🗑
Community   All the populations of different species that live in an ecosystem.  
🗑
Predator   Consumers that capture and eat other consumers.  
🗑
Prey   The organism that is captured by the predator  
🗑
Biotic   features of the environment that are alive or were once alive. The prefix bio means life.  
🗑
Ecosystem   All the living organisms that live in an area and the nonliving features of their Environment  
🗑
Limiting Factors   -Anything that restricts the size of the population, including living and nonliving features of an ecosystem, such as predators or drought.  
🗑
Abiotic   the non-living physical features of the environment, including air, water,sunlight, soil (rocks), temperature, and climate. The prefix A means not (living).

Ecological Succession   Ecological Succession is where a ecosystem changes over time. Sometimes this can be for hundreds of years. The species become more diverse and mature, over time.  
🗑
Primary succession   A type of ecological succession in which no soil is present. Causes: glacier retreating, lava from a volcano erupting, and sand dunes  
🗑
Secondary succession   A type of ecological succession in which soil is present. Examples: Disturbances such as human activities, flooding, fire (SSS)  
🗑
Biome   Large geographical area that has similar climates and ecosystems  
🗑
Pioneer species   the first organisms to move into an ecosystem (e.g. lichens/mosses)
