Relationships in an Ecosystem
What is commensalism?
When one organism benefits while the other is neither helped nor harmed.
What is one major way the moon affects the Earth?
TIDES
What does a transverse wave look like?
See student's drawing.
Give an example of a natural hazard
All energy originally comes from what?
The Sun
What is predation?
When an animal eats another animal to obtain nutrients
How does the Sun’s gravitational pull affect everything in our solar system?
Keeps everything in perfect orbit
What does a longitudinal wave look like?
See student's drawing.
Give an example of a natural disaster
Hurricane Katrina
List two weather tools meteorologists use to predict the weather.
Barometer
Thermometer
What is mutualism?
When both species benefit.
What is the order of the Moon, Sun, and Earth during a solar eclipse?
Sun, Moon, Earth
If a wave has a frequency of 50 Hz and a speed of 700 m/s, what is the waves wavelength?
14 wavelength
What is the difference between a natural hazard and a natural disaster?
A natural hazard hasn't happened.
A natural disaster has.
List the four weather fronts.
Warm Front
Cold Front
Stationary Front
Occluded Front
What is parasitism?
When one organism benefits and the other organism is harmed.
What is the order of the Moon, Sun, and Earth during a lunar eclipse?
Sun, Earth, Moon
If a wave has a wavelength of 58 and a frequency of 7 Hz, what is the waves speed?
406v
What is the difference between a food chain and a food web?
A food chain is a hierarchical order of animals consuming one another. The higher up you go the higher on the food chain you are.
A food web includes multiple organisms from the ecosystem. It shows multiple organisms that one animal can eat and multiple organisms that eat it.
Why do some animals live in packs?
Protection
Help take down larger prey
Help raise young
Give an example of a mutualistic, parasitic, and commensalistic relationship between organisms.
Mutualism- hippo and woodpecker
Parasitic- tic and a human
Commensalistic- whale and a barnacle
List the eight phases of the moon.
new moon, waxing crescent,first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent
Draw and label a transverse wave. (crest, trough, amplitude, and wavelength)
See student's drawing
How does resource availability impact the lives of individual organisms and the entire ecosystem?
Student response
Why do some animals survive in certain environments better than others?
They are better equipped. The habitat has all of the necessities for them to survive and the climate is similar to their native home.
