Question: Identify two abiotic factors whose change would affect the life of the corals?

Two abiotic factors that could significantly affect the life of corals are:

1. Water Temperature: Corals are sensitive to changes in water temperature. They have a narrow range of temperature tolerance, and even a slight increase in water temperature can lead to a process called coral bleaching. Coral bleaching occurs when the symbiotic algae (zooxanthellae) that live within the coral tissues are expelled due to stress from higher temperatures. These algae provide the corals with food and their vibrant colors, so losing them can weaken and eventually kill the coral if the stress persists.

2. Water Quality and Salinity: The quality and salinity of the water also play a crucial role in coral health. Corals thrive in clear and nutrient-poor waters. High levels of nutrients, such as nitrogen and phosphorus, can lead to excessive algae growth, which can smother and shade the corals, hindering their ability to photosynthesize and obtain adequate nutrition. Additionally, changes in salinity (the concentration of salt in the water) can disrupt the delicate balance within coral tissues, affecting their overall health and resilience to stressors.

Both of these factors, among others, contribute to the vulnerability of corals to environmental changes, making them susceptible to degradation and decline in various marine ecosystems. Climate change and human activities, such as pollution and coastal development, can exacerbate these abiotic factors and put corals at risk. Conservation efforts and responsible environmental practices are essential to protect these delicate and valuable marine ecosystems.
