1. Biomes Kella Randolph M.Ed .

2. There are seven main biomes.

3. Defining Biomes Biomes  Classification of Earth’s terrestrial ecosystems based on regional climate communities. Major biomes include: tropical rain forest, tropical dry forest, tropical grassland/savanna/ shrubland , desert, temperate grassland, temperate woodland and shrubland , temperate forest, northwestern coniferous forest, boreal forest, tundra.

4. The Major Biomes All biomes have both abiotic and biotic factors. Abiotic factors are non-living such as climate and soil type. Biotic factors are living or formerly living such as plant and animal life.

5. Directions :  For the problem below identify the ecosystem and then list possible abiotic and biotic factors in the ecosystem. Think about it for a moment, then check your answers on the next slide. Ecosystem: Biotic factors Home Abiotic factors

6. Directions :  For the problems below identify the ecosystem and then list possible abiotic and biotic factors in the ecosystem. Ecosystem: Biotic Factors :  man, woman, dog Home Abiotic Factors : carpet, lamp and television

7. Factors that affect global climate l atitude heat area’s proximity to an ocean or mountain range.

8. Defining Biomes The map shows the locations of the major biomes.

9. TROPICAL RAIN FOREST home to more species than all the other biomes combined. get at least 2 meters of rain a year!

11. TROPICAL RAIN FOREST Canopy: Tall trees dense, leafy covering 50 to 80 meters above the forest floor. Understory: below the canopy, shorter trees and vines

12. Many use camouflage to hide from predators or to match their surroundings. Animals that live in the canopy have adaptations for climbing, jumping, and/or flight.

13. TROPICAL DRY FOREST Abiotic Factors warm year-round, with alternating wet and dry seasons. rich soils which are subject to erosion.

14. Biotic Factors – Plant Life Adaptations: extra thick waxy layer on leaves to reduce water loss, or they store water in their tissues. seasonal loss of leaves to survive the dry season. A plant that sheds its leaves during a particular season is called deciduous.

15. Biotic Factors – Animal Life Adaptaions : Emigration of animals in dry season reduce need for water by estivation. Estivation long period of inactivity. similar to hibernation, but typically takes place during a dry season. TROPICAL DRY FOREST Snails in estivation

16. TEMPERATE FORESTS Biotic Factors – Plant Life Deciduous trees drop their leaves and go into a state of dormancy in winter. Conifers have needlelike leaves that minimize water loss in dry winter air. Biotic Factors – Animal Life Some animals hibernate, Others migrate to warmer climates. Animals that do not hibernate or migrate may be camouflaged to escape predation in the winter. Abiotic Factors cold to moderate winters and warm summers. year-round precipitation and fertile soils. The fertile soils are rich in humus material formed from decaying leaves and other organic matter.

17. NORTHWESTERN CONIFEROUS FOREST Abiotic Factors mild temperatures abundant precipitation in fall, winter, and spring. Summers cool &dry. Soils rocky & acidic. Variation in seasonal temperature results in less diversity. Biotic Factors – Plant Life Trees  among the world’s tallest. Biotic Factors – Animal Life Camouflage helps insects and ground-dwelling mammals avoid predation. . Many animals eat a varied diet—an advantage in an environment where vegetation changes seasonally.

18. BOREAL FOREST Also called taiga. Occurs mostly in the northern part of the Northern Hemisphere. The word boreal comes from the Greek word for “north.”

19. BOREAL FOREST Biotic Factors – Plant Life conical shape of conifers sheds snow, wax-covered needlelike leaves prevent excess water loss. dark green color of most conifers absorbs heat energy. Biotic Factors – Animal Life Most have small extremities and extra insulation in the form of fat or downy feathers. Migrate in winter. Abiotic Factors long cold winters and short mild summers. moderate precipitation and high humidity. soil is acidic and nutrient-poor.

20. TUNDRA characterized by permafrost permafrost a layer of permanently frozen subsoil.
