1. Identify the range of senses involved in communication • Sight (visual communication), Touch (tactile communication), Taste, Hearing (auditory communication), Smell (olfactory communication) 2. Identify the limited range of wavelengths and named parts of the electromagnetic spectrum detected by humans and compare this range with those of THREE other named vertebrates and TWO named invertebrates. Figure 1: the electromagnetic spectrum source: www.ces.fau.edu Vertebrates Human Japanese Dace Fish Rattlesnake Zebra Finch Part of electromagnetic spectrum detected ROYGBV (visible light) detected by light sensitive cells in the eye called rods and cones.

Suggest reasons for the differences in range of electromagnetic radiation detected by humans and other animals. Humans and other animals can detect different ranges of electromagnetic radiation due to their varying functions; this better suits them to their environment. Humans are able to see visible light (ROYGBV) only, as this allows them to distinguish between different objects and foods; ultraviolet and infrared vision is not necessary for their survival. Other animals have adaptive advantages to their environment, for example: • The Rattlesnake is able to detect infrared light via pits under their eyes. This allows them to easily detect their pray when hunting at night, giving them a better chance of finding food. • The honeybee detects ultraviolet light patterns on flowers via the photoreceptors in their eyes, allowing them to distinguish between those with pollen/nectar and those without. • The Japanese Dace Fish is able to detect UV light, assisting in mate selection and detection of prey- hence helping survival as prey is able to be
