|
Ecological niche |
sum total of how a species interacts with its environment (see chart) |
|
|
Fundamental niche |
full niche before accounting for species interactions (abiotic factors) |
|
|
Realized niche |
niche after accounting for species or biotic interactions (abiotic and biotic factors) |
|
|
Competitive exclusion |
when 2 or more species compete for the same resources, one will eventually exclude the other |
|
|
Resource partioning |
when 2 or more species compete for the same resources, and develop specializations to share resources (Ex: Birds) |
|
|
What are the types of interactions? |
-competition -predation -herbivory -parasitism -amensalism -commensalism -mutualism (see ppt) |
|
|
Food chain |
linear series of feeding relationships |
|
|
What are the 4 types of consumers/producers? |
1. primary producers 2. primary consumers 3. secondary consumer 4. terchiary consumer |
|
|
Food web |
visual map of energy flow in a community (see notebook) |
|
|
How much energy is lost at each level of the food web? |
90% |
|
|
Keystone species |
species that has an outsized influence on its community (often a predator) |
|
|
Modifier |
changes the physical structure of the habitat (Ex: beavers making dams) |
|
|
Mutualist |
species that need each other for survival (Ex: coral reefs and fish) |
|
|
Host |
species that provides habitat |
|
|
Predator |
often a keystone species because without them, the primary producer/consumer reverse energy levels |
