What part of the city has a similar job to chloroplast?

In a city, the part that resembles the role of chloroplasts is the parks and green spaces. Just as chloroplasts convert sunlight into energy for plants through photosynthesis, parks and green areas absorb sunlight and provide oxygen while also serving as vital ecosystems. They contribute to the city's overall health by improving air quality and providing a habitat for wildlife, much like how chloroplasts support plant life.
