Answer:Algae contributes to the phosphorus cycle

Explanation:Algae are organisms which have distinct chlorophyll and are autotrophic in nature .Most of them live in water.Algae include the Unicellular chlamydomanas and the multicellular sea weed.some algae are colonial and some are filamentuous.Algae possess chlorophyll, carotenoids and phycobillins as pigments.

Algae are important primary producers in the water bodies and produces a significant portion of oxygen.

Some algae eg diatoms are fossilized due to their glass cell wall and are known as diatomaceous earth, which has various uses such as abrasives,tooth paste and as filters.

Red algae produces calcium carbonate which forms coral reefs.

The products of some algae are used as solid gels and source of agar for microorganism culture.

Match the functional groups with their structures:
evablogger [386]
The true answer of your question is :

OH : HYDROXYL GROUP

NH2 : AMINO GROUP

CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )

COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

I hope you’ll understand everything, anyway if not i’m always here to help. ♥️
