Population
A group of individuals of the same species living in the same area.
Community
A group of populations living in the same area.
Ecosystem
The interrelationships between the organisms in a community and their physical environment.
Biosphere
It includes all the regions of the earth that contain living things.
Habitat
The type of place where it usually lives. It includes the other organisms that live there as well as
the physical and chemical characteristics of the environment.
Carrying Capacity
The maximum number of individuals of a population that can be sustained by a particular
habitat.
Limiting Factors
Elements that prevent a population from attaining its biotic potential.
Abiotic Factors
factors are the non-living parts of an organism's habitat.
Soil, Water, Air, Temperature, and Sunlight.
Biotic Factors
The living parts of an ecosystem.
Usually include: producer, consumers, decomposers, and human influence.
Mutualism
A relationship between two species in which both species benefit.
Primary Producers
They convert solar energy into a form that can be used by the rest of the community. Aka
autotrophs.
Heterotrophs
Species that obtain energy by breaking apart organic compounds that have been assembled by
other organisms. (Herbivores)
Primary Consumers
Heterotrophs that dine on primary producers... aka herbivores.
Secondary Consumers
Primary carnivores... those that consume herbivores.
Tertiary Consumers
Those that consume secondary consumers
Trophic Levels
The feeding positions: primary producers and primary, secondary, and tertiary consumers. A
group of organisms united by obtaining their energy from the same part of the food web.
Omnivores
They feed on both plants and animals. (feed from multiple trophic levels.)
Decomposers
Feed on waste products or dead bodies of organisms... Largely responsible for the recycling of
materials within ecosystems. They break down organic matter into inorganic components that
primary producers can absorb.
commensalism
A symbiotic relationship in which one organism benefits and the other is unaffected
Parasitism
A symbiotic relationship in which one organism benefits and the other is harmed
Herbivores
Consumers that eat only plants
Carnivores
Consumers that eat only animals
transpiration
evaporation of water from a plant
