Observe the image and use the information to answer the following question.
As toxins are passed up through the food chain they tend to accumulate. This is known as biomagnification and is represented by the diagram shown above. An example of how these toxins enter the environment is building a golf course along the coastline in Hawaii. During the heavy rain, pesticides used to maintain the grass are carried by runoff from the golf course to the nearby ocean.
Based off the given scenario, which of the following marine organisms from the coral reef ecosystem will contain the most toxins?
Phytoplankton (Primary consumer)
Small bony fish (Secondary consumer)
Whitetip Reef Shark (Tertiary consumer)
Zooplankton (Primary consumer)

The number of pythons found throughout Everglades National Park has increased in recent years. These huge snakes are not native to Florida and are believed to have been released into the wild by pet owners. Wildlife biologists have initiated attempts to capture and remove these pythons. Which statement best explains the biologists' reasons for removing these pythons from the Everglades?
The pythons could upset the territorial boundaries of native organisms.
The pythons could adapt to overcome diseases common to native snakes.
The pythons could prey on native organisms and cause native population to decline.
The pythons could begin to interbreed with native snakes and produce a more successful species.
