Answer: (C)

Verified step by step guidance

1. Understand the concept of ecological succession: It is the process by which ecosystems change and develop over time, starting with pioneer species that colonize barren or disturbed environments.
2. Define pioneer species: These are the first organisms to colonize an area during the early stages of ecological succession. They are typically hardy and able to survive in harsh conditions with minimal resources.
3. Analyze the options provided: Fungus, shrubs, grass, and trees. Consider which of these organisms fits the definition of a pioneer species based on their ability to colonize barren environments.
4. Recognize that grass is often considered a pioneer species because it can grow in nutrient-poor soils, stabilize the soil, and create conditions suitable for other species to follow in the succession process.
5. Conclude that grass is the correct answer, as it aligns with the characteristics of a pioneer species in ecological succession.
