Ecosystem/ Succession
What happens to an ecosystem when it loses its biodiversity?
The ecosystem will begin to deteriorate
How many levels of consumers do we have? What are the names?
3: primary, secondary, and tertiary
What is the first level of organization?
Organism
When plants grow towards light
The rainforest
How does secondary succession restore a region that has been destroyed?
Increases the number of species over time
Sagebrush, rats, snakes, coyotes
What is the second level of organization?
Population
A non-living part of the ecosystem
Abiotic factor
How will an increase in the number of frogs impact the food chain?
The pythons and eagles will have more to eat
How does increased biodiversity affect the sustainability of an ecosystem?
A greater variety of species allows more organisms to adapt after changes occur
If a producer goes extinct, what will happen to the secondary and tertiary consumers?
They will also go extinct
What is the third level of organization?
Community
A forest grows back after a natural disaster
Succession

Producer to consumer OR consumer to producer
Producer to consumer
What is the fourth level of organization?
Ecosystem
The ability of an ecosystem to supply food, drink, and other necessities of life.
Sustainability
How is energy transferred during photosynthesis?
Radiant energy is converted into chemical energy
Mosses and lichens
Common pioneer species
What is the fifth level of organization?
Biome
A plants response to gravity (plant growth changes direction)
Geotropism
Why would a bird evolve to have a different beak from its ancestors?
To reduce competition so it can eat different types of food
