  • 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
