1 Biome Identification and Biodiversity

2 What Biome am I? Located near the equator Over 200 cm rain each year
Warm temperatures, lots of sunlight Lots of vegetation of plants and animals Biotic factors include large trees that form canopies, parrots, many insects, leopards, etc Poor soil quality Temperature, rain, soil quality and amount of sunlight are biotic or abiotic factors? Vegetation, and animal diversity is biotic or abiotic factor?


4 Tropical Rainforest Typically found near the equator
Receives more than 200 cm of rain annually Temperatures typically fall between 20oC and 25oC for the entire year As many as 50% of all the world’s animal species may be found here

5 What Biome am I? Located between poles and equator
Very few trees with lots of grasses Most fertile soil of all biomes Temperatures between degrees C Precipitation between cm Animals include antelope, bison (US Buffalo), prairie dogs, groundhogs


7 Grassland Because of the dry climate, trees are found only near water sources such as streams Usually receives between 50 and 90 cm of rainfall each year Summer temperatures can reach up to 38oC, and winter temperatures can fall to –40oC

8 What Biome am I? Located at the poles Less than 25 cm rain per year
Temps range from degrees C Has a layer of permafrost Animals include migrating birds in summers, polar bears, reindeer


10 Tundra Means treeless or marshy plain
Characterized by permafrost – permanently frozen soil starting as high as a few centimeters below the surface – which severely limits plant growth Winter temperatures average –34oC while summer temperatures usually average below 10oC Low precipitation (15–25 cm per year) but ground is usually wet because of low evaporation

11 What Biome am I? Located near the equator
Less than 25 cm rain per year Poor soil quality Temperatures between -15 to 38 degrees C Plants such as cactuses Animals such as snakes, lizards, rats and scorpions What are the biotic and abiotic factors that make up this biome?


13 Desert Typically found between 25o and 40o latitude
Receives less than 25 cm of rain each year Temperatures typically range between 20oC and 25oC but some extreme deserts can reach temperatures higher than 38oC and lower than –15oC

14 What Biome am I? Located between equator and poles
Forests have many deciduous trees that lose leaves in fall Fertile soil Temperatures range from -40 to 20 degrees C Rainfall between 30 to 90 cm Animals include foxes, bears deer, squirrels


16 Temperate Deciduous Forest
Moderate climate Most trees will lose their leaves in the winter Temperatures range between –40oC and 20oC Averages from 30 to 90 cm of precipitation Well developed understory

17 What Biome am I? Located at the poles Precipitation between 41-61 cm
Temps range from degrees F Acidic soil Trees are mostly conifers Animals are moose, bears, rabbits


19 Temperate Boreal Forest
Also known as Taiga Typically found between 45o and 60o North latitude Cold climate with summer rains Very few reptiles Limited understory Snow is primary form of precipitation (40 to 61 cm annually)

20 What Biome am I? Located near the equator
Lots of grasses with a few trees mixed in Between degrees F About 100 cm average rainfall Animals include giraffes, zebra, lions, crocodiles and elephants


22 Tropical Savanna Grasslands with a few scattered trees
Experience a wet and dry season Hot temperatures Annual rainfall is between 50 and 127 cm More species of grazing mammals than any other biome

23 What Biome am I? Located between poles and equator
Cool winter, hot dry summers Poor nutrient rocky soils Precipitation between cm Temperatures between degrees F Vegetation includes lots of shrubs Animals include coyotes, mountain lions, jackal, jack rabbits


25 Chaparral Found between 32o and 40o latitude on the west coast of continents Receives between 35 and 70 cm of rain, usually in the winter Extremely resistant to drought and weather events

26 Review Why do tropical rain forests, and temperate forests have so much life? Why do deserts and the tundra have so little life?

27 Biosphere All life on earth
Includes all of the ecosystems and biomes that we have talked about

28 Biodiversity The degree of variation in life forms of a given species, ecosystem, or biome. Includes genetic variation within a species or populations of ecosystems

29 Examples of Biodiversity
Tropical rain forest may have 300 species in square meters (hectre) of land A temperate forest in the US may only have 30 species Biodiversity increases towards the equator.

30 Why is Biodiversity important?
All life is interdependent Animals need plants to survive Flowering plants need animals for pollination Plants need decomposers that break down decaying matter into nutrients If one species is lost from an ecosystem it has a cascade effect on the rest of the ecosystem

31 Bees Honeybees are especially important for maintaining biodiversity
Honeybee populations are declining which impacts our food sources Important for pollination of plants around the world

32 Why is Biodiversity important?
Stability A single pest may be able to destroy an entire corn field A single pest is not likely to destroy all plant life in a rainforest Scattered plant or animal life is less likely to be destroyed due to the genetic variation

33 Loss of Biodiversity Loss of a single species can domino effect the entire ecosystem, which can destroy it Species such as frogs are becoming endangered and could become extinct

34 Domino effect Removing sea otters from kelp forest on west coast have shown to disrupt the entire ecosystem

35 Polar Bears Because of global warming Polar Bears are endangered of becoming extinct 
