Ecosystems
What are the levels of organization in an ecosystem?
Organism, population, community, ecosystem, biome, biosphere
Define Biome
A large area with similar conditions that determine the plants and animals that live there
Identify 3 aquatic biomes that can be a source of human drinking water.
lakes ponds river streams
What is a carbon source
a carbon reservoir that releases more carbon than it absorbs
Identify the source of energy that drives the hydrological cycle
oh mr. sun, sun. Mr. Golden Sun
What is a food web?
a system of interlocking food chains
Detine symbiosis
a relationship between two organisms either short term or long term
Identify two characteristics of a biome
Temperature and precipitation
define marine biome
a large area with similar conditions in the ocean
Define carbon sink
reservoir of carbon that stores more carbon that it releases
Identify two hydrological sinks and two hydrological sources
sinks, ocean, infiltration,
sources, runoff, precipitation
Discuss the difference between a food web and a food chain
food chain is one linear way of energy flow, food web is multiple chains interlocked together with energy flowing in multiple direciton
Define mutualism and provide and example
a relationship between two organisms where they both benefit from each other
Describe why there is a predictable pattern in terms of where biomes are located on earth.
A pattern of temperature generally follows the latitude on Earth with temperature going down as you move away from the equator
Describe an estuary biome. Identify and example on Maui
The area where the river emptyʻs into the ocean Wailuku, Waiehu, Waikapu, Waihee, Maliko, Makamakaʻole, Kahakuloa, Honokohau river mouths
identify a short term and long term carbon reservoir
ocean fossil fuels
Identify TWO critical hydrologic reservoirs for human drinking water.
Aquifers, ice caps
Identify what arrows in a food chain represent
flow of energy
Define commensalism and provide an example
a relationship between two organisms where one benefits and one is unaffected
Explain how the location of a biome could change over time
Climate change will increase temperatures which change the type of biome that it is
Describe freshwater wetlands. and provide two Maui examples
an area with submerged soil for most parts of the year but shallow enough for emergent plants. Kealia, Kanahā
Explain how photosynthesis and cellular respiration cycle carbon.
between the atmosphere and biosphere in a steady state.
They cycle carbon among themselves without an excess or decrease in overall carbon which makes that process carbon neutral
describe infiltration
the process of precipitation seeping through the earth into the aquifers
what is a tropic cascade
an ecological phenomenon that happens when a top predator is killed and multiple reactions are felt across the ecosystem
Describe competition for a limited resource
Competition for a limited resource is a negative thing for both populations because it increase the amount of organisms that fight for the same food and shelter
Identify one characteristic of a biome and explain how that characteristic determines the community of organisms found in the biome
Precip or temp
Describe the intertidal zone and provide two Maui examples
area between the high tide and low tide. Opihi and aama crab
Explain why combustion of fossil fuels increases the carbon stored in the atmosphere.
carbon that is historically stored underground is burned and is now stored in the atmosphere
Identify one process in the hydrological cycle
evaporation, condensation, precipitation, runoff, infiltration
Make a claim about how the removal of a population of bats from an ecosystem could impact at least two other populations in that ecosystem
Bats diet will increase in population, animals that eat bats will decrease
Define resource partitioning and explain how it reduces competition
the diving of resources so populations do not have to compete against each other for food or housing
Describe how organisms are adapted to live in the intertidal zone.
thich skin or shells to prevent drying during low tide and the ability to stick onto to rocks to prevent flying away when waves crash
Explain how the rate of carbon in the atmosphere has changed the carbon cycle within the last 250 years
fossil fuels burning puts carbon reservoirs in the air instead of underground and caused things like climate change
Identify the other 4 processes in the cycle
evaporation, condensation, precipitation, runoff, infiltration
Draw a food chain and identify the secondary and tertiary consumers
producer, primary consumer, secondary consumer, tertiary consumer
