To release energy from glucose
During winter, why do trees appear to "hibernate"?
a. They die completely
b. They store extra water
c. They slow down their metabolic processes
d. They produce more chlorophyll
c. They slow down their metabolic processes
What role do decomposers play in the carbon cycle?
a. They create new carbon
b. They break down dead organisms and return carbon to the soil
c. They perform photosynthesis
d. They store carbon permanently
b. They break down dead organisms and return carbon to the soil
How do plants obtain the water they need for growth?
They absorb it through their roots
Where does photosynthesis primarily take place in plants?
1. Name the part of the plant
2. Name the organelle in that part of the plant
Leaves; Chloroplasts
What happens to glucose during cellular respiration?
It's broken down to release energy
What role do a tree's roots play during winter?
a. They completely stop functioning
b. They store food and remain active
c. They die and regrow in spring
d. They produce new leaves underground
b. They store food and remain active
How does carbon move through an ecosystem?
a. Only through the air
b. Only through plants
c. Through organisms, air, and decomposition
d. Only through water
c. Through organisms, air, and decomposition
What happens when plants are photosynthesizing at a faster rate than cellular respiration?
They produce more oxygen than carbon dioxide
- or -
They take in more carbon dioxide than they release
