Scientists have discovered a new organism in the rainforest. The organism is multicellular with a nucleus and cell wall and obtains energy through decomposition.

Based on its characteristics and the information in the table above, construct an argument to identify the appropriate clade for its classification.

The organism belongs to Bacteria clade because of the presence of a cell wall and that it is a prokaryote.

The organism belongs to the Eukarya plant clade because of the presence of a cell wall and that it is autotrophic.

The organism belongs to the Eukarya animal clade because of the presence of a nucleus and how it obtains nutrients.

The organism belongs to the Eukarya fungi clade because of the presence of a cell wall and that it is heterotrophic.

Based on this information, which characteristic should be placed at the location of the red X to improve the model?

Wings

Halteres

Social insects

Sucking mouth parts
