(18 cards)
Nitrogen Reservoir
Nitrogen Fixation
The movement of carbon through the atmosphere, living organisms, oceans, and Earth’s crust..``
Photosynthesis
Most important life process on Earth
The burning of a substance, releasing CO₂.
Removes CO2 from the air
Water Cohesion
Attraction of water molecules to each other
Water Adhesion
attraction between water molecules and other molecules.
water up a straw
Autotrophs
Organisms that can product their own food from substances in their surroundings
Light - Photosysthesis
Chemical energy - chemosynthesis
Examples - plants, algae, some bacteria
Heterotrophs
Cannot create their own food and rely on other organisms like plants and animals.
Examples - herbivores, omnivores, carnivores
Stages of the nitrogen cycle
Nitrogen fixation
Nitrogen assimilation
Ammonification
Nitrification
Dentrication
What are the main reservoirs of carbon on Earth
Oceans
Fossil Fuels
Atmosphere
Biosphere - living organisms
How do human activities impact the carbon cycle
burning fossil fuels
deforestation
Compare Photosynthesis and cellular respiration
Photosynthesis is the process by which plants convert sunlight into energy, while cellular respiration is the process by which cells release energy from glucose
Photosynthesis is endothermic (requires energy input), while cellular respiration is exothermic (releases energy
Photosynthesis produces glucose and oxygen, while cellular respiration produces carbon dioxide and water
Flux Mechanism
Aerobic Respiration
Anaerobic Respiration is
Chemosynthesis
Specific Heat
Polarity
when an entity contains two distinct and opposite poles that can either attract or repel each other
a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side)
