Resource Availability
What are the three main resources needed for individual growth in ecosystems?
What are food, water, and shelter?
What is biodiversity?
What is the variety of life in ecosystems?
What term describes the process of recovery in an ecosystem after a disturbance?
What is succession?
The back of a sloth is hairy and covered with algae. The algae provide camouflage and extra nutrients for the sloth. The algae obtain water and shelter from the sloth’s long hair.
Mutualism
Abiotic
Non-living
How does population size change when resources become limited?
Population size decreases as resources become limited.
List the three levels of biodiversity.
What are genetic, species, and ecosystem biodiversity?
Name one way a nonnative species can affect a local ecosystem.
What is by removing a food source or changing the temperature?
A tapeworm absorbs all of the nutrients from a human
Living
What is competition in the context of resource availability?
Competition occurs when individuals or populations share limited resources.
Why is high biodiversity important for ecosystem stability?
It helps ecosystems recover from disturbances and maintain balance.
Are all changes in ecosystems negative? Give an example.
No, for example, forest fires can prevent overcrowding and add nutrients to the soil. (Other examples will be accepted as well)
An oxpecker eats ticks from the body of a rhino
Immigration
Coming into an area
Name an environmental factor that can affect resource availability in an ecosystem.
What is rain, droughts, or wildfires? (Other correct answers will be accepted as well)
What can cause a disturbance in an ecosystem?
What are wildfires, sudden population increases, or human activities?
What is one example of a gradual change in an ecosystem?
What are seasonal changes? (Other examples will be accepted)
Barnacles attach to a whale for transportation, the whale is unaffected
Commensalism
Emmigration
Leaving an area
How does competition for resources impact individual growth?
Limited resources can hinder individual growth, survival, and reproduction.
How does biodiversity influence an ecosystem's ability to recover from disturbances?
High biodiversity increases resilience and recovery capability after disturbances.
During the succession process, if you have to start from scratch with a new species, what is that species called?
Pioneer species
The shrimp digs and cleans the burrow. Outside of the burrow, the shrimp is almost blind and keeps its antennae on the goby fish. When the goby fish spots predators, it quickly moves into the burrow, and the shrimp follow
Mutualism
Symbiosis
A close relationship between two species that benefit at least one of the species
