we present current knowledge on the effects of climate change on biotic interactions and ecosystem services supply, and summarize the papers included in this volume we discuss how resilient ecosystems are in the face of the multiple components that characterize climate change, and suggest which current ecological theories may be used as . Changes in one of the physical factors of the environment may cause the decline and extinction likewise the fossil record indicates that some extinctions are caused by migration of a competitor dramatic declines in human population happen periodically in response to an infectious disease.

Ecosystem is the environment where biotic/ living things live and interact with nonliving things/abiotic factors such as coral reef, forest, grassland, farm etc in 1935, the word “ecosystem” was invented by a british ecologist sir arthur george tansley, who depicted natural system in . Causes of environmental change how does societal development affect environment in a positive way _ it improves quality of life _ it addresses basic human needs as ‘higher order’ needs in a negative way _ it increases the demand for resources and goods (increases consumerism) _ it leads to unsustainable land use practices _ it increases and concentrates generation of pollution and waste . Climate change - a threat to aquatic ecosystems climate change – overview there are many factors that can cause a warming of our climate for example, more . The cause erosion, and more as you can imagine, a desert, or forest is a lot different with biotic factors living in it they feed off of plants, their dead carcuses decompos e in the ground .
The living environment describes all the living things that interact with an organism, either directly or indirectly the living (or biotic) factors influence the life of an organism and includes factors such as the availability of food, the presence of predators or competitors and disease organisms . Cancer-causing substances in the environment cancer is caused by changes to certain genes that alter the way our cells function does not mean that the . Climate change evidence & causes the magnitude and timing of these changes will depend on many factors, and slowdowns and accelerations in warming lasting a decade.
Biodiversity describes the variety of species that make up an ecosystem an ecosystem is the combination of the living and nonliving things in a location. In addition, habitat fragmentation, the division of ecosystems and populations of species into smaller, isolated, sometimes unsustainable parcels, often causes loss of biodiversity by increasing vulnerability of some populations to disease and other stressors, leaving habitats too small for some species to survive. Literature review has identified a set of factors that are able to trigger cultural changes these factors causing cultural change have been found as leadership change, technological developments, mergers and acquisitions and others discussions of each of these factors in greater details are . Natural or human-induced factors that directly or indirectly cause a change in an ecosystem are referred to as drivers a direct driver , such as habitat change , explicitly influences ecosystem processes .

Generally, changes in physical environment force migration of people in large numbers and this brings major changes in social life and cultural values also migration itself encourages change, for it brings a group into a new environment, subject to its new social contacts, and confronts it with new problems.
