Hey AUDREY, good to see you again. Here are the answers to your questions: 1) a) Your answer to this question should be written in your answer book in columns as shown below: | SPECIMEN | i (Phylum) | ii (Class) | iii (Scientific or Common Name) | | :------- | :---------------- | :----------------- | :------------------------------ | | A | Chordata | Amphibia | Tadpole | | B | Chordata | Amphibia | Toad | | C | Pteridophyta | Filicopsida | Fern Plant | | D | Coniferophyta | Pinopsida | Cypress | | E | Echinodermata | Asteroidea | Starfish | | F | Chlorophyta | Zygnematophyceae | Spirogyra | | G | Annelida | Oligochaeta | Earthworm | | H | Angiospermae | Dicotyledoneae | Hibiscus | 1) b) Specimen A (Tadpole) is adapted to its aquatic environment by: • Having gills for breathing dissolved oxygen in water. • Possessing a tail for propulsion and swimming. • Having a streamlined body to reduce drag while moving through water. • Feeding on algae using a herbivorous mouthpart adapted for scraping. 1) c) i) Organisms that live in a land habitat from specimens A-H are: B (Toad) C (Fern Plant) D (Cypress) G (Earthworm) H (Hibiscus) ii) Ecological relationships that exist among them: • Competition: Fern (C), Cypress (D), and Hibiscus (H) compete for resources like sunlight, water, and soil nutrients. • Predation: The Toad (B) preys on the Earthworm (G). • Decomposition/Detritivory: The Earthworm (G) feeds on decaying organic matter from plants (C, D, H), contributing to nutrient cycling in the soil. 2) a) i) Functions of four external features of specimen B (Toad) which adapt it to life in its habitat: 1. Warty, dry skin: Reduces water loss, helping the toad survive in terrestrial environments, and provides camouflage. It also contains glands that secrete toxins for defense. 2. Strong, muscular hind limbs: Adapted for hopping and jumping, allowing rapid movement on land to catch prey or escape predators. 3. Bulging eyes: Positioned on top of the head, providing a wide field of vision to detect prey and predators effectively. 4. Tympanum (eardrum): Detects sound vibrations, which is important for communication and sensing environmental changes. Send me the next one 📸
