biology chapter 5 Flashcards
(26 cards)
Community
A group of populations of different organisms that live in the same place at the same time
Invasive species
Species that spread rapidly and become the dominant species in the community, causing interference with natural biodiversity
Predation
The process in which one species, the predator, feeds on the prey
Competition
Two species compete for the same limited resource
Parasitism
The relationship in which one organism depends on another for nourishment or for some other benefit will simultaneously doing the most talk
Mutualism
A relationship in which two or more different species benefit from interaction with one another
Niche
The functional role a species play in the community to enhance their survival
Fundamental Niche
The full amount of resources available to a species in absence of competition
Realized niche
Because competitors in the community restrict what resources can be used, species are limited to a realized Niche
Food chains and webs
A conceptual record of feeding relationships and energy flow
Primary consumers
Animals that eat plants, also called herbivores
Secondary consumers
Animals that eat herbivores
Detritivores and decomposers
Eat nonliving organic matter; they recycle nutrients
Foodchain
Simplified linear diagram of who eats whom
Food web
A complex network of who eats whom
Keystone species
A species that has far-reaching impacts to the rest of the ecosystem
Succession
The regular, predictable, and quantifiable sequence of changes that a community undergoes overtime
Primary succession
Follows a disturbance so severe that no vegetation or soil life remains in the community that occupied that site
Pioneer species
The first species to grow and emerge to begin the process of recolonization
Secondary succession
Occurs when a specific event alters a community
Climax community
Remains in place, with little modification, until some disturbance restarts succession
Biome
A major regional complex of similar communities of vegetation
The main factors determining what the vegetation will be like and will in turn determines what animals will inhabit a biome
Temperature and precipitation
What biome do we live in
Temperate deciduous forests
