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?
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
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?
