What does the y-axis show?
1 answer:
The graph below shows a comparison of the plant biomass and soil structure of restored wetlands to that of natural, undisturbed wetlands. This graph could be interpreted to answer the questions below:
- The y-axis show: the percentage of recovery compared to natural wetlands.
- The red graph line represents: the plant biomass.
- After 20 years, the plant biomass restored wetland contains about: 80% of the biomass of a natural wetland.
- The capacity of a restored wetland to absorb nutrients compared to the natural wetland after 55 years is: about 40%.
- It takes longer to restore soil fertility, meanwhile most wetland productivity could be fixed in 50 years. This statement is relevant to data from the graph. Hence, the answer is: supported.
- When a wetland is restored, the ecosystem services that return most rapidly are to: provide food for fish and wildlife.
- “The restoration of a wetland takes about 100 years.” This statement is not relevant to the graph. Hence, it is not supported.
The plant biomass (W) is a relation of the total weight of living plant material to its capacity of doing carbon assimilation. Biomass is the oldest source of energy, so it can be used as an energy source besides the sun. We can find those energies in any organic matter like wood, animal wastes, crops, seaweed, etc.
This question seems incomplete. The complete question is as follows:
“Scientists compared the plant biomass and soil structure of restored wetlands to that of natural, undisturbed wetlands. The graph shows their findings. Can you interpret the graph to answer these questions?”
