Lakes and ponds:

  • Lakes can be formed by many things such as glacers, volcanoes, and even forest fires.
  • The largest lake in the world is the Caspian Sea in Kazakhstan.
  • Lake superior is the largest lake in the U.S. and America.
  • Ponds are ussually smaller and shallower than lakes.
  • A major pollution problem is fertilizers and soap.

Rivers and streams:

  • All rivers and streams start at some high point.
  • When rivers and streams come together it is called a Watershed.
  • Rivers and streams cause erosian.
  • The Colorodo river made the Grand Canon.
  • A river delta is what is at the end of a river.
  • Rivers are important because they create habitats and provide drinking water.
  • Problems with rivers and streams is pollutants like oil, cans, trash, left over fish hooks.


  • Wetlands are important because they are one of the most productive ecosystems.
  • Wetlands clean, filter, and store water.
  • Wetlands also hold flood waters abd keep river levels normal.
  • The biggest threat to wetlands is urbinization.

Other Biome Characteristics

  • The Ocean biome is suspected to be the oldest of all biomes.
  • The Ocean biome is also the largest biome. It covers 71% of the Earth.
  • Even though the Ocean biome is the largest biome humans have only explored 10% of it.
  • 90% of the ocean is completely dark and receives no sunlight.

Threats to the Aquatic Biome

  • Off shore drilling that result in oil spills
  • Pollution like plastic is harming the sealife.
  • Over-fishing beyond repair
  • some dams block fish migration patterns.
  • Climate change is making the oceans more acidic.

Save The Ocean (And freshwater)

Some ways to save your aquatic biome are:

  • Help clean up- go help pick up trash near the shore.
  • Never throw ANY type of material like plastic, paper, or trash into ocean and freshwater.
  • Spread the info.

Why The Aquatic biome is important.

Why do we need the aquatic biome? How is it essential?

The aquatic biome is neccessary for human life. Not only does it cover most of the Earth it also provides one of the most major needs for all life, water.

The Forests; by Caleb J., David M., Elijah R., Gideon W., Kamie C.

The Forest Biome is very large and spans a wide portion of the globe. However, this biome can be split into three different categories: the Temperate Forest, the Tropical Forest, and the Boreal Forest.
Big image

The Tropical Forest

The Tropical Forest, otherwise known as the rainforest, is found a bit south of the Equator in the (surprise) Tropics! It is an essential piece of Earth's biomes.

Climate Characteristics

Temperature: On average, the temperature of the tropical forests range from about 68 - 77 °F.

Rainfall: There is much rain in the tropical forests. On average, they annually receive more than 200 cm. Though, in the Amazon Jungle, there can be more than 300 cm in a month!

There are really only two seasons in the Tropical Rainforest: wet and dry! The wettest month for the Amazon is mid February. This is when there is widespread precipitation over all of the Amazon rainforest.

Keystone Flora and Fauna

In the rainforest biome, there are more producers than there are consumers.

Flora: Because of the higher temperatures and wealth of sunlight, there are many big, green trees (courtesy of large of chlorophyll produced during photosynthesis). Among these trees are, Banana Trees, Coconut Trees, and Brazilian Nut Trees. There are also many flowers, such as the Passion Flower, the Peace Lilly, and the Hot Lips flower.

Fauna: As stated above, there are many more species of producers than consumers in the rainforest, thought there are many consumers. Among them are Poison Arrow Frogs, Boa Constrictors, Jaguars, and Spider Monkeys.

Here is an example of what a food web in a rainforest might look like. Notice that the bottom level holds producers, and there are many more of those than the consumers at the top!

More about Tropical Forests!

  • One square kilometer of rainforest can contain as many as 100 different tree species!
  • Some trees can grow to be 25 to 35 m. tall!
  • Even though you may think of a rainforest as being relatively flat, there are mountains, valleys, streams, wetlands, and rivers all in one forest!

The Boreal Forest

The Boreal Forest, sometimes known as the Taiga, can be found in the northern latitudes of Earth. It is certainly a vital part of Earth's biomes.

Climate Characteristics

Temperature: In the Taiga, temperatures can range from an average of -65 °F to 86 °F.

Rainfall: Precipitation occurs sparingly in the Taiga, but it can accumulate from 40 to 100 cm of precipitation annually, usually in the form of snow. However, some areas of Russia get almost 134 cm of snow a year!

