catastrophes among ecosystems‚ tests need to be performed in essence to keep the ecosystems from being harmed. If‚ for example‚ diatoms and dinoflagellates were to be removed from the food web due to certain chemical factors many organisms (mollusc larvae‚ copepods‚ etc) will not have a food supply therefore resulting in the extinction of many organisms. This leads to disruptions in the ecosystem. The preservation in estuaries is vital for the study of past life and climates‚ as well as present living

When these resources become limited in a shared area‚ organisms are forced to compete with each other for the resources that they need. This competition can occur among individuals belonging to the same

Every day the Earth faces an environmental dilemma that ranges from human factors such as factories which release chemicals into the atmosphere to natural causes such as floods and tornados. It has become hard to pin point which is the most threating to the ecosystem‚ but in recent times the introduction of an invasive species has played a big part in the wide spread changes in the ecosystem. Changes in an ecosystem can affect many species differently‚ if they are unable to adapt to the rapid alteration
