The correct Answer is:
To determine which group is an essential component for the survival of an ecosystem, we need to analyze the roles of different groups within the ecosystem. Here’s a step-by-step solution: ### Step 1: Identify the Groups The options provided are: 1. Producers 2. Producers and Herbivores 3. Producers and Decomposers 4. Detritivores ### Step 2: Understand the Role of Each Group - **Producers**: These are typically plants and photosynthetic organisms that convert solar energy into chemical energy through photosynthesis. They form the base of the food chain. - **Herbivores**: These are primary consumers that feed on producers. They play a crucial role in transferring energy from producers to higher trophic levels. - **Decomposers**: These organisms, including bacteria and fungi, break down dead organic matter and recycle nutrients back into the ecosystem, making them available for producers again. - **Detritivores**: These organisms feed on dead organic matter and play a role similar to decomposers in nutrient cycling. ### Step 3: Analyze the Options - **Producers alone**: While they are essential for energy capture, they cannot sustain an ecosystem alone without consumers and decomposers. - **Producers and Herbivores**: This combination is crucial for energy transfer, but it still lacks the nutrient recycling aspect. - **Producers and Decomposers**: This combination is vital as it includes energy capture (producers) and nutrient recycling (decomposers), which are both essential for ecosystem sustainability. - **Detritivores**: While they contribute to nutrient cycling, they are not as fundamental as the combination of producers and decomposers. ### Step 4: Conclusion The most essential group for the survival of an ecosystem is **Producers and Decomposers**. They work together to ensure energy flow and nutrient cycling, which are critical for maintaining ecosystem balance. ### Final Answer **Producers and Decomposers** are essential components for the survival of an ecosystem. ---
