| rain forest | The bome with the greatest species diversity |
| Spines of desert plants | provided protection |
| Low biodiversity | This is why tundra ecosystems are fragile. |
| nearness to the equator | This causes stable year round temperatures for tropical zones. |
| Decomposers | Warm temperatures & humidility help these break down organic matter |
| rain forest | The biome that is the most productive and diverse on Earth. |
| Bison & other grazing animals | These act as a lawn mower on the grasslands. |
| Long, thin, wax-coated needs of conifers | These help the trees conserve water |
| pine needles | These insulate the ground of coniferous forests |
| herbs, lichens & mosses | what you expect to see near the top of a mountain with year-round ice & snow |
| Animals of the taiga | These have the ability to change color to avoid predators |
| Grassland biomes | These are susceptible to fires, low to moderate rainfall with few to no trees. |
| Tropical rain forests | These help regulate world climate & play roles in nitrogen, oxygen, & carbon cycles |
| tundra | Coldest biome |
