The Blooming of Plankton

Introduction

• Phenomenon occurs when the Sun is strong and currents rise to the surface.
• Visible from space; described as a blooming or explosion of life.

What is Plankton?

• Defined as floating life that cannot move independently and drifts with water.
• Mainly occurs in the upper layers of the ocean, particularly within the first 100 meters of depth where sunlight penetrates.

The Role of the Sun

• Sunlight provides the energy necessary for plankton blooming.

Characteristics of Microalgae

• Tiny algae spread across the ocean surface like a floating prairie.
• Annually, they produce biomass equivalent to half of all global vegetation.
• Resemble distant galaxies; these organisms are ancient and categorized as protists.
• Most microalgae are single-celled and possess either silica or lime skeletons.

Plant and Animal Distinctions

• The distinction between plant and animal is not clear at this level.
• Some microalgae have limbs that help them rise towards the surface, increasing their exposure to sunlight.

Contribution to the Ecosystem

• Microalgae consume carbon dioxide and produce oxygen.
• Half of the oxygen we breathe comes from these microalgae, making the ocean crucial for life on Earth.

Conclusion

• The ocean is often referred to as the "blue lung" of the planet due to its vital role in oxygen production.
