What are the levels of ecosystem (smallest to largest)
1.) Individual (Smallest) 2.) Population 3.) Community 4.) Ecosystem 5.) Biomes 6.) Sphere (Largest)
Individual
Members of one species
Population
A group of animals that can reproduce
Community
Interdependent organisms of different species in a habitat
Ecosystem
Various communities of living and non-living orgainisms
Biome
A geographical/biological region
Spheres
Biosphere - Life Lithosphere - Land Hydrosphere - Water Atmosphere - Air
What is the difference between a biome and a ecosystem
Biome - Referred to by its physical factors Ecosystem - The place where biotic and abiotic factors interact
What is the difference between ecosystem and habitat
Ecosystem - How biotic and abiotic factors interact Habitat - Where the species population lives.
What are the two main types of ecosystems
1.) Terrestrial Biomes 2.) Aquatic Biomes
What are the subtypes of the water-based biomes
Freshwater and Marine
What does the Endangered Species Act do
Protect endangered species and help create a better understanding of how humans affect the environment
Negatives of the Endangered Species Act
It slows development and protection comes too late.
Mid-Ocean Ridge

Convergent Boundary
Active Margin
Convergent or Divergent Boundaries
Forces on two adjacent continental plates are causing tension stress. What will be the likely outcome?
The plate will separate creating continental drift
Active Margin
A
Hotspot
D
Sea-floor Spreading
B
Passive Margin
C
Similar in size and latitude, Japan and California both have another unfortunate similarity. They are both subject to earthquakes. There are however, still differences here. First, Japan is much more seismically active than California. Second, the reason for these earthquakes is different. Japan’s earthquakes stem from convergence within their four tectonic plates while California’s earthquake come from the transform nature of their faults.
A. The boundaries of Japan contribute to the Pacific Ocean shrinking B. Parts of California may break away from the continent through continental rifting on the fault lines E. The compression stress between Japan and the Pacific Ocean may contribute to the seismic instability
