Answer:
Direct relationship.
Explanation:
There is a direct relationship between water clarity and orca survival because the survival of orca depend on the quality of water. If the water quality is good and clean, the orca survival rate increases whereas if the water quality decreases due to pollution, the orca survival also decreases. The chemicals drained into the water bodies is the main cause of lowering orca survival rate so we can say that both have direct relationship.

Modelling uncertainty limits the accuracy of model predictions. Coral bleaching occurs because the seawater temperature is increasing. This is primarily because of climate change. Predicting climate change in the future is highly uncertain, as it is basically long-term weather prediction that depends on certain carbon emission scenarios. It is well known that normal weather prediction becomes inaccurate after around 14 days, so predicting long-term climate in the next 100 years or more is highly uncertain. There are a multitude of global circulation models (GCMs) that have been developed by different countries, all of which tend to predict widely different climate. Added to this uncertainty is that GCMs work on large spatial scales, and a technique called downscaling is used to predict more localised climate change. Since there are several ways of downscaling, this adds an additional level of uncertainty. Finally, we cannot be sure what carbon emissions will be released to the atmosphere in the future that will drive climate change, another source of uncertainty.
This symbiotic relationship probably developed 1.7 to 2 billion years ago. A few groups of unicellular eukaryotes have only vestigial mitochondria or derived structures: the microsporidians, metamonads, and archamoebae.
Your answer is going to be chicken.
