1. Coral Bleaching and Temperature Effects – Relationship between rising seawater temperature and the release of healthy and damaged zooxanthellae from coral polyps.

2. Fish Adaptations and Habitat Differences – Differences in swim bladder presence between larval and adult plaice, along with distinguishing features of bony and cartilaginous fish.

3. Mark-Release-Recapture Method – Calculation of sea urchin population size using the Lincoln Index and systematic sampling for coral polyp density measurement.

4. Photosynthesis and Environmental Factors – Seasonal variations in photosynthesis rates, water temperature, and their impact on primary consumer populations.

5. Water Chemistry and Nutrient Cycles – Seasonal fluctuations in nutrient concentrations (phosphates and nitrates) and their effects on marine food webs.

6. Species Diversity and Environmental Correlations – Influence of latitude, sea surface temperature, and primary productivity on razor clam species diversity.
