Effects on the Environment
An ecosystem is a society of living organism together with the non-living components of the environment interacting with a system. Non-living organisms are things like water, air and mineral soils. In studying the ecosystems, there are several techniques to study the ecosystem which include; experiments and modeling.
Collecting field data is the initial step to understand the ecosystem, although some issues cannot be solved by field surveys. In such cases, ecologists employ scheming practical with control management to assess the hypotheses on how the ecosystem operates.
Advantage: Field experiment is likely to display real life since of its natural setting.
Advantage: Demand characteristics that affect the results are minimal, as participants are unlikely to realize they are being studied.
Disadvantage: there is minimal control on unrelated variables that may be bias to the results.
Disadvantage: They may be more expensive and time consuming than lab experiments.
Modeling is another important tool used by ecologists in studying the ecosystems; a model can acquire many forms but represent in particular hypothesis on the technicalities of an ecosystem. This can contribute to predict expansion rate of disease-carrying mosquitoes can be used in the medical field to inform doctors of risk areas to watch out for new diseases like malaria that they might not have occurred earlier.
Advantage:  Models do help ecologists to predict on things as various as how changes to climate impact the range of mosquitoes species carrying diseases.
Advantage:  The best thing in modeling is that it can let researchers experiment a variety of scenarios that would be very expensive and difficult to do the experiments.
Disadvantage: The need of reliance on functional mechanisms reduces their demand to the functionally orientated ecologist.
Disadvantage: Disappearance from the easy assumptions of stationary chains while practically possible makes unequal degrees of difficulty in computation and analysis.
