Arthropod type distribution from leg count data

Steps:

• Tally the total number of arthropods counted from the table.
• Identify and sum the number of each type: insects (6 legs), arachnids (8 legs), crustaceans (10+ legs).
• Calculate percentages: (number of type / total) × 100 for each.
• Compare to choice statements for matches.

Why C is correct:

• Insects total 5 out of 10 arthropods, exactly 50%, matching the statement.

Why the others are wrong:

• A: Insects (5) outnumber crustaceans (2), not equal.
• B: Arachnids are 3 out of 10 (30%), not 25%.
• D: Crustaceans are 2 out of 10 (20%), not 10%.

Final answer: C
