ecology Flashcards
level of energy within the energy pyramid
trophic level
all of the mass of living things in the world/area
biomass
the rule that states only 10% of energy in an energy pyramid moves to the next level
10% rule
the process plants go through to create natural sugars
photosynthesis
the process non plant cells go through to convert nutrients to energy
cellular respiration
model that states the energy available for consumers decreases as is travels through a typical food chain or food web
energy pyramid
the organism in the top spot of the energy pyramid
tertiary consumer
the organism in the second to top spot in an energy pyramid
secondary consumer
the organism at the level above the producer
primary consumer
the organism or sun at the bottom level of an energy pyramid with the most energy
producer
all members of the same species in an area
population
an individual within a species
organism
living parts of an ecosystem
biotic
non living parts of an organism
abiotic
study of organisms and their interactions with their environment and other organisms
ecology
several populations living and interacting in one area
community
community plus abiotic factors
ecosystem
many similar ecosystems within a large area
biome
all the biomes of the entire world
biosphere
change in number of individuals over time
growth rate
under ideal conditions in which organisms benefit always
exponential growth
resources are shared and not endless results in s shaped curve
limited growth
number of organisms an environment can hold
carrying capacity
