The Components of the Ocean Biome
A biome, also known as life zones, consists of all plants, animals, and other organisms, as
well the physical enviorment in a particular area. A biome is characterized by its plant life,
climate, and location. The climate and physical features determine the boundaries of a
biome. A biome is made up of many different ecosystems. The ecosystems tend to have
the same plants and animals as neighboring biomes around the boundaries.
The oceans and seas form the marine biome, the world's largest biome. It covers
three-quarters of the earth or 70 percent of the worlds area and reaches from the far north
to the far south of the planet. Oceans are filled with salt water. Their climate stays the
same year round, so the creatures of the sea do not have to adapt to the changing seasons.
There are five oceans: the Atlantic, Pacific, Indian, Artic, and Southern (Antarctic),
although three of these: Atlantic, Pacific and Indian are regarded as the principal oceans.
The Arctic Ocean is regarded by some researches as part of the Atlantic. The Southern
Oces is really the southernmost part of the Atlantic and Pacific. It is bordered by the
continent of Antarctica to the south, but has no land bordering it to the north. The oceans
include seas- smaller expanses of marine waters. Among the largest seas are the
Mediterranean, Caribbean, Yellow, South and East China Seas, and the Sea of Japan.
Near the poles, in the far north and south, the sea is always cold, and in the winter its
surface freezes. When water freezes, any substances dissolved in it are "squeezed out"
from the ice. At the edge of the ice the sea is saltier than it is farther away. Salt water is
denser than fresh water because of the salt in it. Water also reaches it maximum density at
39 degrees F, just above freezing. Cold water flowing toward the equator is replaced by
warmer water, and this exchange of water produces the principal ocean currents. They
flow in approximate circles, called gyres, in all oceans.
The climate of the ocean does not vary much throughout the seasonaly changes. it does
not change because water does not heat up or cool down quickly. The ocean carries
warm and cool currents that heat or cool the land it goes by. For example, Hawaii is
warm due to the warm currents that are being swept onto the land which ir surrounds.
What is a biome? Biomes are major life zones characterized by vegetation type or by the physical environment. Climate plays a role in determining the nature and location of Earth’s biomes. Texas has 10 different ecosystems with lots of diversity. Minnesota has 4 different ecosystems which are also quite diverse. Regardless of the size of the biomes or the number of biomes in each state, they are all important not just to the locate environment but on a global level because of the life they support. We are going to take a look at the different biomes, comparing climate and rainfall, as well as vegetation fauna.
1. Life is more abundant in the North Atlantic than in the Pacific because the ocean area of the North Atlantic is directly in the path of iron-rich dust from the Sahara Desert, which leads to the development of bigger communities of phytoplankton, and in turn plankton, and so on. This fact is related to global warming because someone thought of an idea to fight global warming by putting huge amounts of iron solution into the ocean so that extreme plant growth would occur and these plants would remove enough carbon dioxide out of the atmosphere to counter the negative effects of humans.
The national park is part of the North Pacific Coastal Ecological Community biome. Another biome in the park is their temperate forest. Temperate forests have high humidity, high levels of precipitation, and variety of trees are also included. Freshwater biomes surround the park as well. Glacier Bay national park provides five different types of ecosystems.
The ice caps are the most extreme climates on earth. They are located at the north and south poles. These poles are
months and the summers are cool and short. Also due to the fact that much of

Change in water temperature changes the places where grasses are able to grow, when fish and crab feed, reproduce, and migrate ("Chesapeake Bay Program"). The temperature in the bay goes from high in the summer to very low in the winter. During summer, the surface water is warmer than the deeper water, which creates two different temperature layers that actually separate surface waters from deeper waters (“Chesapeake Bay Program”). The temperature layers change the summer dissolved oxygen levels.... ...

The average winter temperature is about -30°F and average summer temperature is roughly 37-54°F. The yearly amount of precipitation, which includes melting snow, averages about 6 to 10 inches. With these conditions, it makes for a short growing season of about 50-60 days. In some parts, it can be up to 180 days. This is only found in the southern part of the tundra.

Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra.
The weather here in the U.S.changes seasonally. We have four different season here. The different seasons are spring, summer, fall, and winter. These seasons change due to the earth’s tilt of the axis. The way the earth tilts affects the season so if it tilts further downward it’ll start getting warmer but when it tilts up it’ll start to get
Biodiversity refers to wide diversity found in the living components of the earth which refers to the numerous varieties of flora and fauna including those of microorganisms too. The interaction of biotic and abiotic components of the ecosystem is very important aspect of life on earth. Biodiversity helps us to understand the variations among species and also how life originated on earth. Its study helps us to understand the inter-relationship between various forms of life and their adaptation to different conditions.
