Representative sampling

Sampling that accurately represents a place/area by studying a manageable part if it.

Quadrat Sampling

A habitat is measured by dividing it into rectangles

Transect Sampling

A habitat is measured by dividing it into a line

Species evenness

The amount of individuals of each species present.

How to find diversity index?

D=(p1^-p1)(p2^-p2)(p3^-p3)…..

The higher the diversity index, is there greater species evenness (diversity) or less?

Greater

What is one thing organism need to survive?

Source of energy

What is another thing organism need to survive?

Source of carbon

Autotrophs

Make their own food

Heterotrophs

Feed on other organism instead of making their own food

OTU's

operational taxonomic units

photosynthesis

light energy (photons) is captured by pigments, such as chlorophyll, and is used to make ATP in the form of glucose.

cellular respiration

process of producing ATP by breaking down carbon-based molecules when oxygen is present.
