biome miniquiz Flashcards
tropical rain forest overview
- have more species than all other biomes combined
- get at least 2 meters of rain a year
- tall trees form dense leafy cover called canopy
- canopy shades layer of shorter trees and vines called understory
abiotic factors tropical rainforest
- hot and wet year round
- thin, nutrient-poor soils subject to erosion
tropical rain forest plants/animals
- understory plants use large leaves to compete for limited light
- animals are active all year, use camouflage to hide from predators
tropical dry forest overview
-grow in areas where rainy seasons alternate with dry seasons
tropical dry forest abiotic factors
-warm year-round, usually period of rain is followed by long period of drought
tropical dry forest plant/animal
- some plants lose leaves to survive dry season (deciduous)
- many animals reduce need for water during dry season by entering long periods of inactivity (estivation)
tropical grassland/savanna/shrubland overview
- receives more seasonal rainfall than deserts but less than tropical dry forests
- mostly grass with isolated trees and small groves of trees and shrubs
tropical grassland abiotic factors
- warm
- seasonal rainfall
- compact soils
- fires set by lightening
tropical grassland plant/animal
- plant adaptations include waxy leaf covers and seasonal leaf loss
- many animals migrate during dry season to find water
- some small animals burrow and remain inactive during dry season
desert
- have less than 25 centimeters of precipitation annually
- many undergo extreme daily temperature changes
desert abiotic factors
- low precipitation
- variable temperatures
desert plant/animal
- plants store water in tissues
- minimize leaf surface area to cut down on water losses
- many desert animals get water from food they eat
- many are active at night to avoid hottest parts of day
temperate grassland overview
- mostly grasses, maintained by periodic fires and heavy grazing
- soils fertile and ideal for growing crops
- most converted for agriculture
temperate grassland abiotic factors
- warm to hot summers
- cold winters
- moderate seasonal precipitation
- occasional fires
temperate grassland plant/animal
- plants resistant to grazing and fire
- predation threat for smaller animals bc of open environment
- camouflage and burrowing are common adaptations
