Barrons AP Environmental Science

plants  from

environmental   stress

easily  come    back.

Seed    dispersal Widespread. Limited   in  range.

Species diversity Limited. High.

Stability   of  ecosystem Since diversity   is

limited,    ecosystem   is

subject to  instability.

Due to  high    diversity,

ecosystem   can

withstand   stress.

MULTIPLE-CHOICE QUESTIONS

For Questions 1–3, choose from the following items:

(A) Tropical    rainforest

(B) Temperate   deciduous   forest

(C) Savanna

(D) Taiga

(E) Tundra

1. Forests of cold climates of high latitudes and high altitudes.


2. Warm year-round; prolonged dry seasons; scattered trees.


3. Low biodiversity due to lots of shade, which limits food for herbivores.
   Major resource for timber.


4. The annual productivity of any ecosystem is greater than the annual
   increase in biomass of the herbivores in the ecosystem because (A) plants
   convert energy input into biomass more efficiently than animals
   (B) there are always more animals than plants in any ecosystem
   (C) plants have a greater longevity than animals
   (D) during each energy transformation, some energy is lost
   (E) animals convert energy input into biomass more efficiently than plants
   do


5. Net primary productivity per square meter is highest in which biome listed
   below?
