Use the information and the tables to answer the following question. The tables show fossil evidence found in one area during three different time periods.
The environment during Time period 1 was very hot and rainy. Over time, the environment became much drier.
What can you conclude from this information?
A. Fossil C survived best in a rainy environment because there is a large population of them in Time period 3.
B. Fossil B struggled to survive in a dry environment because there are none of Fossil B in Time Period 1.
C. Fossil C was best adapted for a dry environment because their population increased in Time Period 3.
D. Fossil A was better adapted to a dry environment because there is a larger population of them in Time Period 1.

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
