Final answer:
Without the sun, the grass and caterpillar will not survive in the food chain.
Step-by-step explanation:
If the sun is removed from the food chain, photosynthesis will not occur. Photosynthesis is the process by which plants, like grass, convert sunlight into energy. Without the sun, the grass will not be able to produce energy, causing it to die. As a result, the caterpillar, which feeds on the grass, will also die. Therefore, the grass and caterpillar will not survive if the sun is removed from the food chain.
