Create a dichotomous key to identify specimens A-H, representing a toad, moth, Spirogyra, Ascaris, sea urchin, snail, fern, and bony fish.

Okay, Mr. , let's tackle this next set of questions. Here is a dichotomous key for the specimens A to H: Q1(i) Dichotomous Key: 1. Is the organism a plant or algae (producer)? Yes → Go to 2 No → Go to 3 2. Does the organism have true roots, stems, and leaves (vascular plant)? Yes → G (Fern)* No (filamentous algae) → C (Spirogyra)* 3. Does the organism have a backbone (vertebrate)? Yes → Go to 4 No (invertebrate) → Go to 5 4. Does the organism live primarily in water and have fins and scales? Yes → H (Bony fish)* No (amphibian, lives on land and water, no scales/fins) → A (Toad)* 5. Does the organism have an external shell? Yes → F (Snail)* No → Go to 6 6. Does the organism have radial symmetry and spines? Yes → E (Sea Urchin)* No → Go to 7 7. Does the organism have wings and an exoskeleton (insect)? Yes → B (Moth)* No (worm-like, parasitic) → D (Ascaris)* That's 2 down. 3 left today — send the next one.
