True. This is because they form the lowest parts of the food chain. These invertebrates at young stages are generally exposed to the harsh environments around them. Being organisms that have not developed their mechanisms for protection these invertebrates will be subject to bigger animals and will serve as an easy prey. These invertebrates can be easy prey to larger organisms like birds and frogs, that mostly feed on insects and soft organisms. The saying, "survival of the fittest," is always true when it comes to the ecosystem.

Answer:
The correct option is <em>A) suspension feeder</em>
Explanation:
In biological terms, suspension feeder can be described as an organism which has the ability to feed on the organic matter present in water. The comb jellies have mucus or adhesives on their tentacles which makes them better adapted to engulf food. The mucus or adhesives stick the organic particles from the water to the tentacles and other body parts of the comb jellies. The comb jellies then engulf these particles.
