Cycling of Matter and Flow of Energy Key Terms
1 ecosystem- (book G) All the living and nonliving things that interact in an area.
2
biotic factors-(book G) a living part of an ecosystem
3
abiotic factors-(book G) a nonliving part of an ecosystem
4
habitat-(book G) the place where an organism lives and that provides the things the
organism needs
5
species-(book G) a group of similar organisms whose members can mate with one
another and produce fertile offspring
6
niche-(book G) an organism’s particular role in an ecosystem, or how it makes its living
7
producers-(book G) an organism that can make its own food
8
consumers-(book G) an organism that obtains energy by feeding on other organisms
9
herbivore-(book G) an animal that eats only plants
10 carnivore-(book G) an animal that eats only other animals
11 omnivore-(book G) an animal that eats both plants and animals.
12 scavenger-(book G) a carnivore that feeds on the bodies of dead organisms
13 decomposer-(book G) an organism that breaks down large molecules from dead
organisms into small molecules and returns important materials to the environment
14 food chain-(book G) a series of events in which one organism eats another and obtains
energy

16 energy pyramid-(book G) a diagram that shows the amount of energy that moves from
one feeding level to another in a food web
17 biome-(book) a group of ecosystems with similar climates and organisms
18 biomass-(ss) matter formed by plants or animals that is used as a fuel, such as wood or
dung.
19 compost bin-(ss338) it made up of discarded fruit and vegetable material, yard waste,
and other plant materials
20 autotroph-(powerpoint) primary producers
21 heterotroph-(ss) an organism that obtains the energy it needs by feeding on other
organisms
22 trophic level- (pp) the position an organisms occupies in a food chain
23 radiant energy-(pp) light energy that travels in waves and supplies the earth with almost
all of our energy.
24 predator-(book) a carnivore that hunts and kills other animals for food and that has
adaptations that help it capture the animals it preys upon
25 evaporation-(ss) is the process in which liquid water changes into invisible water vapor.
26 denitrification-(pp) is the process where nitrogen compounds are turned back into
atmospheric nitrogen.
27 matter-(ss) anything that has mass and takes up space
28 condensation-(ss) is the process in which water vapor changes into liquid water.

29 nitrogen fixing bacteria-(pp) are bacteria that take atmospheric nitrogen and change it
into useful nitrogen compounds that plant and animals can use.
30 transpiration-(ss) water vapor is released to the air from the leaves of plants.
31 prey-(book) an animal that a predator feeds upon
32 precipitation-(ss) occurs when water or a form of ice falls from the atmosphere to Earth’s
surface.
