Which changes would most likely limit the growth of a plant-eating animal population? Select four options. The number of predators decreases. Steady rainfall increases the number of plants. A spring freeze kills many plants. The number of predators increases. A harmful plant disease spreads through the area. A harmful animal disease spreads among the population.

Select whether each statement refers to a density-dependent or density-independent factor for population growth.When a prey species becomes more common, predators can more easily find it and kill relatively more. This would be a factor that limits population growth.A hurricane would be a factor that would impact population size.A limit to population growth that has greater influence as population size increases such as a parasite that can more easily jump from host to host would be a factor.

Which of the following factors is most likely to decrease the stability of an ecosystem?*2 puntosAn increase in plant biodiversityAn increase in animal biodiversityThe removal of an individual animalRemoval of a species

Under which of the following conditions would an animal population most likely survive the effects of rapid climate change?Responses                The individuals in the population are carnivorous.                The individuals in the population are carnivorous.The females in the population have one or two offspring per litter.The females in the population have one or two offspring per litter.The population has a small geographic range.The population has a small geographic range.               The population is highly mobile.

Read each of the scenarios below. Then, select the option that best represents a scenario illustrating natural selection.A In a population of birds, those with larger beak sizes are better able to crack open tough seeds, providing them with a food source during periods of scarcity. Consequently, the average beak size in the population decreases.B In a population of flowers, those with a particular color variation attract more pollinators and produce more offspring. As a result, the proportion of flowers with that color variation decreases over generations.C In a population of rabbits, those with longer legs are more successful at outrunning predators and are more likely to survive and reproduce. Over time, the average leg length in the population increases.D In a population of fish, those with brighter colors are more easily spotted by predators, leading to higher mortality rates. As a result, the proportion of fish with bright colors increases over time.

Select the correct answer.A population of herbivores is at its carrying capacity for its habitat. Which factor is likely to result in a sudden rise in population that far exceeds the carrying capacity? A. birth of young B. emigration C. immigration D. introduction of a new limiting factor
