| savanna |
one of the sub-categories of the grassland biome characterized by a wet and dry season with moderate to significant tree growth but where the trees are too sparse to form a canopy |
| rainforest |
a biome characterized by dense tree growth with a thick, multilayered canopy, high amounts of precipitation, and an average temperature of 77 degrees Fahrenheit that doesn't vary more than about 5 degrees all year |
| precipitation |

| competition |
the struggle between the organisms of an ecosystem to obtain the resources needed for survival |

| adaptation |
