Vocab Basics
What term describes an organism that makes its own food?
Autotroph
What process do plants use to convert light energy into chemical energy?
Photosynthesis
What process breaks down glucose to release energy for the cell?
Cellular respiration
What gas is a reactant in photosynthesis?
Carbon dioxide
What is the main purpose of photosynthesis?
To produce glucose (stored energy)
What term describes an organism that must consume other organisms for energy?
Heterotroph
What organelle is responsible for photosynthesis?
Chloroplast
What organelle is the site of aerobic respiration?
Mitochondria
What substance is a reactant in both photosynthesis and cellular respiration?
Water
What is the main purpose of cellular respiration?
To release energy from glucose
What molecule is known as the main energy currency of the cell?
Adenosine triphosphate (ATP)
What term refers to substances produced at the end of a chemical reaction?
Products
What type of respiration requires oxygen?
Aerobic
What gas is a product of photosynthesis?
Oxygen
Why is ATP important for cells?
It provides energy for metabolic processes
What term describes organisms that make food and form the base of food chains?
Producers
Why do plants appear green even though they absorb other colors of light?
Chlorophyll reflects green light and absorbs all other colors
What type of respiration does not require oxygen?
Anaerobic
What are the products of cellular respiration?
Carbon dioxide, water, and ATP
Why are producers important in ecosystems?
They make energy available to all other organisms
What term describes organisms that obtain energy by eating other organisms?
Consumers
What term refers to substances needed to start a chemical reaction?
Reactants
What molecule is broken down during cellular respiration?
Glucose
What is the balanced chemical equation for photosynthesis?
6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂
How do producers and consumers interact in ecosystems?
Consumers obtain energy by eating producers or other consumers
