It's Alive!
This is the word for the living factors of an ecosystem
What is biotic?
This kind of organism eats producers.
What is an herbivore/primary consumer?
This is the name of the relationship between two species that benefits both
What is mutualism?
This is a species that evolved in the environment where it lives.
What is a native species? (or indigenous)
Clownfish with various patterns of stripes is this type of diversity
What is Genetic Diversity
This is a group of organisms of the same species, in the same place, at the same time.
What is a population?
This is the amount of energy taken in at one trophic level that is available to the next trophic level.
What is 10%?
If one organism lives off of a host and harms the host.
What is parasitism?
These are two examples of pioneer species that can grow on bare rock and build soil.
What are mosses and lichens.
Species _______ is how many different kinds of species there are
What is Richness
This is all of the populations in an ecosystem.
What is a community?
This is how we get our Nitrogen
What is by eating food?
When one organism benefits and the other is not helped or harmed.
What is commensalism?
Some benefits of this include increased sunlight on the forest floor, germination of seeds, and enriching the soil.
What is wildfire?
Name two reasons why biodiversity is important:
Help ecosystems stay balanced
Help ecosystems recover from natural disasters
This is an example of a density-independent limiting factor of population size.
What is a natural disaster? such as a flood, forest fire, volcanic eruption, etc.
Denitrification is when
Solid nitrogen (nitrates and nitrites) are converted into nitrogen gas by microorganisms
This is the pattern you should see in a predator-prey graph.
What is the prey population should increase before the predator population increases and prey population should decrease before the predator population decreases.
These are three characteristics of most invasive species.
What are successful/rapid reproduction, no natural predators, adaptable to many habitats/conditions, out competes native species
Scientists estimate population size and species diversity by sampling organisms in an ecosystem. Name three of these sampling methods.
Transect, quadrat, mark and recapture, removal sampling
The definition of carrying capacity
What is carrying capacity is the number of a single species that an ecosystem can sustain?
The reason an energy pyramid is shaped like a pyramid.
What is there need to be more producers to support fewer consumers due to energy being used up by life processes?
In a food web of grasses, deer, and wolves, how might an increase in the wolf population affect the grasses?
What is the population of grasses would increase because there would be fewer deer
A flood destroys an ecosystem and a new ecosystem grows in its place. This is the name of that process.
What is secondary succession?
I sampled fish from a pond, 5/7 were marked. Originally 15 were marked, what is the estimated population size of the fish?
What is 21?
