Scientific Question: How does the amount of soil carbon change with decreasing mangrove height from the coast to inland wetlands?
What is the hypothesis Find the two hypotheses in the Research Background and
underline them. A hypothesis is a proposed explanation for an observation, which can
then be tested with experimentation or other types of studies. Having two alternative
hypotheses means that more than one mechanism may explain a given observation.
Experimentation can determine if one, both, or neither hypotheses are supported.

"Distance from the coast was measured in meters (m) and then broken up into 3 categones. These
categories are closest (10-20 m from coast), intermediate (100-120 m from coast), and furthest (275-300
m from coast).
**Mangrove tree height was measured in meters (m) and then broken up into 3 categories. These
categories are shortest (<1.5 m), intermediate (2-6 m), and tallest (10-20 m),
*** Proportion soil organic carbon is calculated after measuring the difference in soil sample weights
before and after combustion.
