Olive oil, butter, and margarine all contain: a. carbohydrates
b. lipids
c. nucleic acids
d. proteins

B: Lipids

Explanation:

A lipid has acid and is insoluable in water. Thats why oil sits on top of water. It's not a protein because protein is usually meat, fish, or nuts.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