The Taiga is dominated by winds that are brought from the Arctic Circle, that brings cold weather to the biome.

The Taiga is also known for its extreme cold, especially during winter months, and short summers. Winters have been known to last as long as seven months, and due to Earth's tilt, the Taiga receives little sunlight.

Big image

Keystone Flora and Fauna

Flora: Vegetation in the Taiga is harsh and sparsely located, due to its harsh climate. Very little plants are able to survive in this climate; some of these include moss and lichen such as the Polytrichum moss and the British soldiers lichen. Most of the vegetation in the Taiga are coniferous trees, such as firs, pines, spruces, hemlocks, and larches.
Fauna: Animals in the Taiga are mostly predators, such as the lynx, tiger, wolverine, fox, and bobcat. These predators hunt herbivores like red squirrels, voles, and snowshoe rabbits. In the more deciduous regions of the Taiga, elk, moose, and red deer can be found.
Big image

In this picture, you can see an example of a food chain in the Taiga biome. Notice the top predators are the Tertiary Consumers.

More about the Taiga!

  • The Taiga happens to be the world's largest terrestrial biome!
  • The soil within the Taiga is very poor and lacks nutrients due to intense weathering!
  • Surprisingly, this biome contains a high amount of diversity between birds and mammals!
  • You can quickly characterize the Boreal Forest by its coniferous trees.

The Temperate Forest

The Temperate Forests are usually found above the Equator. They are in between the Tropical and the Boreal forest biomes, though. This is the last piece in the overarching 'Forest' biome.

Climate Characteristics

Temperature: Within the Temperate Forest biome, the mean temperature typically ranges from 50 - 70 °F.

Rainfall: There isn't as much rain in the Temperate forest as there is in the Rain forest, but there is certainly more than in the Taiga. The average amount of rainfall is 75 - 150 cm a year.

The Temperate forest biome has very fertile soil that allows large healthy plants to grow. Unlike the Tropical forests, this forest does have the regular four seasons, as opposed to just wet and dry.

Keystone Flora and Fauna

Flora: North Carolina is part of the Temperate forest biome, so if you go to a forest near your house you might see some of the plants mentioned below. There are many trees, such as Fir trees, Oak trees, Beech trees, etc. There are also many ferns, mosses, shrubs, and flowers that can be found here.
Fauna: Some of the tertiary consumers, you might see in your back yard, but more likely, you will see more of the secondary or primary consumers (see food web below). Some of the animals found in the Temperate forest biome are shrews, weasels, raccoons, elk, deer, wolves, etc.

The conopy layer, understory layer, and ground layer describe the different trees that grow to that height, that are categorized in that layer.

Extras about the Temperate Forest!

  • There are mainly only remnants of the forests left due to both fire and deforesation.
  • Temperate forests take years, even decades to fully mature, due to the immense size of many of the trees found here.
  • Temperate forests are usually very hilly.
  • The flat areas generally have many, many trees and shrubs.

Our Forests are in Trouble!

The forest biome, mentioned above, it home to many different ecosystems. Many of these living things are very rare, and need to be protected. In addition, the trees in the forests help protect against soil erosion and flash flooding, which would occur without them. Of course, the flora within the forests also help produce oxygen and reduce the amount of carbon dioxide.

The forests are very clearly vital to the Earth! However, some don't see this need of protection.

In fact, several terrifying things are at work in the forests.

Forests are being cut down for paper, and the increasing need for fossil fuels causes several ecosystems to be damaged in the search, along with polluting the air and endangering species'. This clear cutting also contributes to the global warming of Earth's atmosphere, as well as creating an ecological imbalance. Hunters within the forest biome are killing the animals inside, pushing several species near the brink of extinction! The situation is grim, yet few seem to see the need! Spread the word and do what you can to save our forests!!

Climate Characteristics

Temperature: In the summer, temperatures get well over 100 degrees Fahrenheit. In the winter, temperatures can get down as low as -40 degrees Fahrenheit.

Rainfall: The grasslands get 10-35 inches of rain per year, which happens mostly in the spring,

Other: Seasonal drought and fires help maintain grasslands.

Keystone Flora and Fauna

Flora: grasses are the primary vegetation, but there is also a variety of plants such as: prairie rose, gumweed, gumbo primrose, spiderwart, golden rod, clover, sild indigo, and coneflower.


North American Grasslands: bison, elk, jack rabbits, prairie dogs, burrowing owls, golden eagles, coyotes, and badgers
