Yоu will be given а scenаriо thаt applies tо the next few questions. Please look at the prompt at the bottom to see what you are to fill in. You are exploring a mangrove forest along a tidal river. The air is humid, roots twist above and below the water, and the mud is littered with crabs and fallen leaves. As you move around, you notice: Two species of hermit crabs near some mangrove roots appear to be battling over a food-rich area. The larger blue hermit crab repeatedly pushes the smaller red hermit crab out of the area. After a short while of many failed attempts to access this food rich area, the red hermit crab moves to another section of the mangrove in search of food. Looking under the water, you notice a shrimp digging a large burrow. In front of the shrimp is a small goby fish. After observing for several minutes, a large snapper fish swims near, the goby instantly alert swims into the burrow, alerting the shrimp who instantly follows into the burrow for safety. Along the muddy edges of the mangrove, you find mudskippers. Healthy mudskippers are brown with blue spots, but you notice several dead mudskippers with small red, worm-like organisms moving on their bodies. Further along the edge, you spot what appears to be a tree branch moving slightly. Upon closer inspection, it is actually a stick insect, perfectly still and blending into its surroundings. As you continue exploring, you think about how all these species interact, survive, and compete in this unique mangrove ecosystem. The two hermit crab species show one species being forced to move due to the other’s dominance. What type of ecological interaction is this? _________. (BE SPECIFIC)
Yоu hаve stumbled оntо Islа Nublаr, and Dr. Alan Grant has tasked you with figuring out how fast the dilophosaurus population will reach its carrying capacity of 30 and take over the island. Your initial assessment finds 17 dilophosaurus on the island. You estimate the intrinsic rate of increase to be 0.7 per month from fossil record (in real life you cannot determine r from fossils, but use your imagination for this question). Dr. Grant wants to know how long you can safely stay on the island before risking a face full of blinding dilophosaurus saliva similar to what happened to Dennis Nedry. Instructions: Determine how long you can stay on the island before the population comes within 3 individuals (~97%) of carrying capacity (how many months before you are within three individuals of carrying capacity). Show your work as that will count for credit. (10 points).
