Give a scientific reason: Sessile animals are common in aquatic habitats.

(N/A) $1$. In aquatic habitats,water currents constantly flow,which helps in transporting food particles towards the sessile (attached) animals.
$2$. This makes it relatively easy for these organisms to capture food without needing to move.
$3$. In contrast,on land,there are no such consistent currents to bring food to an organism,which is why very few sessile animals have evolved in terrestrial environments.
