Biomes are defined as a world’s largest communities, and classified according to animals and plants of a particular environment. Abiotic factors are what characterizes a certain biome. Abiotic factors are non-living factors such as climate, pH, temperature, and etc. Abiotic factors in one way dictate the kind of organisms that thrive in the biome, only those that are able to adapt there are those that can thrive. A biome differs from an ecosystem. An ecosystem includes both biotic and abiotic factors in a certain area, and how these factors interact with each other. While biomes would include the abiotic and biotic factors that a geographic area would include the organisms living in there.
Botanists, ecologists, biologists, anthropologists, and climatologists, classify biomes in different ways. Some classifies them into 6 types of biomes. These are Tundra, Grassland, Forest, Desert, Marine, and Freshwater. Other scientist classifies them into different biomes, these are Tropical rainforest, Deciduous forest, and Taiga.
Tundra is known as the coldest type of biomes, and also has two types: Arctic Tundra and Alphine Tundra. Grasslands are lands dominated with hectares of grass than tress. Desert is characterized as the hot and dry, coastal, semiarid, and lastly cold. Marine biomes cover the ¾ surface of earth. Freshwater, have less than 1% of salt concentration. Taiga, on the other hand, is the largest biome in the world and can be found in cold regions. Deciduous forests, known as the most notable because they can survive 4 seasons and they can be found in Eastern US, China, Canada, Europe, and Japan. Tropical rainforest are located near the equator, which lies in areas of heavy rainfalls.
Autotrophic organisms can subsist in an exclusively inorganic environment because they can manufacture their own complex organic compounds from inorganic raw materials taken from the surrounding media. Since the molecules of these raw materials are small enough and soluble enough to pass through cell membranes, autotrorophic organisms do not need to pretreat, or digest their nutrients before taking them into their cells.
Heterotrophic organisms mostly bacteria, fungi, and animals are incapable of manufacturing their own complex organic compounds from simple inorganic nutrients. Hence they must obtain prefabricated molecules from the environment. Many of the organic molecules found in nature are too large to be absorbed unaltered through cell membranes, and they must first be broken down into smaller, more easily absorbable molecule units and they must be digested.
Autotrophs and Heterotrophs can be found in biomes, since biomes are geographic area that has an organisms living in there. Autotrophs, obtains chemical energy through oxidation to make an organic substance from an inorganic substance, through the use of photosynthesis which utilizes light energy and by obtaining nutrients. While Heterotrophs, depend on autotrophs for organic substance since it’s organism are unable to produce organic substance from inorganic ones. Heterotrophs depend on autotrophs for organic substances, which heterotrophs will utilize to produce energy. Both play an essential roles in food chains and nutrient cycling.
The absence of one member or one abiotic factor can affect all the parties of the ecosystem. It is because, biotic members of an ecosystem, together with their abiotic factors depend on each other. Ecosystems are the foundations of the biosphere and they determine the health of the entire earth system. It is a vital life-support that provide services to human life, its well-being and to social development. Unfortunately, ecosystems have been disrupted and even destroyed by natural calamities such as floods, earthquakes, storms and volcanic eruptions. Abuse of human activities or human actions to the environment have also contributed to the disturbance of many ecosystems and biomes.
