Here's a picture of a Phyllora and a Vinecer resting next to a compost pile. They are performing photosynthesis while they rest.
Phylloras build compost piles to make fertilizer for their communities. They build simple tools to help them manage their compost. Vinecers also help with the compost, as they also use it. Phylloras mix the compost into the soil in their homes. Vinecers mix it into their drinking water.
