Succession- a process of community change
Primary succession- succession that starts with NO soil
Example:lava flow
Secondary succession- succession that starts with soil
Example: forest fire
Pioneer species-First Species to colonate an area during primary succession
Climax community- a community that is experiencing little or no succession
Limiting factors- anything that can limit the size or distribution of a population
Density Dependent Limiting Factor- limiting factor that has an effect because of the size of the population. Examples: predators, disease
Density Independent Limiting Factor- regardless of population size everyone dies. examples: Natural Disaster\
Food Chain- Simple representation of energy flow
(The arrows represent energy flow0
Food Web- complex repressentation of energy flow
Homeostasis- Internal Balance
Producer (autotroph)- produce own nutrience. Ex: plants
Consumer (heterotroph)- requires other organisms for nutrients. Ex:animals
-6 Types of heterotrophs
-Carnivores- Meat eaters. Ex: Lion
-Herbivores- Plant eaters. Ex: Cow
-Omnivores- Both meat and plant eaters. Ex: Humans
-Scavenger-Eats dead stuff. Ex: Vulture
-Decomposer-Absorbs nutrients. Ex: Fungi
-Parasite- Needs a Host. Ex. Viruses
Mortality Rate- Death Rate
Fecundity Rate- Birth rate
