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.
4. What are rainforests like?
Why four layers? Use s-cool or BBC bitesize or other sites.
Why have the plants come up with these adaptations?
Others adaptations – find others and add photos and annotations
