|
|
Term
|
Definition
| Organism absorbs nutrients from a host. Specialization= May only be able to survive on one/two species hosts |
|
|
Term
|
Definition
| Chemical secretion of one organism inhibits another |
|
|
Term

Term
| Competitive Exclusion Principle |
|
Definition
| Two species can't share the same niche. The better adapted of the two will win. |
|
|
Term
|
Definition
| Observe directly, such as vegetation and species |

Definition
| Give rise to the pattern- IE resource partitioning. |

Term
|
Definition
| Quantify the patterns and explain the underlying processes that create the patterns |

Term
| Bottom- up control (trophic cascade) |
|
Definition
| Change in nutrient availability affects the entire food chain |
|
|
Term
|
Definition
| excess nutrients enter into a lake or ocean, massive algal bloom |
|
|
Term
| Top-down control (trophic cascade) |
|
Definition
| Abundance of predators causes changes in species abundance of lower levels |
