Analisis Densitas Zooxanthellae Pada Karang Acropora Sp Di Pulau Pagang, Kabu…
Coral reefs play a crucial role in maintaining the stability of marine ecosystems. Healthy coral growth is often indicated by the presence of symbiotic zooxanthellae within the coral tissue. The density of zooxanthellae varies and is influenced by several factors. Depth affects these limiting factors—such as light intensity, temperature, and ocean acidity—which in turn impacts zooxanthellae…
