Deferentiat between filter feeders and fluid feeders

These 2 creatures are quite different. One of the differences is that filter feeders filter the water for food particles, while the fluid feeders feed on liquid like blood. Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. Fluid feeders are organisms that feed on the fluid of other organisms. It can refer to: Hematophagy, feeding on blood. Nectarivore, feeding on nectar. Plant sap feeders.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
