Ecology Flashcards
Ecology
The study of interactions that take place among organisms and their environment.
Organism-
One individual that belongs to a certain species.
Population-
All the organisms that belong to the same species living in a community.
Community-
All the populations of different species that live in an ecosystem.
Ecosystem-
All the living organisms that live in an area and the nonliving features of their environment
Climax community:
Stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such a fire, volcano, or glacier.
A final stable community, (after either primary (no soil) or secondary succession-soil present)
Abiotic-
the non-living physical features of the environment, including air, water,sunlight, soil (rocks), temperature, and climate. The pre-fix A means not (living).
- Biotic-
features of the environment that are alive or were once alive. The prefix bio means life.
9.Succession
A natural, gradual change in the type of species that live in an area. Succession can be primary or secondary.
- Climate-
Average weather conditions of an area over time, including wind, temperature, and rainfall or other types of precipitation such as snow or sleet.
Temperate
Deciduous Forest-WE LIVE IN THIS BIOME! We usually have 4 distinct seasons with climax communities of deciduous trees (leaves fall off the branches).
Secondary succession-
A process started by an event such as a fire, glacial movement, volcano erupting, hurricane, ect, which reduces an already established ecosystem to a smaller population of species.
Primary Succession-
A process in which there is uninhabited (no one lives there) barren, no soil, habitat or that occurs where there is no habitat or vegetation.
Pioneer species-
a group of hardy organisms, such as lichens, found in the primary stage of succession and that begin an area’s soil building process.
Limiting
Factors-Anything that restricts the size of the population, including living and nonliving features of an ecosystem, such as predators or drought.
