L11 & L12 (Exam 2) Flashcards
Macrophytes
Bryophytes: mosses,
angiosperms: flowering plants
Four major Macrophyte groups:
- Emergent (rooted in or near water)
- Submerged (attached to substrate)
- Floating-leaves (rooted in shallows w/floating leaves)
- Free-floating (form mats

FFGs
organized by food sources and mechanisms of acquiring food
Instream food sources:
- Periphyton
- CPOM
- FPOM
- animal prey
