Warm air above the ocean rises making room for cooler air from the land
Photosynthesising primary producers require sunlight. Therefore, in the ocean, phytoplankton would be concentrated within the surface layers of the ocean where the sunlight penetrates. Phytoplankton support a wide range of marine life: zooplankton feed on phytoplankton, which in turn support fish and so on.
Dr. Alvarez is doing research on the subfield of psychology called the behavioral neuroscience. Scientists from the field study the biological foundation of human behavioral characteristics. These scientists are trying to find out what physiological processes and anatomical structures are involved in certain aspects of human behavior.
