PPT-Chapter 6 Multicellular Primary Producers:

Seaweeds and Plants Seaweeds multicellular a few exceptions eukaryotes important source of food habitat producers of oxygen for organisms on land and in oceans economic importance also called MACROPHYTES or MACROALGAE. Some producers rent machinery or perform certain services for a fee To help both custom operators and people who hire custom work done to arrive at a reasonable rate for each service contracted Iowa State University Extension and Outreach conducts a All organisms in an ecosystem need energy to live. Organisms can be grouped by how they get energy. Organisms in an ecosystem are grouped as producers, consumers, or decomposers.. You get your energy from the food you eat..
