What is a hypothesis?
An educated guess
What is a line graphs used for?
Showing change over time
What are three biotic factors and three abiotic factors that would be present in a pond ecosystem?
Examples may include:
Biotic- grass, fish, turtles, algae, frogs, etc.
Abiotic- water, air, sunlight, temperature, salinity, etc.
Who created the classification system we use today?
Linneaus
An organisms specific role or position within the ecosystem.
Niche
Why is it important to follow lab safety rules?
They keep you safe!
What is a circle graph used for?
Comparing parts of a whole
Why would a decrease in the mice population in an ecosystem also affect the eagle population?
What are the levels of classification in order from most broad to most specific?
Domain, kingdom, phylum, class, order, family, genus, species
The two-part naming system used to classify living organisms
What do you use to make an observation?
Five senses
What tool is used for measuring volume?
Graduated Cylinder
What is the difference between physical (structural), functional (physiological), and behavioral adaptations?
Physical: Outward appearance, body part
Functional: Internal function
Behavioral: Action
What two levels of classification are used in the scientific name of organisms?
Genus and Species
The curve in the surface of the water when it is in a graduated cylinder
Meniscus
What is the first step of the scientific method?
Make an observation
What are the three base units we discussed?
Grams, Liters, and Meters
Name and describe the three types of symbiotic relationships.
Mutualism (both organisms benefit)
Parasitism (one organism benefits, one is harmed)
Commensalism (one organism benefits, one is unaffected)
What are the three domains?
Eukarya, Eubacteria, and Archeabacteria
What is the classification tool that allows you to pick between two characteristics in order to name an organism?
Dichotomus Key
What is the first thing you do when something goes wrong during an experiment?
Tell your teacher
What is the correct order of metric prefixes?
Kilo, Hecto, deca, base units, deci, Centi, milli
Describe the flow of energy through the different trophic levels of an energy pyramid. What is the order of each level, where is the most energy found, and by how much energy gets passed along to each level?
Producers--Primary Consumers--Secondary Consumers--Tertiary Consumers--Quadrinary (Apex) Consumers. The majority of the energy is at the bottom of the pyramid with the producers. The least amount of energy is at the top with the apex consumers. Each level only gets 10% of the energy from the previous level.
What are the six kingdoms?
Eubacteria, Archeabacteria, Protista, Animalia, Plantae, Fungi.
The ability of living things to maintain a stable internal condition
Homeostasis
