Provide examples of how disruptions to ecosystems can affect

Provide examples of how disruptions to ecosystems can affect the dynamics of the

ecosystems. Utilize the following examples.

-Invasive and eruptive species

-Human impact

-Hurricanes, floods, earthquakes, volcanoes, fires

-Water limitation

-Salination

Solution

Invasive species are non native species for a particular environment and they tend to spread enormously and thus cause harm to the native species and that environment.

Eruptive species are species which vary in their population ranging from endemic to epidemic. Thus this way these species are capable enough to cause disruption in the environment.

Humans have huge impact on the ecosystem as human is dependent on ecosystem so much and so that in that process only it disrupts the environment. Cutting of trees, causing anthropogenic pollution, global warming etc., are som of the examples.

Hurricanes, floods, earthquakes , volcanoes, fires etc are known to cause huge disruption in the ecosystem by disturbing the balance either temporarily or permanently. They do this by disturbing the fauna and flora of that particular ecosystem and also causing devastation in that area. Vocanoes etc are a source of acid rain and they enhance global warming too.

Water limitation is an another important factor as when water intensive crops are grown they cause enormous harm to ecosystem.

Enhancement in salinity level of river water cause death of salt sensitive organisms and this in turn cause disruption of food chain and food web.
