What are the effects of prolonged shade on algae growth in rattan sculptures?

Prolonged shade significantly inhibits algae growth on rattan sculptures by limiting photosynthesis, the primary energy source for algae. Without sufficient light, chlorophyll production slows, reducing metabolic activity and biomass accumulation. Shaded environments also decrease moisture retention, further stunting algal colonization. Over time, this leads to sparse or patchy growth patterns, altering the sculpture's aesthetic and ecological balance. Understanding these effects helps in preserving rattan artworks and managing their exposure to natural light.
