What is immigration?
A bison lives in this type of major biome
What is the grassland biome?

What are corals?
A sequence that links species by their feeding relationships
What is a food chain?
When mites move in and live on our eyelashes, but don't hurt us in any way, it is an example of this kind of symbiosis.
What is commensalism?
When a population increases dramatically over a period of time.
What is exponential growth?
This is different from weather, because it refers to the long term pattern of weather conditions rather than day to day change.
What is climate?

What is uniform dispersion?
Winter can last as long as ten months in this biome, and only mosses, low lying plants, and shrubs can survive here.
What is the tundra biome?
This ocean zone contains forty times more biomass than the rest of the ocean.
What is the neritic zone?
Feeds on dead organic matter
