**Figure 4-3: Food Web**This illustration of a food web depicts some of the feeding relationships within a typical marsh ecosystem along the Gulf Coast. One food chain within the food web is highlighted in orange.**Diagram Explanation:**- The diagram includes various organisms, each connected by arrows indicating feeding relationships.- **Highlighted Food Chain (in orange):** Displays a sequence from algae to fish and up to higher predators.- **Key Elements:** - **Algae:** Primary producers at the base of the food web. - **Fish and Small Aquatic Animals:** Serve as primary consumers. - **Larger Predators:** Such as panthers and birds, are depicted as top consumers.- **Color Key:** - Dark Blue: Scavenger - Light Blue: Decomposer - Yellow: Detritivore - Green: Omnivore - Red: Carnivore - Purple: Herbivore - Light Green: Primary ProducerThe food web effectively demonstrates the complexity and interdependency of various species within the marsh ecosystem, illustrating the flow of energy through different trophic levels. **Critical Thinking Exercise**3. **Construct an Explanation**: Suppose there was a sudden decrease in the number of crayfish in the food web shown in Figure 4-3. Construct an explanation to explain how this change may affect the food web.[Notebook Icon]
