Slide 28 / 40 28 The photic zone of the Ocean Extends to the bottom of the Ocean Extends to a depth of about 200 meters Is deep, cold, and permanently dark Is where chemosynthetic bacteria are the only producers
Slide 29 / 40 29 Ponds and lakes are examples of Flowing-water ecosystems Wetlands Standing-water ecosystems Estuaries
Slide 30 / 40 30 Which statement is a valid inference if the human population continues to grow at current rates? Future ecosystems will be distressed and many animal habitats will be destroyed. Global warming will decrease as a result of lower demand for fossil fuels. Over one hundred years after resources are used up the human population will level off. The human population can continue to grow at this rate indefinitely.
Slide 31 / 40 31 Fertilizer runoff into a lake results in eath of algae and other aquatic plants Toxic levels of carbon dioxide entering the water lgal bloom Increased levels of dissolved oxygen
Slide 32 / 40 32 iological magnification refers to The higher concentrations of toxins in the tissues of higher order consumers exposed to toxic waste. The higher concentrations of toxins in the tissues of primary producers exposed to toxic waste. The intensification of the effects of pollution in an ecosystem. Increased levels of carbon dioxide in the Earth s atmosphere.
Slide 33 / 40 33 Rabbits introduced into ustralia have become a serious pest. Rabbit populations have grown so rapidly they have displaced other native species of herbivores.

There are few native predators of rabbits in ustralia. dditional rabbit species have been introduced. There is an increase in rabbit competitors.
Slide 34 / 40 34 Why are fossil fuels nonrenewable? They require hundreds of millions of years to form. Their ecosystems change forever when they are burned. They are converted to carbon dioxide when they are burned. They exist in very small supply.
