Applications Of Biotechnology

Step 1: Aquatic ecosystems are divided into different zones based on depth and distance from the shore.
Step 2: The littoral zone is the shallow region near the shore.
Step 3: This zone is periodically exposed to air due to tides or water level fluctuations and is also submerged under water.
Step 4: It supports rooted plants and a high diversity of organisms.

Step 1: Recall the origin of Green Fluorescent Protein (GFP). Green Fluorescent Protein (GFP) was first discovered in the jellyfish \textit{Aequorea victoria}.
Step 2: Understand its biological role. In jellyfish, GFP:
absorbs blue light,
emits green fluorescence,
contributes to bioluminescence.
Step 3: Eliminate incorrect options.
Primate: GFP is not naturally found in primates.
Cuttlefish: Known for camouflage, not GFP.
Shark: Does not produce GFP.
Hence, the correct answer is
