Question

Porifera are one major phylum of invertebrates. Porifera are commonly called sponges. They have porous bodies without any organs. In fact, they are very simple organisms. They don’t even have mouths. Sponges live in water, which they filter through their bodies. That’s how they capture food. Sponges’ bodies are asymmetric. That means that they don’t have symmetry. No two halves of their bodies line up.

Sponges’ porous bodies help them to (what?)
a) food from the sun.
b) their prey.
c) capture food.
d) reproduce.

Answer 1

Sponges are filter feeders that capture food by filtering water through their porous bodies, facilitated by the movement of water driven by flagella in their cells.

Step-by-step explanation:

Sponges, belonging to the phylum Porifera, are filter feeders . This means that they pump water into their bodies through their pores and extract food from it. Given that sponges live immersed in water and have porous bodies , these organisms filter water to capture food particles, absorb oxygen, and expel wastes. Thus, sponges' porous bodies help them to ' capture food '. The correct answer here is (c) capture food.
