|
What is ecology?
|
The scientific study of the interaction of organisms with the environment
|
|
|
What is the difference between ecological time and evolutionary time?
|
Events that occur are ecological time while evolutionary time is the adaption to those events
|
|
|
The environment includes…
|
Living = biotic and nonliving = abiotic components
|
|
|
Name at least two subfields of ecology and their definitions.
|
Organismal Ecology: studies how an organisms strucutre, physiology, and (animals) behavior interacts with environment
Population Ecology: studies factors that determine the #of individuals in an area Community Ecology: studies the interactions of all organisms and other factors together Ecosystem Ecology: studies energy flow and chemical recycling in an area Biogeography: studies factors that make organisms appear in one area, but not another |
|
|
Name at least 3 factors that contribute to biogeography
|
Dispersal: organisms movement to and from the general local; if isolated, restricts geographic range of organism; transplantation
Behavior and habitat selection: some behaviors prohibit an organism from expanding Biotic factors: predator/prey relationships, interactions with other species, competition Abiotic factors: temperature, soil, water, sunlight, wind, etc |
|
|
What four abiotic factors make up the climate?
|
Temperature, water, sunlight, wind
|
|
|
What are the two types of climates?
|
Macroclimate
microclimate |
|
|
What is the primary factor that contributes to the Earth’s climate patterns?
|
The amount of energy input by the Sun and the planet’s movement in space
|
|
|
What is the significance of the equinoxes and solstices?
|
During the equinoxes, all areas of the planet receive 12 hours of sunlight and 12 hours darkness. During the solstices, winter/summer begin.
|
|
|
What phenomenon generates global ocean currents? Why would anthropogenic climate change affect this?
|
Wind patterns. Because the increased heat in the atmosphere would change the wind patterns, which would change everything
|
|
|
What controls the temperature of land masses?
|
Bodies of water
|
|
|
What affect do mountains have on a local climate?
|
Moderate rainfall, amount of sunlight, and the temperature
|
|
|
What is a biome?
|
The major types of ecological associations that occupy broad geographic regions of land or water
|
|
|
What is the largest type of biome on Earth?
|
Aquatic biomes. Oceans are 75% of the Earth’s surface. They MAJORLY impact the climate
|
|
|
What zone in the root is responsible for making the root grow further into the ground?
|
Zone of elongation
|
|
|
Which of the following cells are dead at functional maturity?
Sieve-tube members Vessel elements Tracheids Companion cells A and B B and C All are dead None are dead. |
B and C
|
|
|
Which is more negative, the water pressure in the root or outside the root?
|
In the root
|
|
|
From where does the water come that makes the phloem sap flow?
|
The xylem
|
|
|
What part of the plant is alive? The outer part or the innermost part?
|
The outermost part.
|
|
|
How many microspores does each pollen grain contain?
|
