Unit 6 Investigation Flow of Energy and
Cycling of Matter
Biomass - correct answer-total amount of living tissue within a given trophic level
chlorophyll - correct answer-The green substance (pigment) contained in the
chloroplast of plant leaves that captures the energy in sunlight.
Chloroplast - correct answer-a structure in a plant cell that contains chlorophyll; site
of photosynthesis.
compost bin - correct answer-a collection of decaying plant material; may be used for
fertilizer.
Decomposition - correct answer-the state or process of rotting; decay.
energy pyramid - correct answer-way of showing how energy moves through a food
chain.
Glucose - correct answer-A sugar molecule; product of photosynthesis.
Photosynthesis - correct answer-The process by which a cell captures energy in
sunlight and uses it to make food.
throphic level - correct answer-what an ecosystem is known as in a food web.
Decomposer (saprotroph) - correct answer-An organism that feeds on dead or
decaying organisms or organic wastes.
food chain - correct answer-A series of steps in which organisms transfer energy by
eating and being eaten.
food web - correct answer-a diagram that shows the feeding relationships between
organisms in an ecosystem.
Producer - correct answer-An organism that can make its own food.
Oxygen - correct answer-O2
Respiration in plants - correct answer-Process of using carbon dioxide for energy
and giving off oxygen.
