Los océanos: zona fótica

The video explores the epipelagic zone of the ocean, highlighting the abundance of life forms beneath the surface. It explains how microscopic organisms like plankton and algae perform photosynthesis, forming the base of the food chain. Various predators, including fish and birds, are attracted to this zone. The video also discusses the role of seamounts as relatively safe areas for young fish to grow and mate, despite the presence of predators. Finally, it hints at the vastly different world that exists a few hundred meters below the epipelagic zone.

What is the primary function of plankton and algae in the epipelagic zone?

• They decompose organic matter.

• They act as predators in the food chain.

• They convert solar energy through photosynthesis.

• They provide shelter for fish.

Which of the following is NOT a predator found in the epipelagic zone?

• Tuna

• Marlin

• Dolphins

• Seahorses

What role do floating debris and algae play in the open ocean?

• They increase the water temperature.

• They attract more predators.

• They offer some shelter from predators.

• They provide a food source for large predators.

Why are seamounts considered relatively safe for young fish?

• They have abundant food resources.

• They are located in shallow waters.

• They provide a place to grow and mate.

• They are free from any predators.

Which predator is known to patrol the areas around seamounts?

• Great white sharks

• Barracudas

• Hammerhead sharks
