Kinds of Ecosystems Chapter 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 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
