To answer the question, we need to understand the different options provided and determine which organisms produce food in an ecosystem without photosynthesis.

1. Photo-autotrophs: These organisms are capable of producing food through photosynthesis, so they do not fit the criteria of producing food without photosynthesis.

2. Chemo-autotrophs: These organisms obtain energy by breaking down inorganic compounds, such as sulfur or ammonia, and converting them into organic molecules. They can produce food without relying on photosynthesis. Therefore, chemo-autotrophs are a possible answer.

3. Blue green algae: Blue green algae, also known as cyanobacteria, are photo-autotrophs. They use photosynthesis to produce food, so they do not fit the criteria of producing food without photosynthesis.

4. Earthworms: Earthworms are not capable of producing food through photosynthesis. However, they are not autotrophs, meaning they do not produce their own food. Instead, they are heterotrophs and obtain their food by consuming organic matter in the soil. Therefore, earthworms do not fit the criteria of producing food without photosynthesis.

Based on the options provided, the correct answer is chemo-autotrophs.
