Primary producers are the basis for all aquatic and terrestrial food webs. How does the amount of primary production affect community structure?

The primary production has no direct relationship to the community structure.

Explanation:

The primary production has no direct relationship to the community structure. Basically, food web represents feeding relationships within a community The Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem. The more energy available from primary producers, the more species that could be supported at higher trophic levels in the community. In order words, the more energy available from primary producers, the more individuals that could be supported at higher trophic levels in the community
