As there are no answer choices, I'm going to answer this just based off my knowledge
Analogous structures suggest convergent evolution because they have both evolved from a set of species but for different reasons and from different causes.
Crabgrass preventers can be categorized under Residual Herbicides simply because they can stay in the soil for a considerable amount of time and control germination for the weeds. It prevents growth by staying on the ground longer.
Insolation is the amount of solar energy that is incident on the surface of the earth. For the same insolation, water bodies tend to absorb the most heat as water has a high heat capacity and so do grasslands. Areas such as desserts and glaciers do not absorb high amounts of insolation due to which these areas exhibit extreme, inhabitable environments. The order becomes:
The Atlantic Ocean
A marshy wetland
Nevada desert
Polar ice caps
