Question 5

Specialist species

Answer 5

narrow range of habitats/env. conditions / limited diet

Question 6

Loss of habitat leads to…

Loss of specialist species first
Loss of generalist species after
Species that need large territories (apex species; top of trophic chain) are also strongly impacted

Question 7

Richness:

Answer 7

of different species in an ecosystem
