The water flows through the body of a sponge in the direction that arrows point in this illustration. how does water move through the sponge?

Answer is: in through the pores and out through the osculum.

Water enters the spongocoel (central cavity of sponges) through tiny pores and exits through the osculum (excretory structure).

The spongocoel is filled with choanocytes (collar cells), which have flagella that push water through the spongocoel, creating a current.

Sponges pump large volumes of water, approximately a volume of water equal to the sponge's body size is pumped every five seconds.

Sponges are the members of the phylum Porifera.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

where are the choice options?
