Scientific Method
What do you need to make an observation?
Your five senses
Air, Soil, Water, Sunlight, and Temperature are examples of
abiotic factors
Five characteristics of life are
1. Cellular Organization
2. Growth and Development
3. Response to Stimulus
4. Metabolism
5. Homeostasis
6. Reproduction
7. Adaptation
8. Heredity
9. Water
This selected group favors higher populations
R-Selected
In this food chain grass -->grasshopper -->frog--> snake --> Hawk, the frog represents
a secondary consumer
This is the part of the experiment that is manipulated
Independent Variable
A group of organisms of the same species living in one area is a
population
Passing of traits to the next generation is an example of
Heredity
Few offsprings, parental care, high survival rate, Quality over Quality are all examples of
K-Selected species
In a forest habitat, foxes are known to eat rabbits however there has been a decrease in the fox population. What can you expect to happen
The rabbit population will increase
This is a testable explanation for an observation
Hypothesis
The largest ecological organization is the
Biosphere
True or False: It is now believed that spontaneous generation is how life began
False, this theory has been debunked. Biogenesis is today's theory
An S curve graph is indicating which selected group
K-Selected Group
True or False: Phylum, kingdom, class, family is in the correct order, if not correct it
False: Kingdom, Phylum, Class, Order
In order to test the rate of plant growth under different light conditions an experiment was designed using light boxes with filters. The dependent variable is ...
Rate of plant growth
This is the first level of an energy pyramid and ___% of energy is lost moving to the second level
autotrophs and 10
This is a tool used to identify an unknown item or organisms
Dichotomous Key
This selected group are known as generalist/opportunist
R-Selected Species
Elephant, Kangaroo, Zebra, Humans, Eagle, Whale, dolphin, Oak Tree, Tortoise...
A control group is important because...
It provides a comparison for the experimental group.
The concept that all organisms and the physical environment are connected and rely on eachother
Interdependence
True or false: There should always be at least 3 choices in each step based on the characteristics of the item.
False, there should be 2 choices
Carrying capacity and is represented by the variable K
Draw a K-selected Species Graph
S curve with the carrying capacity line
