Genre: a group or classification of items that can incorporate similarities, look, and subject matter. Some movie genres room mystery, horror, comedy, scientific research fiction.

Here we see two different biomes—deserts ~ above the left and also grasslands top top the right. However both are land environments. Pictures by Bob Protus and also Bkell.


To make feeling of complexity, humans frequently need to categorize, or group, things. We have food groups, sexes, eye colors, ages, and also movie genres, to surname a few. We categorize all varieties of things, whether they are principles or objects, and whether they are tiny or large. Among the largest things the we try to categorize may be the varieties of environments found on Earth.

The natural world is more varied than we can imagine, and one method to shot to do this variation easier to handle is to put various environment types into groups. We can divide our surroundings countless ways—by how much water over there is, by how heat it is, or through the varieties of plants or pets we uncover there. Depending on what attributes we choose to explain an environment, the groupings we finish up selecting may it is in different.

Usually we group the different natural locations on earth into categories based upon plant and also animal life and also how they space able to make it through in that part of the world. Make groups based upon living organisms can be an extremely complicated. We already know of end 1.7 million varieties of organism, and also there are likely over 17 million the exist. However again, by grouping organisms with comparable adaptations together, we have the right to see through few of the complexity and also have a chance to better understand the life Earth.

This biome map shows both floor (terrestrial) and also water (aquatic) based habitat types. Click for more detail.


A biology is a type of setting that is defined by the varieties of organisms that live there. Us can likewise think the these as life zones ("bio" means life). Dividing land increase in this waylets us talk around areas that are similar, even if lock on different continents. However depending on who you talk to, the method we division up the world into separate biomes differs.

Biome vs. Biome

Biome categories deserve to be vast or narrow. As soon as we speak forest, friend may snapshot a cool, quiet area with pine trees, whereby bears, deer, and rabbits wander around. Or instead, you could imagine a wet, dark, and noisy rainforest, wherein you have the right to see monkeys, parrots, and large cats.

These room all species of forests, yet some people split them into different forest-type biomes. Click come see more detail.


According to some people, all forest varieties belong in one group – the woodland biome. However others think that temperate woodlands (seasonally cold) v pine trees, are an extremely different indigenous tropical rainforests, through dense, leafy canopy and also lots the rain. This difference of opinion means that the number of biomes can selection anywhere from 5 come 20 biomes.

How different is Different?

Temperate forests get a winter season, often with snow. Tropic rain forests are too heat to get snow. Image by Böhringer.


If we take a closer look at this temperate and also rain forests, we view that lock differ rather a little in the amount of rain castle get and also in your temperatures. Dry rainforests are warm and don"t endure a winter season. Yet temperate forests have a characterized winter, v snow and also temperatures listed below zero.

With those cold temperatures, the plants and animals in temperate rainforests have to have adaptations to resolve cold weather. Execute those teams seem different enough to you to be in a separate biome?

Don"t worry, over there is no right or wrong answer. This method of categorizing is one of convenience, and also sometimes it just depends ~ above why you"re splitting the groups.

Biomes that the World

In bespeak to offer you a little taste of the large diversity the the species of settings out there, we divide the people up right into only nine biomes. Just remember that these groups could likewise be separated into nearly 20 biomes. That method that within every of this biomes there is a selection of temperature and weather conditions, and also we also find part organisms the are adapted to only component of the biome and others that are adjusted to the full selection of conditions within the limits we room defining.
