.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The condition in which - at ecosystem boundaries - there is greater species diversity and biological density than there is in the heart of ecological communities.

producer
18. When photochemical smog - NOx compounds - VOCs - and ozone combine to form smog with a brownish hue.

19. The process that occurs when two different species in a region compete and the better adapted species wins.
barrels
ecological succession
competitive exclusion
earthquake
20. The process of burning.
fossil fuel
second growth forests
Infection
combustion
21. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev
logistic population growth
La Nina
tropical storm
composting
22. The area or environment where an organism or ecological community normally lives or occurs.
primary treatment
silt

point source pollution
nitrification
deforestation
27. Creating flat platforms in the hillside that provide a level planting surface - which reduces soil runoff from the slope.
