APAKAH MAKSUD PHOTIC dalam CORSICA?
Zon fotik
Zon photik, zon euphotic, atau zon cahaya matahari adalah kedalaman air di dalam tasik atau lautan yang terdedah kepada cahaya matahari yang mencukupi untuk terjadi fotosintesis. Ia memanjang dari permukaan ke kedalaman di mana intensiti cahaya jatuh ke satu peratus daripada itu di permukaan, yang dipanggil kedalaman euphotic. Oleh itu, ketebalannya bergantung kepada tahap pengecilan cahaya dalam lajur air. Kedalaman euphotic yang tipikal berbeza dari hanya beberapa sentimeter di tasik eutropik yang sangat keruh, hingga kira-kira 200 meter di lautan terbuka. Ia juga berbeza-beza dengan perubahan bermusim dalam kekeruhan. Oleh kerana zon photik adalah di mana hampir semua produktiviti utama berlaku, kedalaman zon photik umumnya berkadar dengan tahap produktiviti utama yang berlaku di kawasan lautan itu. Sekitar 90% daripada semua kehidupan marin tinggal di zon photik. Sebilangan kecil pengeluaran utama dihasilkan jauh di dalam zon abyssal di sekitar lubang-lubang hidroterma yang wujud di sepanjang rabung tengah laut. Zon yang meluas dari pangkal zon euphotic hingga kira-kira 200 meter kadang-kadang dipanggil zon disphotic.
