The Burmese Python, an invasive species, has been introduced to the Florida Everglades, largely through release by owners who acquired the snakes from exotic pet traders. Though the Everglades are protected, pythons as predators can not be easily controlled. What can be concluded about the effect of the python population on the biodiversity of the Everglades?
A. Since the Everglades are protected, python control is limited under laws that protect species in the Everglades.
B. Since the python population is growing, it will eventually become a native species and will increase biodiversity.
C. Since pythons prey on many species in the Everglades, resources will be more available for surviving species and fewer will be considered endangered.
D. Since pythons have no predators, they are responsible for decreasing mammal population and are a greater threat to biodiversity.

- A particular species of butterfly is capable of surviving and reproducing both in open grasslands and in forested habitats. However, in the forested habitats this butterfly is heavily predated (eaten) by a forest bird species, so the beetle species avoids these areas and is generally found only in grasslands. Which of the following statements are true? Answer choices: A. The butterfly's realized niche includes both grasslands and forested habitats. B. The butterfly's fundamental niche includes only grasslands. C. The butterfly's realized niche includes only grasslands. D. The butterfly's fundamental niche includes both grasslands and forested habitats E. The butterfly and the forest bird species are in competition.arrow_forwardWhich of the following is a consequence of biologicalmagnification?(A) Toxic chemicals in the environment pose greater risk totop-level predators than to primary consumers.(B) Populations of top-level predators are generally smallerthan populations of primary consumers.(C) The biomass of producers in an ecosystem is generallyhigher than the biomass of primary consumers.(D) Only a small portion of the energy captured by producersis transferred to consumers.arrow_forwardAssume that the population of the greater roadrunner in the Guadelope Desert was 250 per hectare at the beginning of 1999.
