Functions of Seaweeds |
Marine organisms encompass a diverse array of life forms adapted to the unique challenges of life in the world's oceans and seas. From microscopic plankton drifting near the ocean's surface to majestic whales traversing its depths, marine life spans a vast spectrum of sizes, shapes, and ecological roles. These organisms play crucial roles in maintaining the health of marine ecosystems, contributing to processes like nutrient cycling, oxygen production, and the regulation of global climate.
Sea grasses are marine flowering plants (angiosperms) with a grass-like appearance, producing flowers, strap-like or oval leaves, and a root system.
The five species of turtles nesting on the Indian coast are Leatherback sea turtle, Green turtle, Olive Ridley, Hawksbill, and Loggerhead turtle.
Eutrophication, siltation, and coastal engineering harm seagrass beds. Eutrophication leads to algal blooms, siltation reduces sunlight penetration, and coastal constructions disrupt natural habitats.
Human-Induced Pressure
Trawling and overexploitation for commerce directly threaten seagrass beds. Trawling damages habitats, while overexploitation depletes seagrass-dependent species, jeopardizing the health and sustainability of these ecosystems.
Seaweeds, macroscopic algae known as thalloid plants, lack true tissues like roots, stems, and leaves.
Eutrophication, siltation, and coastal engineering harm seagrass beds. Eutrophication leads to algal blooms, siltation reduces sunlight penetration, and coastal constructions disrupt natural habitats.
