a living thing
organism
an environmental factor that restricts growth or distribution of a population in an eco system
ex. food, water, shelter, space
limiting factor
a group of different species of organisms that live in the same geographical area at the same time and interact with each other
community
organisms that create their own food from an energy source (such as plants photosynthesizing)
double points for knowing both words
producers/ autotroph
double points if you know both!
relationships between two or more different species of organisms, where they interact with each other
symbiosis
detrivore/ decomposer
a species average population size in a particular habitat
(how many deer can a forest sustain)
carrying capacity
a community of living organisms (biotic factors) interacting with their physical environment (abiotic factors) within a specific geographic area, where energy flows and nutrients cycle between all components, creating a complex network of relationships
ecosystem
something that must eat or absorb another organism to obtain energy
double points if you know both words
consumer/ heterotroph
a type of symbiosis that benefits both organisms
(happy/happy)
double points if you can give an example
mutualism
a group of the same species
population
interactions between organisms in which both require a resource that is in limited supply
competition
a large geographical region characterized by a specific climate, vegetation, and animal life.
100 extra points each for up to 5 of the main examples
biome
aquatic, grassland, forest, desert, tundra
herbivores on the energy pyramid
primary consumer
a type of symbiosis that only benefits one organism but does not harm the other organism
(happy/meh)
extra 200 pts for an example
commensalism
a state of equilibrium in an biological system
homeostasis
non living factors
up to 300 extra points for up to 3 examples
(100 each)
abiotic factors
all living things on earth
biosphere
carnivores that eat herbivores on the energy pyramid
secondary consumers
type of symbiosis that only benefits one organism and harms the other organism
(happy/sad)
extra 200 points for an example
parasitism
area and resources used bu a particular species
habitat
living factors
biotic factors
average weather for a large area
climate
carnivores that eat other carnivores
tertiary consumers
an organism at the top of the food web that keeps the entire ecosystem in balance (the ecosystem will collapse if they are removed)
200 extra points for an example
keystone predator
