CHAPTER 54
Temperature Ans: The most important factor influencing

species distributions because it affects biological processes.
Guru01 - Stuvia
Wind Ans: Air movement that intensifies ocean waves,
increases heat loss, and influences plant growth.
Expert
Water availability Ans: Determines plant distribution and
influences animal abundance.
Light Ans: Essential for photosynthesis; decreases with water
depth, limiting plant growth.
Salinity Ans: Affects water balance in organisms; freshwater
and marine species require different osmotic adaptations.
pH Ans: Influences decomposition, nutrient availability, and
survival of aquatic and terrestrial species.
Climate Ans: Long-term average weather patterns in a region.
Weather Ans: Short-term atmospheric conditions.
Solar radiation variation Ans: Causes latitudinal differences in
climate; sunlight is more concentrated near the equator.
, 2
Hadley cell Ans: Pattern of atmospheric circulation where
warm equatorial air rises and cools, producing rain and trade
winds.
Adiabatic cooling Ans: Cooling of rising air as pressure
decreases (≈10°C per 1000 m increase).
Rain shadow effect Ans: Mountains block moist air, creating
dry conditions on the leeward side.

Biome Ans: Large ecological region with characteristic climate,
flora, and fauna.
Guru01 - Stuvia
Tundra Ans: Cold, low precipitation biome with permafrost.
Expert
Taiga (Boreal forest) Ans: Coniferous forest biome with long
winters and short summers.
Temperate deciduous forest Ans: Biome with moderate climate
and leaf-shedding trees.
Temperate grassland Ans: Biome with rich soil and seasonal
drought; dominated by grasses.
Hot desert Ans: Very low precipitation and high temperatures;
sparse vegetation.
Cold desert Ans: Low precipitation and cold temperatures;
sparse plant life.
Tropical rain forest Ans: Warm, wet biome with the highest
species diversity.
Tropical deciduous forest Ans: Seasonal rainfall; trees shed
leaves during the dry season.
, 3
Temperate rainforest Ans: Cool coastal biome with high
rainfall and large evergreens.
Mountain zones Ans: Elevational gradient creates distinct
climates and biomes.
Intertidal zone Ans: Area between high and low tide;
organisms face desiccation and wave forces.
Coral reefs Ans: Warm, shallow marine ecosystems with high

biodiversity.
Open ocean Ans: Deep ocean waters with low nutrient levels

and low productivity.
Expert
Lentic habitats Ans: Still freshwater environments such as
lakes and ponds.
Lotic habitats Ans: Flowing freshwater environments such as
rivers and streams.
Thermal stratification Ans: Layering of water temperatures in
lakes.
Upwelling Ans: Movement of nutrient-rich deep water to the
surface, increasing productivity.
Eutrophic lakes Ans: High nutrients, high productivity, often
oxygen-poor.
Oligotrophic lakes Ans: Low nutrients, low productivity,
oxygen-rich.
