Your Task For This Project Is To Construct An Illustrated Fo ✓ Solved

Your task for this project is to construct an illustrated food

Part 1: Your task for this project is to construct an illustrated food web to diagram trophic interactions in the Everglades ecosystem. The food web must be an original creation; you cannot submit a food web that you find online. You must use a minimum of 8 species that are found in the Everglades. You must indicate, using arrows or lines, the flow of energy between the species in your diagram.

Part 2: Answer the following questions about the food web you constructed. Answers should be provided on a separate attachment in the assignment dropbox.

  1. List the producer(s) in your food web.
  2. List the herbivores in your food web.
  3. Are there any organisms in your food web that are omnivores? On which trophic levels are they feeding?
  4. List the carnivores in your food web.
  5. Identify and list a food chain within your food web that depicts at least three trophic levels. What organism in your selected food chain is a secondary consumer?
  6. Are there any nonnative species in your food web? Briefly describe how they are altering this food web in the Everglades ecosystem.
  7. Choose a primary consumer in your food web. If its population suddenly started to decline, what density-dependent (biotic) factors could be causing it?
  8. Choose a secondary consumer in your food web. If its population suddenly started to increase, what density-dependent (biotic) factors could be causing it?
  9. Are there any keystone species in your food web? If a keystone species were removed from your food web, how would its loss impact the other organisms?
  10. Are there any endangered or threatened species in your food web? If the species goes extinct, how would its loss impact the other organisms?

Paper For Above Instructions

The Everglades ecosystem, located in southern Florida, is a unique and diverse environment that hosts a plethora of species, forming a complex web of life characterized by intricate trophic interactions. In constructing an illustrated food web, we will analyze various species that inhabit this region, demonstrating their roles within this ecosystem.

Illustrated Food Web Construction

The illustrated food web includes at least eight species, comprising producers, herbivores, omnivores, and carnivores. In the Everglades, a typical food web might consist of the following species:

  • Producers: Sawgrass (Cladium jamaicense) and aquatic plants like Water Lily.
  • Herbivores: American Alligator (Alligator mississippiensis) cubs, marsh rabbits (Sylvilagus palustris), and various insects.
  • Omnivores: Raccoons (Procyon lotor) and certain birds such as the Great Egret (Ardea alba), which feed on fish and vegetation.
  • Carnivores: Wading birds, such as the Roseate Spoonbill (Platalea ajaja), and Florida Panthers (Puma concolor coryi).

Trophic Levels and Energy Flow

In the food web constructed, energy flow is indicated by arrows connecting the species. For example, it might show energy flowing from the producers (such as sawgrass) to herbivores (like marsh rabbits), and then to secondary consumers (like raccoons). One possible food chain identified within this web could be:

Producers (Sawgrass) → Primary Consumers (Marsh Rabbits) → Secondary Consumers (Raccoons).

In this case, the raccoons are the secondary consumers, as they prey upon the marsh rabbits.

Nonnative Species Impact

Within the Everglades ecosystem, the presence of nonnative species such as the Burmese Python (Python bivittatus) can have significant repercussions. This large constrictor snake preys on small mammals and birds, disrupting the natural balance and diminishing the populations of native species, thus altering the food web dynamics.

Population Dynamics and Density-Dependent Factors

Considering a primary consumer, such as the marsh rabbit, if its population were to decline, potential density-dependent factors could include increased predation from carnivores like alligators, competition for food among herbivores, or disease outbreaks. On the other hand, if a secondary consumer like the raccoon experiences a sudden population increase, it might be due to an abundance of food sources, such as increased populations of its prey or decreased competition from other omnivores.

Keystone Species and Their Importance

In this food web, the Florida Panther serves as a keystone species. Its presence helps regulate the populations of herbivores. If the panther were removed from the ecosystem, it could lead to an overpopulation of primary consumers, thereby resulting in overgrazing and consequent damage to vegetation, ultimately collapsing the food web structure.

Endangered Species and Ecosystem Impact

The Everglades is home to several endangered species, such as the American Crocodile (Crocodylus acutus). If this species were to go extinct, the implications would be severe. The crocodile plays a critical role in controlling fish populations, and its absence could lead to overpopulation of these species, which may further destabilize the food web. The loss of any species within this interconnected system can precipitate cascading effects throughout the entire ecosystem.

Conclusion

The Everglades ecosystem's food web represents a delicate balance of various trophic interactions. Understanding these interactions highlights the complexities of energy flow and species reliance. As we observe the dynamics between native and nonnative species and the roles of keystone and endangered species, it becomes crucial to recognize the importance of maintaining this ecological balance for the health of the environment.
