Algae collection
Detailed Description
Algae collected from rocks in the littoral zone of Chandler Lake, Gates of the Arctic National Park. Algae samples are used to establish an energy baseline for the food web, as primary producers – organisms that produce their own food through photosynthesis – algae provide food to the lake’s benthic macroinvertebrates.
