Merenelävillä

Merenelävillä refers to a group of organisms that live in marine environments, including the ocean, seas, and coastal waters. This term encompasses a wide range of species, from microscopic plankton to large marine mammals. Merenelävillä play a crucial role in marine ecosystems, contributing to biodiversity and supporting various food chains. They include phytoplankton, which form the base of the marine food web, and zooplankton, which feed on phytoplankton and are, in turn, consumed by larger organisms. Fish, both pelagic and demersal, are also part of merenelävillä, providing sustenance for predators and humans alike. Marine mammals such as whales, dolphins, and seals, as well as sea turtles and marine birds, are also included in this category. These organisms are adapted to life in saltwater, with unique physiological and behavioral characteristics that allow them to thrive in their aquatic habitats. Merenelävillä are subject to various threats, including pollution, overfishing, climate change, and habitat destruction, which can disrupt marine ecosystems and endanger their survival. Conservation efforts are essential to protect merenelävillä and maintain the health of marine environments.
