WHICH ONES ARE BIOTIC AND WHICH ARE ABIOTIC?
BIODIVERSITY
The number of different species of plants and animals in an area.
BIODIVERSITY
THE GREATER THE VARIETY OF SPECIES, THE HEALTHIER THE BIOSPHERE IS!!
WHY BIODIVERSITY LEADS TO A MORE SUSTAINABLE ECOSYSTEM
Sustainability is the ability to maintain something over a long period of time.
More Species =More Links in the Food Chain
More Plants = More Food for other animals (oxygen too)
More Genes = Better Chance for Survival thru Adaptation
Variety of Ecosystems = More Habitat for different Species
ENVIRONMENTAL CHANGES1. How do changes in environmental
conditions affect the survival of individual organisms and
entire species?2. How do populations respond to long-term
environmental changes?3. How do populations respond to short-
term environmental changes?4. How does human activity affect natural
systems?
