Vocabulary CH. 1
Ecosystem
all the living thing and non living things in a given area.
Tropic Levels
Level 1- Producers
Level 2- Primary Consumers
Level 3- Secondary Consumers
Level 4- Tertiary Consumers
Population
All organisms of the same species that live in the same area at the same time.
Aquatic Succession
Sediment carried by rainwater and streams can accumulate on the bottoms of ponds, lakes and wetlands. Eventually the water will disappear and the area will turn into land.
Biodiversity
The number and variety of organisms found in a specific region.
Food Web
A model that shows the amount of energy in each link of a food chain.
Name 4 Natural Disasters
Tornado, Drought, Wildfire, Volcano
Climax Community
A stable community that no longer goes through major ecological changes.
Effects of Aquatic Succession
Damage habitats. clog waterways, and cause flooding. Which can cause loss of habitats. change in available nutrients, and decrease light availability for plants.
Biodiversity Index
The measure of species diversity in a given location.
Energy Pyramid
A model that shows the amount of energy available in each link of a food chain.
What is Eutrophication?
A body of water becoming nutrient and rich.
Ecological Succession
The process of one ecological community gradually changing into another.
List 6 different types of Measurements
Transect Sampling, Netting, Surveys, Aerial Photo, Quadrant Sampling, Canopy Fogging.
Resilience
The ability of an ecosystem to maintain balance even in the face of significant disturbance.
Natural Disaster
An event caused by nature that results in widespread damage.
Describe Nutrient loading. Give an Example
Adding nutrients into ecosystems from human activity.
EX: Planting Trees
Pioneer Species
The first species that colonizes new or untouched land.
Importance of Biodiversity
-Ecosystem health, stability and sustainability.
-Ecosystem Changes
-Resilience
-Sustainable Ecosystems
Sustainable Ecosystem
An ecosystem that can remain diverse and productive over time without outside influence or assistance.
Dynamic Equilibrium
Compare/Contrast Primary & Secondary Succession
Primary Succession occurs on bare, lifeless ecosystems without soil. While Secondary Succession happens in ecosystems with existing soil that experienced a disturbance.
Primary/Secondary Succession
Primary- Establishment of a community in an area of bare rock, or bare sand. No topsoil.
Secondary- Orderly change that occurs in a place where soil remains after a community of organisms have been moved.
Ecosystem Services
-Supporting Services
-Regulating Services
-Cultural Services
-Provisioning Services
Genetic/Species Diversity
Genetic- The amount of genes or inherited traits that are present in a population.
Species- The number and quantity of each species in an ecological community.
