Why are insects so diverse? (6)

Answer 7

Size

high fecundity

sensory and neuromotor system (evades capture)

short lifespan (allows genetic change commonly)

Coevolution (evolves with predator)

metamorphosis (larvae and adult dont compete for food)

Answer 8

the science of classifying organisms

Question 9

What is traditional taxonomy?

Answer 9

categorizes insects based on morphology and behavior

described species are given two names
Genus
Species

Question 12

above

Question 13

Prefix sub- meaning

Contain the genus and species
Italicized
Names of authors of species follow after

How are ID books classified?

Answer 18

Using taxonomy

Uses family level
