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.
