Ecosystem Paper Select an ecosystem in your area (forest, lake, desert, grassland). Write a 525- to 700-word paper explaining the following: 1) Describe the structure of your ecosystem including important abiotic features and dominant plant and animal species. 2) Explain some functions/processes of your ecosystem including one nutrient cycle and one food chain. 3) Give two examples of species interactions (predation, competition, mutualism, etc.) that occur in your ecosystem. 4) Identify an invasive species in your ecosystem. Explain its effects on the ecosystem and efforts to control or eradicate it. Include two outside references. Format your paper consistent with APA guidelines.

The ecosystem I have chosen to explore is the freshwater lake ecosystem located near my community. This type of ecosystem is characterized by a complex interplay of abiotic and biotic components that sustain diverse forms of life. Understanding its structure, functions, species interactions, and challenges such as invasive species provides insight into the ecological dynamics at play.

Structure of the Lake Ecosystem

The lake ecosystem comprises several key abiotic features, including water chemistry, temperature, light penetration, and nutrient availability. The water’s temperature varies with seasonal changes and depth, influencing the distribution of organisms within the lake. Light penetration is typically limited to the upper layers, affecting photosynthesis rates. Nutrients such as nitrogen and phosphorus are essential for primary productivity but can become problematic when in excess, leading to phenomena like algal blooms.

Dominant plant species include phytoplankton, submerged aquatic plants like pondweed, and emergent vegetation such as cattails near the shoreline. These plants provide oxygen, habitat, and food for many aquatic animals. Animal species include fish such as bass and bluegill, amphibians like frogs, invertebrates such as zooplankton, and bird species like ducks and herons. Together, these organisms form a dynamic and interconnected community.

Functions and Processes of the Lake Ecosystem

One vital process in this ecosystem is the nitrogen cycle. Nitrogen enters the ecosystem primarily through rainfall and decomposition of organic matter. It is converted by bacteria in the water and sediment into forms usable by plants, such as ammonium and nitrate. These nutrients support the growth of phytoplankton, which forms the base of the food web. The nitrogen cycle is essential in maintaining ecosystem productivity and preventing nutrient imbalances.

Regarding food chains, a simplified example in this lake involves phytoplankton as primary producers, tiny zooplankton as primary consumers, small fish like minnows feeding on zooplankton, and larger predatory fish such as bass preying on small fish. This chain illustrates the transfer of energy from the sun through photosynthesis to various consumers, maintaining the food web's stability.

Species Interactions in the Lake Ecosystem

A key interaction is predation, exemplified by larger fish species preying on smaller fish and invertebrates. This interaction helps regulate populations and maintain balance within the community. Another example is mutualism between certain aquatic plants and nitrogen-fixing bacteria that colonize their roots, enhancing nutrient availability for the plants and benefiting bacteria through a habitat; this symbiosis boosts primary productivity in the ecosystem.

Invasive Species in the Lake Ecosystem

An invasive species impacting this lake is the common carp (Cyprinus carpio). Originally introduced for sport fishing, carp have proliferated and disrupted aquatic habitats through their bottom-feeding behavior, which increases turbidity and uproots aquatic plants. These activities reduce water quality, displace native species, and alter the pre-existing food web dynamics. Efforts to control carp populations include physical removal, barriers to restrict movement, and environmental management practices designed to favor native species’ recovery (Keller et al., 2014). Continued research and management are essential to mitigate the adverse effects of this invasive species and restore the ecological balance of the lake system.

Conclusion

The lake ecosystem exemplifies a delicate balance of abiotic and biotic elements functioning collectively to sustain biodiversity. Understanding the structure, nutrient cycles, species interactions, and the challenges posed by invasive species is vital for developing effective conservation strategies. Protecting such ecosystems ensures the preservation of their ecological services and the biodiversity they support.
