According to our textbook, a biotic factor is a living element found within an ecosystem, while an abiotic factor is a nonliving element found within an ecosystem. choose a biome and ecosystem and provide an example of a biotic and abiotic factor found within your biome/ecosystem. explain the importance of these factors to your specific biome/ecosystem.

Before going into the specific biome and ecosystem where I live, let´s talk a bit about what both of these words, what differentiates them and what makes them specific.

A biome is clasiffied, according to National Geographic as a specific region on the planet that is characteristic for the species, both plant and animal, that live on that particular region. In Biomes, abiotic factors, such as light, temperature, presence of water or absence of it, among other qualities, will determine what type of species from fauna and flora will live on that biome, but by description, the Biome focuses more on the living being, and not the abiotic elements. Another important thing is that Biomes can be conformed by various ecosystems.

An ecosystem, on the other hand, is the interaction that exists, on a specific region, between both living and non-living things and that are dependent on an environmental condition. While a Biome is characterized for being a specific geographic region where plant and animal life live, there can be multiple ecosystem within a single, or multiple biomes.

In my case, my biome is a rainforest region of Colombia, on the Andes´ cordillera, where temperature is really low, humidity is really high but there are no seasons and therefore climate is maintained almost constant all the time. These conditions allow for our ecosystems to be rich in water sources,  plenty of rock formations, and plentiful of woods, plant species, fungus and microorganisms, as well as different animal types like birds, bugs, rodents, and other such small animals. We do not have big animals in our biome, or on our ecosystems either.

places of higher salinity. there are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. this evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. this causes the seawater to become denser.
