Photosynthetic algae create sugars that will eventually be broken down during which process?
a. glycolysis, during respiration
b. the calvin cycle, during photosynthesis
c. electron transport chain, during respiration
d. the krebs cycle, during photosynthesis

The breaking down of sugars is called glycolysis.
The prefix glyco- meanssugar, and the suffix -lysis means breaking down. It's part of a three-step process in respiration, the other two is The Krebs Cycle and Electron Transport Phosphorylation. In the process of glycolysis, 2 ATP and 2 NADH are produced.

Interacting group of various species in a common location. for example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
