Biome distribution is based on temperature and other abiotic factors influencing the ecological communities to be the same wherever the biome is present across the planet. Biome refers to regions that have a similar climate.
A biome is a region that has similar climatic factors influencing similar patterns of flora and fauna. These regions are also defined geographically as they usually fall within similar latitudes but are influenced by biological communities. However, biomes do not influence the climate pattern of that region, yet it does impact the climate.
Major biomes are characterized by similar vegetation, soil, climate, and wildlife. The major biomes of the world are:
Terrestrial biomes - forest, grassland, desert, and tundra;
Aquatic biomes - freshwater biomes and marine biomes.
They are classified broadly into freshwater and marine biomes.
Tundra biomes are on the other extreme of the temperature scale! They are extremely inhospitable regions that record the lowest temperature on the earth, with soil hardly visible to sunlight. There are two types of tundra:
Characterized by mosses, lichens, grasses, and shrubs which are covered mostly by a frozen soil layer called permafrost
Characterized by pine and evergreen forests.
What is climate and weather? We commonly confuse the two.
It is the weather pattern that happens over a long period in a region of the earth. Biomes are regions showing similar temperature, elevation, humidity, precipitation, wind, and other rainfall patterns.
It is more short term, and can change on an almost hourly basis! Weather-related climatic factors divide the climate into polar, temperate, arid, tropical, Mediterranean, and mountainous zones.
Thus, the biome is a region of the earth locally influenced by the climate factors like precipitation and temperature, which influence other abiotic factors.
1. Why is climate important for biomes?
The Climate Zone is the deciding factor that decides the type of biome. The climate and vice versa influence biome variety, thickness, and spread. When the biome is changed because of human activities, it impacts the climate pattern, which drastically impacts the biome.
2. Are biomes and climate zones the same?
Biomes are regions on the earth that are influenced by similar climate patterns and have similar vegetation and wildlife communities. Climate is the longer trend in the weather that defines the weather pattern in a year in general. So, biomes and climate sones are different.
3. What is a climate region?
A climate region is a region on earth that will have a similar weather pattern over some time. There are different climate regions like polar, temperate, arid, tropical, Mediterranean, and mountainous.
4. What is the difference between biomes and ecosystems?
An ecosystem is the local region and is defined within a particular area where biotic and abiotic components interact. In comparison, biomes are larger regions on the earth influenced by a similar climate pattern, deciding on the flora and fauna types. Biomes will have many locally ecosystems independent of the climate pattern per se, unlike a biome type.
5. Why does temperature define biomes?
Temperature is an abiotic factor that influences several other abiotic factors like rainfall, humidity, and precipitation. So, the temperature is very important in defining the type of biomes.
6. What factors determine biomes besides climate?
Other factors besides climate that decide the type of biome are plant and animal adaptation, biodiversity, and human activity.
7. What is the relationship between climate and latitude?
Latitude is the distance from the equator, with the temperature dropping for every latitude towards the pole. The light rays from the sun, so the energy or heat and light reaching the earth's surface are also less. So, the climate pattern changes with increasing latitude away from the equator – hotter near the equator and colder towards the poles.
