Biology Matter and Energy Quiz Flashcards
Study Guide (35 cards)
Biosphere
Parts of the Earth where life exists. An area that contains all living organisms and the products of their activities.
Matter
Something that occupies space and has mass.
Energy
Ability to do work. Cannot be created or destroyed, just change forms.
Food Chain
Single pathway of how food (matter and energy) moves through the organisms in an ecosystem.
Food Web
All the possible food chains in the ecosystem.
Ecosystem
Geographic area where living (plants, animals, and other organisms) and nonliving (weather, water and landscape), work together to form a bubble of life.
Producer/ Autotroph
Uses sun’s energy and nutrients to make food.
Consumer/ Heterotroph
Eat producers or other consumers to make food.
Decomposer
Breaks down dead organisms and other waste. Cycle nutrients.
Carbon Cycle
Cycling of carbon through different reservoirs (atmosphere, fossil fuels, ocean, plants, etc.) found on earth, living and nonliving.
Fossil Fuels
Materials such as coal, oil and natural gas, formed naturally in the Earths crust from the remains of dead animals and plants that is extracted and burned as a fuel.
Stomata
Tiny openings on the leaves that allow gas exchange in and out; key part of photosynthesis.
Chloroplast
Plant organelle that contains chlorophyll, where photosynthesis takes place.
Chlorophyll
Green pigment in chloroplasts that absorbs energy from sunlight.
Mitochondria
Cell organelle where cellular respiration takes place to make ATP.
Photosynthesis
Process that autotrophs perform. Use sunlight energy to convert water and carbon dioxide into sugar (glucose) and oxygen.
Cell Respiration
Process by which cells release energy by breaking down glucose molecules. The energy from glucose is released in the form of ATP molecules.
ATP
Chemical compound that cells use to store and release energy; product of cell respiration.
Carbon Dioxide
CO2 gas that is a product of Cell respiration and a reactant of photosynthesis.
Glucose
Sugar/ C6H12O6; chemical energy produced during photosynthesis from light energy. Reactant in cellular respiration.
Oxygen
O2 gas that is a product of photosynthesis and a reactant of cell respiration.
Product
Element or compound that is PRODUCED by the chemical reaction (Think the end results)
Reactant
Element or compound that ENTERS a chemical reaction (Think the ingredients)
Water
H2O; liquid or vapor that is a reactant of photosynthesis and a product of respiration.
