3. ANSWER
PART(A):
1. Describe the process of succession. How does primary succession differ from
secondary succession?
Answer 2:
Process of succession there are two kinds of succession are primary and secondary
succession. Both of them create a continually changing mix of species within
communities as disturbances of different intensities, size, and frequencies alter the
landscape. -Primary succession it often take long time, since there is no soil and few
readily available nutrients for growth. -secondary succession is much more commonly
observed and generally proceeds more rapidly, because it begins with the destruction
it occurs when an existing community is destroyed.
2. How does a climax community differ from a successional community?
Answer 2:
A climax community is relatively stable, long-lasting, complex and interrelated group
of many different organisms. A successional community is a stage in the successional
process.
3. List three characteristics typical of each of the following biomes tropical rainforest,
desert, tundra, taiga, savanna, Mediterranean shrublands, tropical dry forest,
grassland, and temperate deciduous forest.
Answer 3:
List two abiotic characteristics typical of each of the following biomes: tropical
rainforest, desert, tundra, taiga, savanna, Mediterranean shrublands, tropical dry
forest, temperate grassland, temperate rainforest, and temperate deciduous forest.
TROPICAL RAINFOREST high rainfall, no frost
DESERT: low rainfall, low evaporation.
TUNDRA: permafrost, low rainfall.
TAIGA: soil freezes in winter.
SAVANNA : two rainy seasons, two dry seasons. MEDITERRANEAN
SHRUBLANDS:dry summer, wet winter. TROPICAL DRY FOREST: monsoon
climate, extensive dry periods.
TEMPERATE GRASSLANDS : low rainfall, few trees.
TEMPERATE RAINFOREST : high rainfall, slow evaporation.
TEMPERATE DECIDUOUS FOREST: evenly distributed rainfall seasons.
PART(B):
4. What two primary factors determine the kind of terrestrial biome that will develop in
an area?
Answer 4:

4. two primary factors determine the kind of terrestrial biome that will develop in an
area:
- Terrestrial primary succession: The kind of substrate (rock, sand, clay) will
greatly affect the kind of soil that will develop. The kinds of spores, seeds, or
other reproductive structures will determine the species available to colonize the
area.
- Aquatic primary succession: All aquatic ecosystems receive a continuous input of
soil particles and organic matter from surrounding land.
5. How does height above sea level affect the kind of biome present?
Answer 5:
As altitude increases, the average temperature decreases. The change in biomes from
sea level to mountain is similar to the change from equator to the North Pole.
