Ecosystem diversity

Biodiversity

human impact
exotic invasive species
Macro-evolution
evolution of an entire family of organisms in relation to all other organisms
Micro-evolution
evolution that occurs within a single population of organisms
What does micro-evolution cause
increases or decreases survival rate of organisms
increases biodiversity
Migration

food supply
water supply
climate change
reproduction patterns
What does migration cause
temporary or permanent appearance of new organisms in an ecosystem
can lead to loss of native species
