Question
Chapter 60, Problem 8TY
Summary Introduction
Introduction: The variation and the variety in both flora and fauna population of habitat are called biodiversity. High biodiversity richness is an important factor responsible for the proper functioning of the ecosystem. Human interference and expansion have been the cause for the destruction of such biodiversity-rich areas and the extinction of the species living in these habitats.

- All of the statements are correct regarding ecological succession EXCEPT Select one: a. there is less competition earlier in the succession process b. it is a random process c. initial pioneer species are plants d. species diversity increases as succession proceedsarrow_forwardThe 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.arrow_forwardThe graph above is from a paper by Dave Tilman published in 1994.
