Which example is an abiotic factor of an aquarium environment? O coral O bacteria O water O sunfish
The Correct Answer and Explanation is:
The correct answer is water.
In an aquarium environment, abiotic factors are non-living components that influence the ecosystem. Water is one of the most significant abiotic factors because it directly affects the living organisms in the aquarium. The quality of the water, including factors like temperature, pH, salinity, and dissolved oxygen levels, plays a critical role in maintaining a healthy environment for aquatic life. For example, if the water temperature is too high or too low, it can stress the fish and other organisms, potentially leading to death. Similarly, water chemistry such as pH or ammonia levels can directly impact the health of the aquarium’s residents.
In contrast, coral and sunfish are living organisms, so they are considered biotic factors. Bacteria, while essential to the ecosystem as decomposers, are also living organisms and thus fall under biotic factors.
Understanding the balance between abiotic and biotic factors in an aquarium is crucial for ensuring that the environment supports the well-being of the organisms. A healthy aquarium relies on maintaining stable water conditions that align with the species’ needs, such as proper filtration systems and regular water changes. Therefore, water quality and the presence of suitable abiotic factors like light and temperature are central to the survival and health of aquatic life in an aquarium.
Ensuring that these abiotic factors are well-maintained, in conjunction with a proper balance of biotic factors, is key to achieving a thriving aquarium ecosystem.
