Ecosystem Services
These ecosystem services provide products like food, oil, and lumber.
What are provisional services?
Biodiversity increases when this increases in an ecosystem.
What are resources?
The practice of using fewer resources so they last longer.
What is conservation?
This type of succession occurs where no soil exists.
What is primary succession?
The struggle between organisms for limited resources.
What is competition?
These services include activities like hiking and kayaking.
What are cultural services?
A species that strongly affects many other species in an ecosystem.
What is a keystone species?
This term describes the ability of an ecosystem to maintain biodiversity over time.
What is sustainability?
An example (from the notes) of an event that can cause secondary succession.
What is a forest fire?
A relationship where both organisms benefit.
What is mutualism?
This type of service includes processes like decomposition and nutrient cycling.
What are regulatory services?
This type of diversity helps species survive changes in the environment.
What is genetic diversity?
Humans harm ecosystems when they do this to habitats.
What is altering or destroying habitats?
This type of succession happens faster because soil already exists.
What is secondary succession?
The role an organism plays in its environment.
What is a niche?
These services are the most important because ecosystems cannot function without them.
What are supporting services?
These ecosystems are very biodiverse due to stable temperatures and long growing seasons.
What are rainforests?
This type of species is introduced by humans and disrupts ecosystems.
What are invasive species?
These communities form after long periods of succession and are stable.
What are mature communities?
This describes a relationship between you and the fleas in your hair.
What is parasitism?
These systems interact to create ecosystem services, like plants interacting with soil, water, and sunlight.
What are ecosystems and their components interacting?
This happens when all members of a species disappear from Earth.
What is extinction?
This process uses microorganisms to clean up pollution.
What is bioremediation?
These are the first organisms to grow in a new area.
What are pioneer species?
This process allows helpful traits to become more common in a population over time.
What is natural selection?
