Which of the following explains what environmental and physical characteristics of the finches led Darwin to develop his theory?

• A. Darwin concluded that the beaks were different because the finches were not related species on the different islands.

• B. Darwin concluded that the beaks were different because they are attracting various predators that will eat them for energy.

• C. Darwin concluded that the beaks were different because they acquired traits that developed based on the food source.

• D. Darwin concluded that the beaks were different because the food source allowed for survival of the trait that was best and passed on.

• A. The population has reached carrying capacity

• B. The population is declining due to a new predator

• C. The population is increasing because more food became available

• D. The population is remaining constant because the birth rate and death rate are equal

Which of the following correctly describes the impact of an abiotic factor on the population dynamics of an ecosystem?

• A. Organisms that compete for the same resources will keep each other from over populating.

• B. A parasite that invades a host can reproduce and cause a decline in the host species population.

• C. Herbivores will not be able to deplete the plants and other resources in an ecosystem due to predation.

• D. Seasonal variations in temperature and precipitation can cause some of the individuals in a population to die.

A hurricane passes through the Gulf of Mexico and destroys the coastal regions of NW Florida. Which is a likely impact of this event on biodiversity?

• A. Species brought in by the storm surge will displace species native to the coastal wetlands.

• B. Species reliant on coastal wetlands for survival may experience a decline in population due to loss of habitat.

• C. Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity will increase in these areas.

• D. Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the local species, causing a decrease i

A high rise condominium is planned for a barrier island that is on the SW Florida coast. What impact will this have on the coastal ecosystems?

• A. Key species found on the barrier island will move to a new habitat.

• B. Predators will abandon the habitat as humans are the top predator in any ecosystem.

• C. The ecosystem will be destabilized as abiotic resources like available space are reduced.

• D. The coastal ecosystem populations will decline until new species evolve that are adapted to live by new humans.

Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosystem?

• A. There is less energy available in the producers because their tissues are less dense than those at higher trophic levels.

• B. There is more energy available in the second trophic level because less energy is needed for hunting compared to the higher trophic levels.

• C. There is less available energy in the fourth trophic level because of the loss of energy through metabolism in each of the lower trophic levels.

• D. There is more available energy in the birds of prey because they have greater muscle mass for storing energy than organisms in lower trophic levels
