Kinds of EcosystemsChapter 4
Quote• “In all things of Nature there is something of the marvelous”
• Write down an interesting fact about nature, then we will discuss what types of ecosystems those animals live in.
Ecolog• Answer the Ecolog Questions on page 78.
Save the Rainforests• Burning match – in the time that it takes to burn a single
match, 97 acres of Rainforest are burned (roughly the size of a football field)
Terms• Biome – areas that have distinctive climates and organisms• Climate – refers to the weather conditions in an area over a
long period of time
Chapter 4 Project• You are going to research a specific type of ecosystem and
become an expert on it
• You are then going to teach it to the rest of the class
• You need to have a lesson plan which includes: objectives, the actual lesson, a handout (assignment), and a visual aid (power point, etc.).
Types of Ecosystems• Tropical Rain forests• Temperate Rain forests• Deciduous forests• Taiga• Savanna• Grasslands• Chaparral• Desert• Tundra• Lakes and Ponds• Wetlands• Rivers• Ocean• Estuary• Coral Reefs• Polar
Tropical Rain Forests• Tropical Rain forests – occur in a belt around the earth near
the equator• Humid, Warm, over 100 inches of rain a year lots of sun
Terms• Canopy – trees more than 100 feet tall, absorb 95% of the
sunlight
Adaptations• Look at page 82, what characteristics do the bat and flower
have that allows them to thrive in the rainforest
Save the Rainforests• Research 5 things that are products that come from
rainforests. Explain how they are manufactured and if the rainforests disappear where is an alternative source for this.
• Woods, houseplants, spices, fruits, vegetables, other foods, fibers, gums, resins, pharmaceuticals, and oils are all categories to get you started.
• Include pictures of your products.
Adaptations• Thumb Lab – you are going to have your thumbs taped so they
cannot be used• You will need to perform a series of tasks then write about
each discussing the difficulties without thumbs. • Then you will write a paragraph explaining how primates are
adapted to living in the rainforest
Limiting Factors• Limiting Factor Principle – too much or too little of an abiotic
factor can limit or prevent the growth of a population
• What is the limiting factor in the tropical rain forest ecosystem?
Temperate Rain Forests• Temperate Rain Forests – the Pacific Northwest is North
America’s only example• Massive trees, mosses, ferns, and lichens use the abundant
moisture and thrive
Case Study• Read the Case Study found on pages 84-85 and answer the
questions
Temperate Deciduous Forests• Temperate Deciduous Forests – forests found in this part of
the country (broadleaf forest)
Taiga• Taiga (boreal forests) – northern coniferous forests with
extreme cold temperatures
Section Review• Do the section review on page 89
Grasses• How is the grass in these pans similar to a grassland biome?
• How are they different?
Savanna• Savanna – found in the tropics near the equator, but receive
too little rain for many trees to grow
Temperate Grasslands• Temperate Grasslands: Prairies, Steppes, Pampas• Found in the interiors of continents where there is too little
rainfall for trees to grow• Mountains play a crucial role (rain shadow)
Grazers• Why would grazers native to a grassland have less of an impact
on the area than introduced grazers?
Chaparral• Chaparral – found with Mediterranean climates, dry, hot
summers, mild, wet winters
Deserts• Deserts – areas that receive less than 10 inches of rain per
year• Drought resistance – survival strategy of plants, many die and
drop their seeds for the next rainfall• Estivating – basically hibernating during the summer
Questions• What affects to ATV’s have on a desert ecosystem?
• Do you think that people should be allowed to seek out recreational opportunities where ever they want?
Tundra• Tundra – biome without tall trees, north of the arctic circle• Permafrost – permanently frozen soil
Imaginary Organism• You are going to create an organism that could exist in a
Tundra Biome.
• You need to include it’s adaptations that allow it to survive as well as a drawing of the organism.
• Write a paragraph explaining its existence
Section Review• Answer the section review questions on page 99
Pond Water• Pond Water Comparison• These two jars are from the same source• What differences do you see?• What could have caused these differences?• Do you think that this is an unhealthy situation?
Lakes and Ponds• Littoral Zone – nutrient rich area of lakes and ponds• Benthic Zone – bottom of the body of water inhabited by
decomposers, insect larvae and clams• Why is Great Salt Lake salty?
Wetlands• Wetlands – areas of land that are covered with water for at
least part of the year • Marshes – have non-woody plants• Swamps – have woody plants
Rivers• Rivers – originate from snowmelt in the mountains or from a
spring
Fish• Fishing Trip – We are going to research types of fish caught in
the Zumbro• Research the type of fish that you could expect to catch and
the type of bait you will need
Section Review• Do the section review on page 104
Huge Animals• What is the largest animal on Earth?• It weighs over 242,000 lbs• Its larger than any dinosaur ever found• Why couldn’t an animal that large live on land?• What are some other organisms that exist with this animal?
Estuary• Estuary – freshwater from rivers mixes with salt water from
oceans
Coral Reefs• Coral Reefs – limestone islands in the sea that are built by
coral animals called polyps
Ocean• The Ocean – vast body of water
Polar Caps• Polar Ecosystems – ice covered polar caps• Arctic – shallow frozen sea• Antarctic – large landmass surrounded by frozen sea
Section Review• Do the section review on page 112 and re-answer your ecolog
questions
Chapter Review• Do the chapter review on pages 114-115 questions 1-21 and
read pages 118-119
Lab• Local Biome Lab
