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, using sunlight as their source of energy. Therefore, they do not fit the criteria of producing food without photosynthesis.

2. Chemo-autotrophs: These organisms are able to produce food through a process called chemosynthesis. They obtain energy by breaking down inorganic compounds, such as hydrogen sulfide or ammonia, instead of relying on sunlight. Chemo-autotrophs can be found in environments such as deep-sea hydrothermal vents or sulfur-rich caves.

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

4. Earthworms: Earthworms are not capable of producing food through photosynthesis or chemosynthesis. They are heterotrophs, which means they obtain their food by consuming organic matter in the soil. Earthworms play an important role in the decomposition process and nutrient cycling in ecosystems.

Based on the options provided, the organisms that produce food in an ecosystem without photosynthesis are chemo-autotrophs.
