Biodiversity
n Biodivers i ty can be measured on many biological levels ranging fromgenetic diversity within a species to the variety of ecosystems on Earth, but the term most commonly refers to the numberof different species in a defined area.
n Biological diversity - presence of many different types of living organisms.

Ecology
n Distribution and abundance of living
organisms and their interactions with
the environment
q Abiotic – nonliving

Native grasses
•Grow in native prairie habitat,
where they:
1.Provide structural support for wildflowers
2.Fill in gaps that wildflowers can’t early in
establishment, decreasing weed pressure
3.Have root systems of different depths that
complement wildflowers

Natural enemies
Predators: both young andadults feed directly on other insects.
Parasitoids: develop on or in one host insect, emerge as adult, eventually killing host.
