ecology checkpoint Flashcards
the study of interactions of living organisms with one another and with their environment
ecology
breaks down dead organic matter
decomposers
a group of living and nonliving things in a place that has a specific climate, landforms, vegetation, and other living species
ecosystem
Living and once living parts of an ecosystem
biotic factors
nonliving parts of an ecosystem
abiotic factors
when plants use sunlight to make sugar molecules aka food
photosynthesis
organisms that make their own food
producer
organisms that get their energy by eating other organism
consumers
only eats plants
herbivore
only eats animals
carnivore
eat both plants and animals
omnivore
eats decaying biomass
scavengers
when and organism eats another organism
energy transfer
a sequence in which energy is transferred from one organism to the next as each organism eats another organism
food chain
the energy that is passed from one level to the next
trophic energy
Primary producers only pass 10% of their energy to primary consumers, who only pass 10% of their energy to secondary consumers…. Etc.
10% rule
the part of the earth that contains all ecosystems
biosphere
population that live together in a defined area
community
group of organisms of one type that live in the same area
population
individual living thing
organism
a large region characterized by a specific type of climate and certain types of plant animal and communities
biomass
-Disease
-Predators
-Competition
-Amount of food & water available
-Natural disasters
limiting factor
graph with no limiting factors, it keeps growing and going up
j-curve graph
graph that shows the effects of limiting factors on a population (carrying capacity)
s-curve graph
