Intro to Life Science
Name the IV: Mr. Ryan tests different types of water to see which helps his tomato plant grow the most.
Types of water
All the living things in an area are called?
Biotic Factors
Explain what makes something a producer in a food web.
It makes its own food/energy (plants)
Define parasitism
One organism benefits, the other is harmed
Which organism is the predator and which is the prey in this food chain: Mouse --> Bird
Predator: Bird. Prey: Mouse.
Name the DV: Mr. Ryan tests different types of water to see which helps his tomato plant grow the most.
Plant growth
Bees swarming to prevent an intruder from entering their hive is an example of what characteristic of living things?
Response to stimuli
Organize these in order of smallest to largest: Ecosystem, community, biosphere, population
Population, community, ecosystem, biosphere
Give an example of organisms that could make up a community.
(Answer must contain different living species and NO abiotic factors)
Name any one potential limiting factor for plants in a meadow
What is special about a controlled experiment?
It has only ONE IV
All the non-living things in an area are called?
Abiotic factors
Primary - eats producers (eats first). Secondary - eats consumers (eats second).
Define commensalism
One organism benefits, the other is neither helped nor harmed
What is the name for any individual living thing?
Organism
What is the name of the tool that measures liquid and is read by looking at the bottom of the meniscus curve?
Graduated cylinder
What do ALL cells need to carry out life processes?
Energy
The maximum amount of organisms an ecosystem can support is called?
Carrying capacity
Define mutualism
Explain the difference between primary and secondary succession.
Primary: No living things left, just rock. Secondary: Some living things left.
What is the difference between an observation and an inference?
Observations are provable facts; inferences are guesses based on observations.
A caterpillar becoming a butterfly is an example of what characteristic of living things?
Growth & Development
What could be some limiting factors for the amount of rabbits that can live in an area?
The amount of resources available (food, living space, shelter) and the amount of predators.
What is the difference between predation and competition?
Predation is the relationship between predator and prey. Competition is organisms competing over the same resources.
In an energy pyramid, which organisms are least supported? The ones at the top, in the middle, or at the bottom?
Top (they have less resources available to them)
