Population Ecology Questions Answer the questions briefly and concisely. 1. Choose a population of organisms and its habitat in Puerto Rico or some region of the world. a. Describe how the biotic potential affects its population growth. Mention at least three factors. b. Is this population having environmental resistance? Explain c. If there is environmental resistance, list the density-dependent or density- independent factors. 2. Mention three differences between exponential and logistic growth. 3. What is the current human population growth curve in Puerto Rico and how does it compare with world human population growth?

Population size of commander butterflies Population| Original size| Final size 1 2436 2873 2 2185. 2649 Which of the following concepts would best compare the change in population size of the two populations?

When population density reaches the carrying capacity of the environment, the death rate in the population becomes A.) less than the birth rate B.) equal to the birth rate C.) more than the emigration rate D.) more than the immigration rate
Mimicry occured in nature as species tahe advantageous characteristics from other species to help them survive. As humans, we have also taken this idea of biomimicry and used nature as a design inspiration to sustainably solve human problems. some examples include: whale fins as wind turbines, shark skin materials for marine vessels and swimwear, burrs stick to animals and velcro, water collecting beetles and environmental application. Questions 1. Identify a real world challenge and think about potential designs to solve or help with this challenge. 2. research nature's models - what biomimicry can we see in nature for this challenge? 3. describe a model that could aid in the real world issue and have potential sustainable application.
F5 Which option below most likely describes the nature of the pollutant and the trophic levels of each of the three species? 5 Pollutant Concentration (ng/g) 30- O Black squares represent a primary producer, red triangles an herbivore, and blue circles a predator. The pollutant is biomagnifying in the community. Blue circles represent a primary producer, black squares an herbivore, and red triangles a predator. The pollutant is biomagnifying in the community. Red triangles represent a primary producer, blue circles an herbivore, and black squares a predator. The pollutant is causing eutrophication of the lake. Red triangles represent a primary producer, black squares an herbivore, and blue circles a predator. The pollutant is neither biomagnifying nor causing eutrophication.
