Leaf-cutter ants harvest leaves and carry them to fungi that convert plant material into a usable form for the ants to digest. The fungi depend on the leaves for nutrients. The ants also produce an antibiotic on their bodies that helps protect the fungi from harmful bacteria. Which of these explains the relationship between the leaf-cutter ants and the fungi?

• Predation, because the ants feed on the fungi 

• Mutualism, because both the ants and the fungi benefit from each other 

• Competition, because both organisms consume the same resource for energy

• Commensalism, because the ants receive energy from the fungi and the fungi are unaffected

Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level?

• Organisms at higher trophic level have less energy available to them than organism at lower trophic levels.

• Organisms at higher trophic levels require smaller habitats that organisms at lower trophic levels.

• Organisms at lower trophic levels provide less energy than organisms at higher trophic levels.

• Organisms at lower trophic levels outcompete organisms at higher trophic levels.
