Is a sponges secondary consumer

Answer 1

No, sponges are not considered secondary consumers; they are primarily classified as filter feeders and belong to the category of primary producers. They obtain their nutrients by filtering small particles, such as bacteria and organic debris, from the water. As such, they play a crucial role in the aquatic ecosystem by recycling nutrients, rather than consuming other organisms directly. Secondary consumers, on the other hand, typically feed on primary consumers in the food chain.
