We just finished watching Zootopia and talking about all of the different towns or ecosystems that are present in Zootopia. Each ecosystem has unique characteristics, both in the surroundings and in what plants and animals live there. These are some of the towns that we see in Zootopia: Bunnyburrow Savanna Central Sahara Square Tundratown Little Rodentia Rainforest District The first part of your project is to take at least 2 of these ecosystems and research them. Create some kind of product you would use to teach other people about the ecosystems you have chosen. As part of your project, include the following information: Climate (temperature, rainfall, location/latitude) Characteristics of plants/animals who live there (include at least 2 plants and 2 animals, and at least 2 adaptations for each that allows them to live in the ecosystem) Food chains/webs that exist in the ecosystem (include at least 10 species, including all 4 of your plants and animals from above) The second part of your project is to create an unknown animal that would live in each of your chosen ecosystems. Think about the following and explain why you have chosen each of the answers: What kinds of characteristics would it need to have? What would it look like? Where would it fit into the ecosystem/food web Where would it live? (in a tree, underground, etc.) You can create any kind of product you would like, other than a presentation - think poster, paper, website, etc. You will need to have at least 4 references for this project and a picture of each of your created animals. Be creative here! Remember a big part of this project is focused on research, but there is some creativity as well.

24 Dead zones are areas found in the oceans and some large lakes where there is not enough oxygen to support life. Algae blooms occur when excess nutrients are introduced as pollutants from fertilizers, sewage-treatment plants, and the burning of fossil fuels. When the algae die and undergo decay, bacteria rapidly use the oxygen in the area. Which human activity would most likely result in a decrease in the size and number of dead zones? (1) irrigating fields and lawns to increase runoff into the ocean and rivers (2) building more coal-fired electrical generating plants (3) reducing the use of chemicals on farm fields courses (4) constructing more sewage-treatment plants on the shores of lakes and rivers
