Photosynthesis
This organelle is where photosynthesis occurs in plant cells.
What is the chloroplast?
The process cells use to release energy from food.
What is cellular respiration?
These levels describe the position an organism holds in a food chain or food web based on how it gets energy.
What are trophic levels?
The element that is recycled through photosynthesis and respiration.
What is carbon?
The pigment that absorbs light energy for photosynthesis.
What is chlorophyll?
This organelle is known as the “powerhouse” of the cell.
What is the mitochondria?
An organism that makes its own food using sunlight.
What is a producer?
The process by which plants absorb carbon dioxide from the atmosphere
What is photosynthesis?
Plants use this gas from the air to make glucose.
What is carbon dioxide?
The main product of cellular respiration that cells use for energy.
What is ATP?
This type of organism breaks down dead matter and recycles nutrients.
What is a decomposer?
This process releases carbon dioxide back into the atmosphere.
What is cellular respiration (or combustion)?
The reactants of photosynthesis
What is carbon dioxide, water, and light energy?
Oxygen is required for this type of cellular respiration.
What is aerobic respiration?
A diagram showing energy transfer between organisms is called a _____.
What is a food web (or food chain)?
Fossil fuels store carbon that was once part of living organisms. True or False?
What is True?
This molecule produced in photosynthesis is used by cells for energy during cellular respiration.
What is glucose?
This simple sugar is broken down during cellular respiration to release energy that cells store as ATP.
What is glucose?
This model shows how energy decreases as it moves from producers to higher-level consumers in an ecosystem.
What is an energy pyramid?
What human activity has the biggest impact on the carbon cycle?
Burning fossil fuels increases CO₂, affecting climate and ecosystems.
