1. Ecosystems
living (biotic) and non-living (abiotic) things in biomes are balanced
temperature and precipitation (rain) determine type of ecosystem
Terrestrial biomes = land
Aquatic biomes = water
3
Multiple Choice
4
According to the graph, describe the Tundra (Hot/Cold & Dry/Wet)
Describe the desert. Describe the rainforest.
5
2. Types of Biomes
Grassland
Desert
Tropical rain forest
Temperate rain forest
Temperate deciduous forest
Tundra
Freshwater and saltwater (the largest biome)
6
Multiple Choice
7
Grassland / Savanna biome (trees only found near rivers and stream with rich soil)
8
Desert Biome (very little rain fall, can be very hot or very cold)
9
Grassland/Savanna animals
10
Tropical rain forest biome (found near the equator)
11
Tropical Rainforest Animals
12
Temperate rain forest biome (found along coasts in North America and are cooler than tropical rain forests)
13
Temperate rain forest animals
14
Temperate deciduous forest biome (has changing seasons and changing leaf colors)
15
Temperate deciduous forest animals
16
Tundra biome (near the North Pole, has permafrost layer)
17
Tundra animals
18
Lakes, swamps, rivers, ponds, streams, some wetlands
19
Salt water biome (largest biome)

3. Food chain and Food webs
All living things need energy from food
Food chains link producers (plants) and consumers
decomposers (fungus and bacteria) break down dead organisms
arrows show movement of energy
23
Example of food web: What would happen if you eliminated the hawk?
24
Multiple Choice
In a food chain, producers are...
25
Multiple Select

4. Human Impact
Humans destroy ecosystem by cutting trees, bringing invasive species, and using pesticides
Inspectors stop people from bringing in new plants and animals
Ecologists study the biome community balance (example: Rachel Carson)
27
Ecologist Rachel Carson famous for writing "The Sea Around Us". She studied pesticides and how they can flow into our water and our oceans. This led to the creation of EPA (environmental protection agency)
