SCIE211 PHASE 5: IDENTIFYING ENVIRONMENTAL HAZARDS ✓ Solved

To find out why there is increases and decreases in the invasive species population? To investigate the implications associated with alterations to the ecosystem as a whole?

Invasive species in an ecosystem are the species that consumes others making the extinct. From the principle of interdependence and food chain, some species provide food to others and therefore their continued consumption decreases their number while there is increase in number of the organisms that consume them (Mc Cann, 2012). Due to their reduction in number, the organisms that consume them also reduce in number due to starvation.

Once the consumers have reduced in number, the producers on the other hand increases in number (Mc Cann, 2012).

The consumers should first increase in number as the producers decrease and later decrease in number as the producers increase in number.

A sample of the producers and consumers was observed in an enclosed ecosystem in a water body. The number of each was counted, and the data was calculated and then recorded. The sampling was done after some period of duration and the data recorded in the table of the results (Mc Cann, 2012).

From the data achieved in the experiment, it can be verified that increase in number of producers would result in increase in number of consumers as the availability of food would increase the rate of reproduction in the organisms as well as better immune systems to resist diseases. Increase in number of consumers in turn causes population crisis as there is much competition for the inadequately available producers hence leads to starvation and consequently death, which consequently increases the number of producers as there are less consumers as shown in the data (Mc Cann, 2012).

The dynamics of environmental hazards significantly impact ecosystems and highlight the interdependence of species within specific habitats. In deeper analysis, invasive species stand out as pivotal drivers in the fluctuations observed in ecosystem populations. The inquiry into why invasive species populations experience increases and decreases is crucial for environmental science and management. This paper focuses on the effects of invasive species on ecosystem balance, utilizing a structured approach to understanding the hypothesis of predator-prey interactions and the implications for biodiversity.

Understanding the behavior and outcomes of consumer (predator) and producer (prey) relationships is essential. The basis of food webs and interdependent relationships implies that when invasive species enter an ecosystem, they may disrupt existing consumer-producer dynamics. Non-native species often face fewer natural predators, enabling them to proliferate rapidly. For instance, the introduction of Zebra mussels in North American waters has disrupted local ecosystems by outcompeting native species for food resources (Gordon, 2018).

The hypothesis outlined indicates that the population trends among consumers and producers are closely linked. As invasive species, which often act as consumers, increase, they may initially lead to a decline in native producers due to increased competition for resources. Over time, however, this can create an ecological imbalance leading to further repercussions. When the invasive species deplete the resources, the population of consumers can decline, resulting in a resurgence of producer populations (Mc Cann, 2012).

The method of investigating these population dynamics involved observational studies within a controlled aquatic environment. By measuring different species' populations over time, including Zebra and Quagga mussels (density/m²), phytoplankton, zooplankton, and other organisms present in the same habitat, data were collected for analysis. This longitudinal study approach allows for the visualization of trends and the relationships between these populations. Researchers have documented that increases in phytoplankton can facilitate increased consumer populations, as they provide a more abundant food source following the successful establishment of these producers (Mills et al., 2016).

Another important aspect to consider is the role of various native fish species, such as Lake Trout, which can also exhibit population fluctuations based on the availability of their prey. The fluctuating biomasses of Cladophora—a type of green algae—exemplify the interlinked relationships where both producers and consumers must adapt to changes brought about by invasive species (Karatayev et al., 2015). Therefore, it is evident there is a reciprocal relationship in the ecological community, where changes in one group directly affect another.

In conclusion, dealing with invasive species necessitates strategic management approaches aimed at maintaining the balance within ecosystems. Recognizing the outcomes presented by invasive species proliferation illuminates the vital importance of preserving biodiversity for the health of ecosystems at large. By continually researching population dynamics, environmental scientists and policymakers can develop informative frameworks and proactive measures to mitigate detrimental impacts on native species—bridging gaps between ecological knowledge and practical conservation strategies (Simberloff, 2013).

Invasive species not only impact local fauna and flora but also pose significant challenges for biodiversity. The crisis resulting from their introduction can severely alter the structure of ecosystems, making proactive intervention and management crucial for ecological stability. Continued investigation and adjustments in policies are essential to address the shifting paradigms of ecological interactions driven by invasive species.
