Answer: (C)

Verified step by step guidance

1. Understand the concept of biodiversity: Biodiversity refers to the variety of life in an ecosystem, including different species of plants, animals, and microorganisms. Ecosystems with higher biodiversity are generally more resilient to disturbances, such as diseases.
2. Analyze the role of grasses in the ecosystem: Grasses are primary producers, meaning they convert sunlight into energy through photosynthesis. If a disease kills the grasses, the ecosystem's energy flow and food web could be disrupted.
3. Evaluate the options: Consider how each type of ecosystem would respond to the loss of grasses. Ecosystems with no plant species or only animal species would lack primary producers, leading to a collapse of the food web. An ecosystem with only one plant species would be vulnerable to diseases targeting that species.
4. Consider the benefits of plant diversity: An ecosystem with many different plant species would be more likely to survive because other plants could compensate for the loss of grasses, maintaining energy flow and supporting the food web.
5. Conclude that biodiversity enhances resilience: Ecosystems with many different plant species are better equipped to adapt to changes and recover from disturbances, making them more likely to survive in the event of a disease killing the grasses.
