Your ecosystem can be large like these or small, like a pond. My ecosystem will be:……………………………..
Your presentation must cover these questions: 1.Where is your ecosystem found? 2.Why is it found there? 3.Is your ecosystem a biome? 4.What is your ecosystem like? (plants, animals, soil, climate (if not covered in 2.) 5.What are the natural or human impacts in your ecosystem? 6.What can be done about them?
To get a good grade: Keep to time limit (3 minutes) Few words on slides Clear images Good choice of images Logical order to slides All 6 questions covered Thorough explanation by you High interest level from audience Eye contact with whole audience Good use of voice (speed, loudness, emphasis)
The tropical rainforest ecosystem Ecosystem means:
1. There is a narrow strip along the very north-west of South America where it joins to Central America 2. The northern most 2/3 of Brazil are rainforest and it extends as far as the Andes to the west. 3. There is a narrow strip along the south-west coast of Brazil. Describing where they are.
World map showing the location of rainforests Say where they are in the world.
2. Why are rainforests where they are? Watch the video clips and then paste in a diagram to show where rainforests are where they are: a) Convectional rainfall
b) Temperature Write a sentence to say why the climate is hot at the Equator
3. Is the rainforest ecosystem a biome? Scientists discuss some general ecosystem types. They call them biomes. A biome is a large area on the Earth's surface that is defined by the types of animals and plants living there. A biome can be partially defined by the local climate patterns. - Tropical Rainforest - Tropical Savanna - Desert - Mediterranean Woodland - Mid-latitude Grassland - Mid-latitude Deciduous Forest - Tundra - Ice Caps Biomes may be ecosystems found on a large scale, and may have smaller ecosystems within them.
