IN: The enteric nervous system (ENS) or intrinsic nervous system is one of the main divisions of the nervous system and consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract. It is now usually referred to as separate from the autonomic nervous system since it has its own independent reflex activity. The ENS is also called the second brain.

IN: Phytoplankton /fatoplktn/ are the autotrophic (self-feeding) components of the plankton community and a key part of oceans, seas and freshwater basin ecosystems. The name comes from the Greek words (phyton), meaning ''plant'', and (planktos), meaning ''wanderer'' or ''drifter''. Most phytoplankton are too small to be individually seen with the unaided eye. However, when present in high enough numbers, some varieties may be noticeable as colored patches on the water surface due to the presence of chlorophyll within their cells and accessory pigments (such as phycobiliproteins or xanthophylls) in some species.
phytoplankton are heterotrophs which depend on autotrophs for nutrition?

IN: The Union and Confederacy quickly raised volunteer and conscription armies that fought mostly in the South over the course of four years. The Union finally won the war when General Robert E. Lee surrendered to General Ulysses S. Grant at the Battle of Appomattox Court House, followed by a series of surrenders by Confederate generals throughout the southern states. Four years of intense combat left 620,000 to 750,000 people dead, more than the number of U.S. military deaths in all other wars combined (at least until approximately the Vietnam War). Much of the South's infrastructure was destroyed, especially the transportation systems. The Confederacy collapsed, slavery was abolished, and 4 million slaves were freed. The Reconstruction Era (1863--1877) overlapped and followed the war, with the process of restoring national unity, strengthening the national government, and granting civil rights to freed slaves throughout the country. The Civil War is the most studied and written about episode in U.S. history.
