answers highly graded a+)
species - CORRECT ANSWERS-group of similar organisms that can breed and
produce fertile offspring
population - CORRECT ANSWERS-group of individuals of the same species that live in
the same area
autotroph - CORRECT ANSWERS-organism that can capture energy from sunlight or
chemicals and use it to produce its own food from inorganic compounds; also called a
producer
producer - CORRECT ANSWERS-organism that can capture energy from sunlight or
chemicals and use it to produce food from inorganic compounds; also called an
autotroph
photosynthesis - CORRECT ANSWERS-process by which plants and some other
organisms use light energy to convert water and carbon dioxide into oxygen and high-
energy carbohydrates such as sugars and starches
chemosythesis - CORRECT ANSWERS-process by which some organisms, such as
certain bacteria, use chemical energy to produce carbohydrates
heterotroph - CORRECT ANSWERS-organism that obtains energy from the foods it
consumes; also called a consumer
consumer - CORRECT ANSWERS-organism that relies on other organisms for its
energy and food supply; also called a heterotroph
herbivore - CORRECT ANSWERS-organism that obtains energy by eating only plants
carnivore - CORRECT ANSWERS-organism that obtains energy by eating animals
detritivore - CORRECT ANSWERS-organism that feeds on plant and animal remains
and other dead matter
, decomposer - CORRECT ANSWERS-organism that breaks down and obtains energy
from dead organic matter
food chain - CORRECT ANSWERS-series of steps in an ecosystem in which organisms
transfer energy by eating and being eaten
phytoplankton - CORRECT ANSWERS-population of algae and other small,
photosynthetic organisms found near the surface of the ocean and forming part of
plankton
food vacuole - CORRECT ANSWERS-small cavity in the cytoplasm of protists that
temporarily stores food
cilium - CORRECT ANSWERS-short hairlike projection similar to a flagellum; produces
movement in many cells
conjugation - CORRECT ANSWERS-form of sexual reproduction in which paramecia
and some prokaryotes exchange genetic information
prokaryote - CORRECT ANSWERS-unicellular organism lacking a nucleus
bacillus - CORRECT ANSWERS-rod-shaped prokaryote
coccus - CORRECT ANSWERS-spherical prokaryote
spirillum - CORRECT ANSWERS-spiral or corkscrew-shaped prokaryote
chemoheterotroph - CORRECT ANSWERS-organism that must take in organic
molecules for both energy and carbon
photoautotroph - CORRECT ANSWERS-organism that uses energy from sunlight to
convert carbon dioxide and water to carbon compounds
obligate aerobe - CORRECT ANSWERS-organism that requires a constant supply of
oxygen in order to live
obligate anaerobe - CORRECT ANSWERS-organism that cannot live in the presence of
oxygen
facultative anaerobe - CORRECT ANSWERS-organism that can survive with or without
oxygen
binary fission - CORRECT ANSWERS-type of asexual reproduction in which an
organism replicates its DNA and divides in half, producing two identical daughter cells
