It is the study of the interactions among living things and between living things and its surroundings.
It is a group of different species that live together in one area.
All of the organisms as well as the climate, soil, water, rocks and other non-living things in a given area.
It is a major regional or global community of organisms.
They are living things such as plants, animals, fungi and bacteria.
They are non-living things such as moisture, temperature, wind, sunlight and soil.
The assortment or variety of living things in an ecosystem.
A species that has an unusually large effect on its ecosystem.
These are organisms that make their own food.
These are another name for producers.
They are organisms that get their energy by eating other living or once living resources.
These are another name for consumers.
The process by which an organism forms carbohydrates by using chemicals rather than light.
A Food Chain
A sequence that links species by their feeding relationships.
They are organisms that only eat plants.
They are organisms that only eat animals.
They are organisms that eat both plants and animals.
They are organisms that eat dead organic matter.
They are detritivores that break down organic matter into simpler compounds.
They are consumers that primarily eat one specific organism or feeds on a very small number of organisms.
They are consumers that have a varying diet.
They are the levels or nourishment in a food chain.
This a model that shows the complex network of feeding relationships and the flow of energy within and sometimes beyond an ecosystem.
It is the circular pathway of water on earth from the atmosphere to the surface, below ground and back. It also known as the water cycle.
It is the movement of a particular chemical through the biological and geological parts of an ecosystem.
It is certain types of bacteria that convert gaseous nitrogen into ammonia.
It is the measure of the total dry mass of organisms in a given area.
It is a diagram that compares energy used by producers, primary consumers, and other trophic levels.
It is all of the biotic and abiotic factors in the area where an organism lives.
It is composed of all of the physical, chemical and biological factors that a species needs to survive, stay healthy and reproduce.
It states that when two species are competing for same resources, one species will be better suited to the niche, and the other species will be pushed into another niche or become extinct.
It is the species that occupy similar niches but live in different geographical regions.
Competition occurs when two organisms fight for the same limited resources.
It is the process by which one organism captures and feeds upon another organism.
A close ecological relationship between two or more organisms of different species.
It is an interspecies interaction in which both organisms benefit from one another.
It is a relationship between two organisms in which one receives an ecological benefit from the other, while the other neither benefits nor is harmed.
It is a relationship similar to predation in that one organism benefits while the other is harmed.
It is a measurement of the number of individuals living in a defined space.
It is the way in which individuals of a population are spread in an area or a volume.
It is a generalized diagram showing the number of surviving members over time from a measured set of births.
It is the movement of individuals into a population from another population.
It is the movement of individuals out of a population and into another population.
It occurs when a population size increases dramatically over a period of time.
A population that begins with a period of slow growth followed by a brief period of exponential growth before leveling off at a stable size.
It is the maximum number of individuals of a particular species that the environment can normally and consistently support.
It is a dramatic decline in the size of the population over a short period of time.
It is the factor that has the greatest effect in keeping down the size of the population.
Density-Dependent Limiting Factors
They are limiting factors that are affected by the number of individuals in a given area.
Density-Independent Limiting Factors
They are the aspects of the environment that limit a population growth regardless of the density of the population.
The sequence of biotic changes that regenerate the damaged community or create a community in a previously uninhabited area.
The establishment and development of an ecosystem in an area that was previously uninhabited.
It is the first organisms that live in a previously uninhabited area.
It is the reestablishment of a damaged ecosystem in an area where the soil was left intact.
