Ralph is assessing **abiotic factors**. These are the non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems, such as temperature, light, and water availability.

Suzy’s brother MOST likely dropped his toy **in a pond**. Still bodies of water, such as ponds, are often characterized by calm surfaces that can have vegetation like green moss.

After the storm, we would MOST expect to find **decreased salinity because a large amount of fresh water would flow in**. The heavy rain would increase the amount of fresh water entering the lagoons, diluting the salinity.

Tim can MOST likely predict that **the water will be cold and high in dissolved oxygen**. Kelp forests typically thrive in colder, nutrient-rich waters, and these environments often have high levels of dissolved oxygen due to the photosynthetic activity of the kelp.
