Need help with B and C please tulu inud greater than X critical value e 6. Animals are often faced with choices or trade-offs in nature. A good Table 10.5 example of this is an idea coined "optimal foraging theory." This theory states that foraging animals will try to maximize their en VISITS TO EACH ergy intake (a benefit, like food or territory), while losing a minimal amount of energy to find a resource (cost) (for more information Quality High Med Low on optimal foraging theory, search the web). Foraging behavior de- Bee A 16 11 10 scribes a particular means by which an animal searches for a food Bee B 13 7 5 resource. In many species of foraging insects, like honey bees in Bee C 12 the Apis genus, individuals are likely to choose or select the same 18 14 Bee D 11 host plant species to find nectar, which is t ed "Roral consta Scientists have suggested that foraging on familiar plant species Bee E 15 12 throughout a lifetime is less costly, and provides a more predictable Bee F 19 15 9 source of food for a bee. Bee G 9 16 To test the optimal foraging theory in honey bees, Dr. brain set Bee H 16 Bee 1 21 14 19 up a lab experiment with three fake flowers-each of which had an unlimited supply of a different quality of nectar (high calorie, low Bee 17 10 7 calorie, and in between); the fake flowers were otherwise exactly t Sum 149 112 114 same. She marked 10 individual bees and allowed them to forage in the lab for two hours. She observed the foraging and recorded the number of visits each flower received from each bee (able 10.5). 200
Explanation / Answer
b. Here, the honey bees will visit the flower with high calorie amount of honey more, then those with medium calorie amount of honey and those with low calorie amount of honey, they will visit the least. According to the foraging behaviour theory, this should be the case. This have been observed in case of most of the bees, only with exceptions in case of two honey bees. So, the hypothesis is true.
c. The wolf should capture the elk, because though in this case the wolf has to spend more amount of energy, but it is also gaining more calories. The difference between the calorie intake and spent is more in this case, than what would be in a human hunting camp.
