Ecological Succession
BIOXII14: ECOSYSTEM

344530 Read the following statements and select the option stating which ones are true (T) and which ones are false (F).
I. Rooted plants which occur in shallow waters are called macrophytes.
II. Submerged hydrophytes have higher photosynthetic rate than the floating hydrophytes.
III. Detritus is the dried fallen plant matter.
IV. Primary productivity is the rate of synthesis of organic matter by producers.
