These are two things that cause a population to grow.
What are births and immigration?
100
These types of organisms are at the bottom of the food web; they get their energy through photosynthesis.
What are producers/autotrophs?
100
These are the non-living factors (light, rain, temperature, etc.) that affect an ecosystem.
What are abiotic factors?
100
This is the definition of biodiversity.
What is the number of different species that live in an area?
100
What is a QUANTITATIVE observation?
What is a number?
200
These are two things that cause a population to shrink.
What are deaths and emigration?
200
These organisms must eat other organisms to get energy; they cannot produce their own energy.
What are consumers?
200
This is all of the populations of different species that live together in an ecosystem.
What is a community?
200
Increased biodiversity makes an ecosystem more _________
What is stable?
200
You should choose this type of graph to show how something is changing over time.
What is a line graph?
300
This is the maximum number of individuals in a population that can be supported by the resources available in an ecosystem.
What is the carrying capacity?
300
This is where the energy in most ecosystems comes from.
What is the sun?
300
This process is the evolution of an ecosystem; it starts simple and becomes more complex over time. (Ex. starts with lichens, then grasses, then shrubs...)
What is succession?
300
When a natural disaster wipes out most of the organisms in an area, some are able to survive because each type of organisms occupies a different __________.
What is a niche?
300
This is what TAILS stands for.
What is title, axis, interval, label, scale?
400
These are the factors that limit the carrying capacity of a population.
What are resources (food, water, shelter, space, etc.)?
400
This is the amount of energy that's transferred up each trophic level (ex. producer to primary consumer).
What is 10%?
400
This type of succession occurs in a brand new ecosystem.
What is primary succession.
400
Increased biodiversity leads to greater stability in an ecosystem because of these reasons (name one).
What are more resistance to disease, more food sources, more links in the food web?
400
In an experiment that measures the size of a population, every month, this is the independent variable.
What is month?
500
This is what tends to happen to the size of a population when an environment is stable.
What is it stays steady (around carrying capacity)?
500
The carbon that enters the food web by photosynthesis comes from this molecule in the atmosphere.
What is carbon dioxide?
500
This could cause secondary succession to occur.
What is a fire, a flood, anything that wipes out the original ecosystem.
500
Non-native species that are introduced to an environment by humans can cause severe disruption of an ecosystem because of the lack of these in the ecosystem.
What are predators?
500
This is the point in an experiment where you would make conclusions.
