• Ecology


  The study of how living things interact with one another and the environment
• Parasite


  An organism that survives by living and feeding on other organisms, but rarely kill them
• Habitat


  A description of where an organism is found
• Symbiosis


  A description of any close relationship between two species
• Biotic


  All the living things in an environment such as bacteria, plants, and animals
• Biosphere


  A subdivision of the environment that includes all living and nonliving portions of the planet
• Decomposer


  An organism that consumes dead organisms and organic waste, example-bacteria, fungus
• Food Chain


  A straight-line representation that identifies specific feeding relationships between prey and predator
• Transpiration


  The release of water vapor from the leaves of trees
• Sunlight


  The ultimate source of all energy in most ecosystems
• Correct food chain


  • Snail-Frog-Bird-Fox
• Omnivores


  Animals that feed both on plants and animals
• Nitrogen fixation


  The process where bacteria turn nitrogen into a form that plants can use (ammonia)
• Detritivores


  Organisms that rely on detritus, the decomposing particles of organic matter, for food
• Terrestrial


  Earthworms and some beetles, termites, and maggots
• Marine wetland


  Coastlines in the tropical and subtropical regions fringed with a strip of swamp land which is inundated every high tide with marine and brackish waters
• Energy transfer efficiency


  The amount of energy that is passed from one organism to the next in a food chain is 10%
• Biomass


  The net weight of all organisms living in an ecosystem, which, increases because of its net production
• Greenhouse Effect


  The process by which radiative energy leaving a planetary surface is absorbed by some atmospheric gases
• Tropical rainforests


  The most productive biomes of the Earth and those of greatest biodiversity
• Photosynthesis in water biomes

  Occurs near the surface
• Tundra


  A biome that has low temperatures and permafrost
• Desert


  A biome where the aggravating factor is the water: the precipitations do not arrive at 15 inches per year, whereas the annual average temperature is of 86 F
• Savannah


  A biome where the primary vegetation is grass
• Biome


  A group of ecosystems with similar climates and organisms
• Photoautotrophs


  Autotrophs that are photosynthesizers such as algae and green plants that produce most of the organic nutrients for the biosphere
• Chemautotrophs


  Autotrophs that are bacteria that obtain energy by oxidizing inorganic compounds such as ammonia, nitrites, and sulfides, and they use this energy to synthesize carbohydrates
• Autecology


  The study of the ecology of a single species
• Boreal Forest


  A biome that has mainly coniferous trees
• Autotroph


  An organism that uses light energy to make its own food
• Community


  All the different populations that live and interact in an environment
• Trophic level


  A group of organisms that feed at a particular level in a food chain
• Acidification


  A natural process that causes a decrease in the pH of the ocean
• Autotrophs


  Organisms that produce their own organic nutrients for themselves and other members of the community
• Structural adaptation


  The shape of fish is streamlined over time to move faster in water
• Biodiversity


  The range of different species in the environment
• Shelford's law of tolerance


  Organisms with a wide tolerance limit for environmental factors tend to have high population size with wide distribution
