30s - Q7
Nitrogen in the air must be "fixed" before it can be used by plants. Atmospheric nitrogen is "fixed" by
plants.
bacteria and fungi (decomposers).
bacteria and insects.
bacteria
30s - Q8
When deforestation (cutting down trees) occurs in an area, what immediate effect does this have on the water cycle?
More water is returned to the atmosphere by transpiration
Less is returned to the air by transpiration.
More photosynthesis occurs, and CO2 begins decreasing.
There is less runoff water, but more transpiration.
30s - Q9
The main result of photosynthesis is
CO2 is removed and captured by plants.
absorbing nitrogen for the plant to use.
decreased atmospheric nitrogen.
global warming caused by CO2 being removed.
30s - Q10
Bacteria are involved in many steps of the biogeochemical cycles. Which of the following steps is bacteria NOT involved?
Nitrification
Decomposition
Transpiration
Nitrogen fixation
30s - Q11
Which of the following is common to the carbon cycle, the nitrogen cycle, and the water cycle?
The largest reserves of these substances are always in organisms.
These substances are required by all living things and are involved in many processes that occur in all living things.
The substances are rearranged into different types of molecules as they move through their cycles.
The substances must pass through organisms in order to complete their cycles.
30s - Q12
What is one biotic factor that affects the size of a population in an ecosystem?
Average yearly precipitation
Local geography
Average yearly temperature
Number of predators present

The bodies of dead plants and animals
Scraps of discarded food
Waste products like urine or feces
30s - Q15
Humans increase carbon dioxide (CO2) in the atmosphere, and contribute to the carbon cycle by
using more solar power electricity.
combustion from driving cars
planting trees to improve photosynthesis.
conserving energy with alternative energies
