Hint: A filter feeder refers to an animal that feeds by filtering organic matter or microscopic organisms from a stream of water that moves through some portion of its system. Simply put, filter feeding means that the animal or organism opens its mouth and lets in whatever is available while filtering out the unwanted elements. Filter feeders are beneficial to the health of a body of water.
Complete answer:
Sponges are a type of porifera. Sponges feed through a mechanism through which sponges transfer water into their bodies to consume food. Water enters the sponge from tiny holes known as incurrent pores. Bacteria and small particles from the water are eaten up as food, as it passes into the sponge's tubes and chambers.
- Sessile animals are those animals which cannot move from one place to another.
- Terrestrial species are those species that live mostly or entirely on land (for example, cats, ants, and spiders), as opposed to marine animals, which live mostly or entirely in water.
- Active filter feeders are those species whose water is drawn from external or internal filtration organs by rotating their cilia or by contracting their muscles.
- Occasional filter feeding, as the name suggests are organisms that filter feed occasionally.
- Sponges are sessile marine creatures, which means they stick to an underwater surface and stay there.
As a result, the correct answer is 'Sessile'.
Therefore the correct answer is option ‘A’.
Note: Sponges are animals that are a part of the phylum Porifera. They are small creatures with a lot of cells but no mouth, arms, heart, or brain. A sponge is a species that, like most plants, develops in a single location.
