Aquatic Primary Producer Life History Traits
The table below presents the typical lifespan and reproduction characteristics of four aquatic primary producers. Based on this information, which of the following correctly ranks the producers from longest lifespan and slowest reproduction to shortest lifespan and fastest reproduction?
| Aquatic Primary Producer | Typical Lifespan/Reproduction Characteristics |
|---|---|
| Seagrasses | Long lifespan, slow reproduction |
| Macroalgae | Moderate lifespan, moderate reproduction |
| Phytoplankton | Short lifespan, rapid reproduction |
| Cyanobacteria | Very short lifespan, very rapid reproduction |
A
Seagrasses, Phytoplankton, Macroalgae, Cyanobacteria
B
Cyanobacteria, Phytoplankton, Macroalgae, Seagrasses
C
Seagrasses, Macroalgae, Phytoplankton, Cyanobacteria
D
Macroalgae, Seagrasses, Phytoplankton, Cyanobacteria; this option muddles the distinctions between lifespan and reproductive rates among the groups.
