Vedclass · Answer

(D) In an aquatic ecosystem, primary producers are organisms that perform photosynthesis to produce organic matter. $1$. Phytoplankton are the major primary producers in aquatic ecosystems. $2$. Algae also act as primary producers in these ecosystems. $3$. Higher plants (macrophytes) are also present in aquatic ecosystems and contribute to primary production. Since all the options listed ($Phytoplankton$, $Algae$, and $Higher plants$) act as primary producers in an aquatic ecosystem, the correct answer is that none of the options are excluded from being primary producers.

List-$I$	List-$II$
$a$. Carbon dissolved in oceans	$i$. $55$ billion tons
$b$. Annual fixation of carbon through photosynthesis	$ii$. $71 \%$
$c$. $PAR$ captured by plants	$iii$. $4 \times 10^{13} \ kg$
$d$. Productivity of oceans	$iv$. $2$ to $10 \%$
