Here are the answers to the questions you provided:
1. **According to the food web, which organism is a producer in the Mangrove Swamp?**
- **Phytoplankton** (Producers are organisms that produce their own food, typically through photosynthesis.)
2. **How did this change most likely affect populations of insects living among the grasslands?**
- **They decreased because the resources they needed were not available.** (Drought conditions would reduce food sources such as grass.)
3. **Which things from the image make up the pond community?**
- **Grasses, cattail reeds, fish, ducks, turtles, frogs, crayfish, and insects.** (These are all living organisms that contribute to a community.)
4. **How do consumers get energy to function?**
- **Consumers obtain all of their energy by eating other organisms.** (Consumers cannot produce their own food; they need to consume other living beings.)
5. **How are auditory and visual communication different?**
- **Only auditory communication uses sound to send a message.** (Auditory is based on sounds, while visual relies on sight.)
6. **Which statement is most likely true of the kinds of animals represented by animal A and animal B in the graph?**
- **A is a predator, whereas B is prey.** (Typically, predator populations increase as prey populations decrease.)
7. **Which of the following statements best describes the relationship between ecosystems and biomes?**

8. **Which of the following describes the relationship between a hermit crab and the mollusk that previously lived in the hermit crab’s shell?**
- **Commensalism.** (Hermit crabs benefit from the shells of mollusks without harming them, although it is not mutual.)
9. **What causes competition to occur in an environment?**
- **Organisms struggle for a limited resource.**
10. **What is the primary role of decomposers in an ecosystem?**
- **To recycle energy and materials from dead producers and consumers.**
11. **Which of the following best describes what the food chain represents?**
- **The path of energy transfer from producers to consumers.**
12. **Which of the following is a resource for which two trees growing next to each other in a forest would most likely compete?**
- **Nutrients in the soil.** (Both trees require nutrients for growth.)
13. **What is a limiting factor?**
- A limiting factor is any biotic or abiotic resource that restricts the growth, abundance, or distribution of organisms in an ecosystem.
14. **How can limiting factors limit the size of a population?**
- Limiting factors can restrict the number of individuals that can be supported in an environment, influencing resource availability, reproductive rates, or survival rates.
15. **Describe what an energy pyramid represents.**
- An energy pyramid represents the flow of energy through different trophic levels in an ecosystem, showing how energy decreases as you move up from producers to various levels of consumers.
16. **What would be the order of these organisms in an energy pyramid, from beginning to end?**
- **Grass plant (producer) -> Grasshopper (primary consumer) -> Shrew (secondary consumer) -> Owl (tertiary consumer).**
17. **Which organism is the producer? Explain.**
- **The grass plant is the producer, as it produces its own food through photosynthesis.**
18. **Which organism is a tertiary consumer? Explain.**
- **The owl is the tertiary consumer, as it feeds on secondary consumers (like the shrew) in the food web.**
19. **Give an example of a biotic and an abiotic limiting factor in a forest ecosystem.**
- **Biotic factor:** Competition for food (for example, between animals).
- **Abiotic factor:** Availability of water or sunlight.
20. **Which of the following describes the most likely reason that a group of predators of the same species would cooperate?**
- **To kill a larger animal for food.** (Cooperation can enhance hunting success for larger prey.)
