BIOL 1108 Study Guide - Midterm Guide: Hydrogen Sulfide, Nitrogen Cycle, Deep Sea
Document Summary
Chapter 48 - biomes and global ecology (review) Sea stars, sea urchins, barnacles, mollusks, corals. Algal symbionts, free living algae, invertebrates, and fish. Neither close to the shore nor the seafloor, forms the bulk of the oceanic system, sunlight permits photosynthesis in upper part of the column, animals less abundant at depth, Limited biomass; high species diversity; dense animal populations; hydrothermal vents expel fluids containing high abundances of hydrogen, hydrogen sulfide, and methane; and high levels of primary production by chemosynthetic bacteria. The cycles of carbon and other biologically important elements that link organisms and their environment in the chemical cycling of the raw materials needed for life. The biological carbon cycle shapes ecological interactions and reflects evolution. All of the ecological complexity of ecosystems and biomes begins with primary producers that convert carbon dioxide into organic molecules. Primary production on land is dominated by vascular plants.
