Biology Unit 12: Ecology
Producers get energy from chemicals or the sun, and with the help of water, convert that energy into usable energy in the form of sugar, or food.
...
factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems
Abiotic
living things
Biotic
one organism benefits with no effects to the other
Commensalism
interacting group of various species in a common location
Community
is an interaction between organisms or species in which the fitness of one is lowered by the presence of another interspecific competition- competition between two or more different species
Competition
is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system
Ecosystem
both organisms benefits
Mutualism
one organism benefits with the extent of harm on another
Parasitism
a group of individuals belonging to the same species that live in the same region at the same time
Populations
organisms that make their own food from sunlight and/or chemical energy from deep sea vents
Primary producers
a close, long-term interaction between two different species
Symbiosis
What are primary producers known as?
autotrophs
chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents
autotrophs
the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment
carrying capacity
organisms of an ecological food chain which receive energy by consuming other organisms
consumers
What are consumers formally referred to as?
heterotrophs
Heterotrophs include:...?
include animals, bacteria and fungi.
competition that only involves one species
intraspecific competition
environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem
limiting factor
What is the most common example of a producer?
plants
What is the base of every food chain?
primary producers
organisms that make their own food; they are also known as autotrophs
