Population

group of individuals of same species

Community

All populations of different species living in a specific area.

Landscape

broader patch work of ecosystems-linked through flow of matter, energy, and organisms

biome

Broad scale regions dominated by similar types of ecosystems

biosphere

the earth, or layer of earth that supports life

Hypothesis

A proposed explanation or educated guess that can be tested through experimentation and observation.

theory

A well-substantiated explanation of an aspect of the natural world, based on a body of evidence and tested hypotheses.

model

A representation or simulation of a system or phenomenon used to understand, predict, or explain its behavior in biology and other sciences.

binary data

Data that can take on two possible values, often represented as 0 and 1, used in various biological analyses.

frequency distributation

A display of how often each value occurs in a dataset.

Abiotic Factors

what factors affect the ecosystem the most

Weather

state of the atmosphere in a certian place or time

Climate
