Unit 5 - Biology

Biotic

Any living or ones living component of an ecosystem, including animals, plants, fungi, and microorganisms

Abiotic

Of or characterized by the absence of life or living organisms

ecosystem

A system or group of interconnected elements formed by the interaction of a community of organisms with their environment

Independence

The quality or condition of being independent or mutually reliant on each other

Carrying capacity

The maximum equilibrium number of organisms, a particular species can be supported indefinitely in a given environment

Exponential growth

The growth of a system in which the amount being added to the system is proportional to the amount already present the bigger the system is the greater the increase

Logistic growth

A population growth pattern, where the rate of increased flows down in the levels off as the population size approach is a maximum sustainable limit known as the carrying capacity

Limiting factor

Environmental resources or conditions, such as food, water, space or temperature that restricts the growth, abundance or distribution of an organism or population within an ecosystem

Density independent factor

Environmental abiotic forces that affect a population sides, regardless of its density or size

Predation

A biological interaction where a predator organism feeds on another the prey driving the energy flow population cycles in evolutionary adaptions within an ecosystem

Mutualism

Relationship between different species were both partners benefit enhancing survival growth or reproduction

Commensalism

The type of symbiotic relationship were one organism, the commensal, benefits, obtaining food, shelter, or transportation, while the other the house is neither harmed

Parasitism

Symbiotic relationship with one organism, the parasite lives or on inside a house, organism obtaining nutrients at the host expense and causing it hard

Density dependent factor

Environmental variables that affect the population growth rates based on population density

symbiosis

A long-term interaction between different species ranging from beneficial to harmful

Competition

Arrival between individual groups and entitled striving for the same often limited goal or resource
