1 Atom Molecule Macromolecule Organelle Cell Tissue Organ Organ System Organism Population Community Ecosystem/Biome Biosphere Levels of Organization MATTER LIVING THINGS ECOSYSTEM

2 Organism Population Community Ecosystem Biome

3 An individual living thing. Organism

4 Same type of organisms living together in an area. Population

5 Several different populations living together and interacting with each other. Community

6 Ecosystem A biotic (living) community plus the abiotic (nonliving) components.

13 A BIOME is large region characterized by a specific type of climate and the plants and animals that live there. Tropical Rainforest Desert

14 The BIOSPHERE is a ll the biomes of the world including the abiotic components. http://people.hofstra.edu/geotrans/eng/ch8en/conc8en/envisys. html

15 Trophic level is the position organisms have in the food chain.

16 A FOOD CHAIN is the transfer of energy from one organism to another in an ecosystem in a line.

17 A FOOD WEB is a complex network of interconnected food chains in an ecosystem.

18 Organism Population Community Ecosystem Biome

19 A BIOME is large region characterized by a specific type of climate and the plants and animals that live there. Tropical Rainforest Desert

20 Producers are organisms that produce their own food through photosynthesis.

21 Herbivores

22 Carnivores

23 Scavengers

24 Omnivores

25 Decomposers

26 Sunlight is the main energy source in an ecosystem.

27 Percipitation is rain, sleet, hail, snow, etc.

28 Soils contains the nutrients needed by living things.

31 Ponds, lakes, rivers, streams, puddles, and oceans

32 COMPONENTS OF AN ECOSYSTEM BIOTIC (living parts) ABIOTIC (nonliving parts) Producers (take sunlight and produce food) Sunlight Herbivores (consumers that eat only plants) Precipitation (rain, snow, hail, etc.) Carnivores (consumers that eat only meat) Soil and Rocks Scavengers (consumers that feed on dead things left behind by predators or road kill) Temperature Omnivores (consumers that eat both meat and plants) Minerals (nutrients) Decomposers (break down dead organisms and recycle the nutrients back to the environment) Water (ponds, lakes, rivers, etc.)

35 YEARLY AVERAGE TEMPERATURE & PRECIPITATION

36 Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain.

37 When water saturates the upper surface, bogs and ponds may form, providing moisture for plants.

38 Soil in the Tundra is poor in nutrients. Permafrost is a layer of soil that is frozen year round. Only the top active layer thaws out in summer.

51 There are about 1,700 kinds of plants in the arctic tundra.

52 Arctic Poppy

53 Arctic Dwarf Willows

57 There are two types of TUNDRA: Arctic Tundra Alpine Tundra

58 ARCTIC TUNDRA

59 ALPINE TUNDRA

60 rctic tundra is in the northern hemisphere surrounding the north pole. ainfall and snow combined average is 6 to 10 inches yearly. oldest and driest of all the biomes. he only trees that grow in the tundra are the dwarf willows. ce melts during summer but can’t drain into the soil because it is frozen. he top layer of soil is called the active layer which melts during summer. nder the active layer is the permafrost which is frozen soil year round. ame“tundra”is from the Finnish word tunturia, meaning treeless plain. warf willow trees are only 4 inches tall. verage winter temperature is –30 0 F and summer temp. is 37-54 0 F. overs 20% of the Earth’s surface. eferred to as a cold desert.

74 T he frigid cold and deep snow makes life in the tundra very difficult. Every animal must adapt in order to survive. Some have grown thick fur which turns white in the winter. Others find a place to hibernate during the winter months. T he arctic tundra is at the top of the world -- around the North Pole. Animals are adapted to handle cold winters and to breed and raise young quickly in the very short and cool summers. T emperatures during the arctic winter can dip to -60 F (-51 C)! The average temperature of the warmest month is between 50 F (10 C) and 32 F (0 C). Sometimes as few as 55 days per year have a mean temperature higher than 32 F (0 C). The average annual temperature is only 10 to 20F (-12C to -6C). T he soil is often frozen. Permafrost, or permanent ice, usually exists within a meter of the surface. Water is unavailable during most of the year. A nnual precipitation is very low, usually less than 10 inches (25 centimeters)
