The importance of Biomes
Biomes are the living spaces of life. They describe communities located across different regions across the world, looking at the interactions between climatic factors, living organisms, and substrates found in the environment. Generally, a biome refers to a community of similar organisms that are found in a particular climate zone. There are six biomes of earth found in three climate zones. The three climate zones are called tropical, temperate, and polar climate zones; and the six biomes of earth are deserts, grasslands, temperate deciduous forests, rainforests, taiga, and tundras.

Biomes are generally differentiated on the basis of the temperature and precipitation that each region receives. Some of these biomes are known for their harsh climates, such as the tundra and the taiga, while others are known for their beautiful greenery and biodiversity, like the rainforest. While each biome is diverse and important in its own respect, together they actually define our Earth and sustain all the life found on it. Deserts are just as important to this planet as are, and it is with all the biomes of Earth together that life is sustained.
Each biome alone for our planet, and together they actually define our Earth and all its variety. Some people may hate the desert, but even the desert plays an important role in maintaining Earth and all the life in it.
Lets go ahead and take a look at what each of Earth’s biomes has to offer.
Equatorial and tropical climate zones
We begin our exploration in the equatorial and tropical climate zones. Imagine you are in a spot about 20 degrees north or south of the equator, where daily temperatures variations is greater than monthly temperature variation; environments in this area are distinguished by seasonal rainfall patterns. It is really warm here, so plants and animals never have to worry about freezing. As you’re walking, you find yourself immersed in a sea of dark greenery and tall trees—you’ve just walked into a tropical rainforest! [lecture]
Tropical rainforest have the greatest diversity of species compared to all the other biomes on Earth, and you’ll only find that there are only two seasons here: rainy season and dry season. Its dark here because a canopy of green blocks light from coming in, and soils beneath your foot are generally nutrient poor and acidic. In just one square kilometer, you may find over a 100 different flora species, with tall trees that are about 25-35 km tall, covered in mosses and surrounded by ferns, orchids, and palms. Depending on what type of rain forest you are in, you’ll find small mammals, bats, insects, and various species of birds all around you.

The next biome in this climate zone falls is a division of the grassland biome, otherwise known as tropical grasslands, or savannas. Savannas are essentially grasslands, but with scattered trees. Nearly two-thirds of the...
