Marine life is a topic that can be discussed on many levels, from the microscopic to the global. In every ocean, in every sea, there is a wide array of species, each with its own unique qualities. There are some species we know about and some that we don’t. The oceans cover about 70% of the Earth’s surface, so it’s impossible for us to know everything this planet has to offer.

What is an Oceans and Marine Life?

In the world of oceans and marine life, there are many different types of creatures that inhabit both the freshwater and saltwater environments. From tiny plankton to massive whales, these aquatic creatures play a vital role in the food chain and maintain ecosystems all over the world.

One of the most popular groups of ocean creatures is fish. There are more than five thousand different species of fish in our oceans, and each one has its own unique characteristics. For example, some fish live in shallow waters while others swim in deep seas. Some fish eat plankton while others eat other fishes or sea mammals.

Another type of ocean creature is coral. Coral reefs are found all over the world. They provide a home for a vast number of marine life forms. These reefs are made up of small coral polyps (a type of animal), and they grow slowly over many years. Coral can be found at depths ranging from shallow water near the shore to thousands of feet underwater in the open ocean.

The sea floor is home to another group of ocean creatures called mollusks. Mollusks include clams, oysters, squid, and snails. They are very slow-moving animals that can live for hundreds or even thousands of years without ever moving from their home on the sea floor. Some other types of ocean creatures include dolphins, whales, manatees, sharks, seagulls, jellyfish, and squids. Each one has its

What is the water’s role in our atmosphere?

The ocean is a vast and vital body of water that covers more than two-thirds of the earth’s surface. It is home to a wide range of marine life, from tiny plankton to huge whales and dolphins. The ocean also plays an important role in the Earth’s atmosphere.

Water molecules (H2O) are big and contain a lot of oxygen, which helps break down pollutants in the air. In fact, the ocean makes up about 23 percent of the Earth’s total atmosphere! And since the oceans are constantly taking in air and releasing water, they play an important role in regulating our planet’s climate.

What are marine ecosystems?

Marine ecosystems are communities of marine life that live in salt water. These systems can be found all over the world and are made up of a variety of different creatures. Marine ecosystems play an important role in the economy and environment. They provide food for humans and other animals, clean up pollution, and support tourism.

Factors influencing global changes in ocean chemistry

Over the last several decades, there has been a significant increase in the levels of carbon dioxide (CO2) in the atmosphere. This increased concentration of CO2 is causing global changes in ocean chemistry and biology. There are a number of factors influencing these changes, including variations in wind patterns, emissions from human activities, and natural variability.

One key consequence of increased CO2 levels is that the ocean becomes more acidic. As CO2 dissolves into seawater, it forms a weak acidity molecule (H+). This greater acidity decreases the pH level of oceans. It can damage marine life by removing essential nutrients or making them more susceptible to infection. In addition to harming marine life, high levels of acidity also reduce the availability of calcium for coral reefs and other calcifying organisms.

A second major consequence of increased CO2 levels is that they lead to an increase in ocean temperatures. Higher temperatures cause water vapors to rise up into the atmosphere. Where they trap more heat energy and contribute to global warming. As a result, higher temperatures are also associated with an increased prevalence of algae species. They use sunlight to photosynthesize (produce energy from light). The algae growth can block sunlight from reaching other marine life, leading to their displacement or extinction. Other consequences of high CO2 levels include an increase in sea level as the water expands due to thermal expansion and an increase in coastal erosion as wave action erodes shorelines faster than they are replaced by new sediment

Ocean acidification; how it affects marine life

Ocean acidification is caused by the increase in atmospheric CO2, which makes it harder for the ocean to form shells and skeletons of calcium carbonate. This can harm marine life by making it difficult for them to form their hard exterior shells or skeletons. Signs that ocean acidification is happening include increased coral bleaching and lower pH levels.

In addition to harming marine life directly, ocean acidification also affects the food chain. Marine creatures eat smaller organisms, which in turn eat plankton. When there are fewer plankton because of higher pH levels, this can lead to decreased populations of larger fish and mammals.
