a particular section, group, or type of people or animals living in an area or country.
population
an ecosystem's ability to withstand and recover from disturbances
ecosystem resilience

independent variable
environmental conditions or resources that restrict the growth, abundance, or distribution of an organism or population in an ecosystem
limiting factors
dependent variable
the factor being measured or observed, and its value is believed to be influenced by the independent variable
biomass pyramid
a graphical representation of the total amount of living or organic matter (biomass) present at each trophic level in an ecosystem
an organism that cannot produce its own food and must obtain energy by consuming other organisms
consumer
carrying capacity
the maximum number of individuals of a species that an environment can support indefinitely
serves as a benchmark or baseline against which the experimental group is compared
control group
control variables or constant variables
variables held constant
confounding variables
extraneous factors that can distort the relationship between the independent and dependent variables in a study
producer
a graphical representation of the total amount of living or organic matter (biomass) present at each trophic level in an ecosystem

glucagon
hormone stored in the pancreas that helps regulate blood sugar levels
interaction between organisms, populations, or species, in which birth, growth and death depend on gaining a share of a limited environmental resource.
competition
a protein molecule that speeds up chemical reactions without being consumed in the process
enzyme
the capacity to withstand or to recover quickly from difficulties
resilience
