What is the main purpose of cellular respiration?
To convert energy stored in food (glucose) into usable energy (ATP).
What is a nutrient cycle?
What is The movement and exchange of essential elements (like carbon, nitrogen, and phosphorus) through living organisms and the environment.
Photosynthesis does not occur when the sky is overcast.
False
In which organelle does aerobic respiration take place?
What is the mitochondrion (the powerhouse of the cell)
What role do decomposers play in nutrient cycles?
What are They break down organic matter and return nutrients to the soil, air, and water?
If I keep a plant locked up in my closet (no windows) and expose it to artificial light it will photosynthesize
TRUE
A __________ is an ecosystem that has collapsed: central functions have ceased.
What are Deadzones?
What gas is consumed and what gas is released during cellular respiration?
What is Oxygen is consumed, carbon dioxide is released.
Which process converts atmospheric nitrogen (N₂) into usable forms for plants?
What is Nitrogen fixation?
Aquatic Plants go through photosynthesis.
TRUE
What molecule is the main energy currency produced by cellular respiration?/What happens to glucose during cellular respiration?
What is ATP?
What is It is broken down to release energy, forming CO₂ and H₂O.
How do human activities disrupt nutrient cycles?
What is Fertilizer use, deforestation, agriculture, industrial emissions, wastewater discharge, fossil fuel combustion, and soil erosion.
________ Nutrients are those that are scarce
enough that they limit growth: if the organism
runs out, it can't keep growing (or thriving)
What are Limited Nutrients?
eg Nitrogen (N) and phosphorus (P)
Plants only photosynthesize; they do not respire.
What is false?
How are photosynthesis and cellular respiration connected in the carbon cycle?
What is The products of photosynthesis (glucose and oxygen) are the reactants for respiration, and the products of respiration (CO₂ and water) are the reactants for photosynthesis.
What helps with nitrogen fixation?
What are nitrogen fixing bacteria, lightning, volcanoes?
What came first, photosynthesis or respiration?
What is photosynthesis?
Vegans and vegetarians are not heterotrophs.
What is false?
