Bill Moyers Reports: Earth on Edge - Ecosystems Ecosystems are communities of interacting organisms and the physical environment in which they live. They are the combination and interaction of the plants, animals, minerals, and people in any given area of the Earth. A small bog, a single sand dune, or a tiny patch of forest is an ecosystem. In our heavily industrialized societies, work, religious expression, and recreation often take place in urban areas. It is our very reliance on ecosystems that is threatening them. For comprehensive data about the world's ecosystems, visit EarthTrends at www.earthtrends.wri.org/. Take our Interactive Quiz to see how much you know about ecosystems, then check out our Get Involved section to learn about ways you can make a positive difference in your home, your community, and your world.
Fitting Algae Into the Food Web The food web you created in the food web game was one that is found in the Antarctic. As you might imagine, a food web in the tropics looks very different from the one you created. Environmental conditions (temperature, light, nutrients) are different in the two areas, so it would make sense that the organisms that live in those areas might be different also. Divide into groups to create your own food web games. 1) The west coast of South Africa - This is an area often associated with phytoplankton blooms.

Earth Floor: Biomes There are many different kinds of plants and animals on the Earth, but only certain kinds are naturally found at any particular place. (We are not counting zoos here!) For example, cacti are found in the desert, polar bears are found in the Arctic, and elephants are found in central Africa and India. So, why don't people living in south Texas have to be on the lookout for snow leopards, or why don't kids in Minnesota have to worry about finding giant boa constrictors in their back yards? These average weather conditions, such as the range of temperature and rainfall that typically occur in a particular location like Minnesota, are called the climate of that location. Plants and animals don't live in isolation, but they live together with other plants and animals in an interdependent group called an ecological community. A distinct ecological community of plants and animals living together in a particular climate is called a "biome." Next

An ecosystem is a group of plants, animals, and other living things that live in the same surroundings. BiOmEs A biome is a large area with similar microorganisms.Each of these large communities contain species that are adapted to its varying conditions of water, heat, and soil. Check it out!

Journey to Planet Earth . Ecosystems We are intimately familiar with ecosystems. They are the woodlands where we live, hunt, cut timber, or hike; the lakes, streams, and rivers we fish, boat, transport our goods on, and tap for water; the rangelands where we graze our cattle; the beaches where we play, and the marine waters we trawl; the farmlands we till; even the urban parks and green spaces we stroll. In effect, every centimeter of the planet is part of an ecosystem. Ecosystems are: They are systems combined of organic and inorganic matter and natural forces that interact and change. When talking about ecosystems, the matter of scale or size is important. A small bog, a single sand dune, or a tiny patch of forest may be viewed as an ecosystem, unique in its mix of species and microclimate — a microenvironment. In World Resources 2000-2001, "ecosystem" refers to an even larger concept — categories of ecosystems. However, the divisions between ecosystems are less important than the linkages between them.
Food Chain & Web Biomes Webquest - Mr. James 5th Grade "Make Me Fit" A WebQuest for 5th Grade Biomes and Adaptations Introduction | Task | Process | Evaluation | Conclusion Introduction to Biomes The world is made up of many different biomes. 1) Tundra 2) Taiga 3) Rain Forest - tropical and temperate 4) Desert 5) Grasslands - tropical and temperate 6) Temperate Deciduous Forest A biome is made of many similar ecosystems. Within each biome, the living organisms have adaptations to help them survive in these sometimes extreme environments. The unique climate and living conditions of each biome create wide variety on our wonderful planet. Task You are an ecologist who discovered a new animal in the Polar biome. Process 1. Blank World Map Biomes of the World 2. 3. 4. 5.

WebQuest 5th Grade Science Introduction You have a new summer job working for a travel agent. You have been hired to create brochures and posters that will persuade travelers to visit a specific geographical biome. Back to top The Task Working in groups of three or four, divide up the task of researching one of the six biomes: Tundra, Taiga, Temperate Deciduous Forest, Tropical Rain Forest, Grasslands and Desert. The Process First, meet with your assigned group and read through the entire webquest. Criteria Brochure Brochure Template Each group member will create a brochure. Name of biome Labelled map illustrating biome location(s) Landforms Animal life Plant life Climate Your brochure must be edited and assembled in a neat, organized manner. Poster Your poster may be drawn and colored or made with cut and pasted pictures, but must include the following: Biome name Landforms Prevailing precipitation obvious Ten animals Ten plants Resources Evaluation & Reflection (See Rubrics) Conclusion Back to Home Page
