I, III, and IV D. only Organism Interactions & Population Dynamics A rodent population in a forest ecosystem contains every member of that species. These 3. rodents eat a variety of plants and live in hardwood trees. Their population growth is limited by the amount of space they have available. Human construction in the area is steadily reducing the habitat of the rodent species. Which of the following will most likely occur if the species' habitat continues to be destroyed? The limiting factor of the population will A. change. The species will experience population B. growth. The population will use less resources and stay the same C. size. The species will eventually become D. extinct. Environmental Change 4. The zebra mussel is a non-native species of freshwater mussel that has firmly established populations throughout the Great Lakes. It is originally from southern Russia. Zebra mussels breed quickly and can attach to any hard surface. Their shells can attach to each other in layers that clog pipes and waterways. They can also kill native mussels by attaching to their shells. However, zebra mussels are also very good at filtering the water. Many lakes infested with zebra mussels are cleaner. Which statement about non-native species is supported by the story about zebra mussels? The positive impact of non-native species always outweighs the A. negative. Non-native species can have both positive and negative B. effects.
