Mollusc taxa Order I Cone snails P Bivalve II Octopuses Q Gastropod III Giant clams R Cephalopod IV Squids
This question requires matching specific mollusc taxa to their correct biological orders. Understanding the defining characteristics of each mollusc group is key to solving this.
Let's analyze each taxon:
Based on the analysis, the correct matching is:
This corresponds to the pairing I-Q; II-R; III-P; IV-R.
Forest patches are embedded within a landscape dominated by crop fields. The crop fields around fragmented forest patches are thought to affect the abundance of different butterfly species to different extents. The graph below shows the pattern of butterfly abundance (means, and error bars representing 95% confidence intervals) of three species, M, N, and O between the forest patches and the crop fields.

Which one of the following options best describes the impact of fragmentation on the three different butterfly species?
