Factors of Organism Flashcards
What is biotic and abiotic components of an ecosystem?
Biotic = alive Abiotic = dead
Define population
A group of organisms of the same species that live in the same habitat or ecosystem at the same time
Define community
All the organisms of various species that share a habitat or ecosystem
Define biodiversity
The number of species in an ecosystem
Define indicator species
A species sensitive to small changes in environmental conditions
Define habitat
A place or type of environment with conditions suitable for the survival of an organism or population of organisms
Define ecotone
A transition area between ecosystems
Define biome
A large geographical region with a specific range of temperatures and precipitation, and the organisms that are adapted to those conditions of temperature and precipitation
What does carrying capacity of an ecosystem mean?
The maximum number of individuals that can be supported by an ecosystem
Define bioaccumulation
Substances (pesticides, chemicals, etc.) that the organisms absorb at a rate faster than which substance is lost
What are adaptions for survival?
What helps organisms meet their basic needs
ex) Koala have claws to climb trees
What is an ecological niche?
An organism’s role in an ecosystem, consisting, of its place in the food web, its habitat, its breeding area, and the time of day at which it is most active
What is an animals biotic potential and factors?
Biotic potential is the maximum number of offspring that a species could produce with unlimited resources. Biotic factors is a living factor that influences an organism.
What is limiting factors?
Things that prevents the population from growing like food shelter water. Factors in the environment that can prevent populations from attaining their biotic potential. Any resource that is in short supply is limiting factor on a population.
What is environmental resistance?
Any factor that limits a population’s ability to realize its biotic potential when it nears or exceeds the environment’s carrying capacity
