what do chemical processes include
series of steps in which organisms transfer energy
includes the formation of clouds, precipitation and the flow of running water
includes the formation of heat
includes processes in which an organism breaks down energy
what is ecology?
the study of how humans interact between each other
the study of interactions between organisms and their environment
each step in a food chain or food web
elements that pass from one organism to another among parts of the biosphere through closed loops
what consists in a biosphere
all living things on Earth
all living things on earth except abiotic factors
a population
an individual, population, and community
the biome
what are primary producers
the secondary producers
carnivores
the first producers of energy-rich compounds that are later used by other organisms
carnivores, herbivore, omnivore, scavengers, decomposers
plants and animals
what are food chains
each step in a food chain
a series of steps in which organisms transfer energy by eating and being eaten
processes that deal with food chains
a series of food webs in which organisms can transfer energy easily
what is a trophic level
elements that pass from one organism to another
the level in which primary producers are
another word for pyramids of mass
each step in a food chain or food web
what are biochemical cycles
processes that deal with land
cycles that include the transition of organisms through the biosphere
elements that pass from one organism to another among parts of the biosphere through closed loops
the repetition of biochemical processes
what are geological processes
includes processes that deal with land such as volcanic eruption, erosion, and weathering
includes processes that deal with non-living things
deals with the different geographical evolutions
energy flows through an ecosystem
geological processes deal with..
money and trade
land - volcanic eruption, erosion, and weathering
non- living factors - heat and temperature
biomes
how is economics and ecology linked
economics is concerned with human interactions based on money and trade; in both, organisms and humans are trying to meet their needs
economics are concerned with human links and both, include the needs and wants of organisms
they both are talking about abiotic and biotic factors
they both are in the biosphere and all of the organisms interact with eachother
what are the levels of organizations
individual, population, ecosystem, and biosphere
population, biome, system, town
sunlight, temperature, humidity, soil
individual, population, community, ecosystem, biome, biosphere
what are some examples of abiotic factors
sunlight, temperature, humidity, soil types
all living parts of the ecosystem
nonliving factors - plants and animals
both nonliving and living factors
what are the 3 modern methods ecologists use
observation, experimentation, and modeling
observing, recreating, and producing
training, evolving, and developing
how do primary producers make their energy
they absorb the sunlight and chemically convert it into forms of living cells
they use the three modern methods - observation, experimentation, and modeling
they transfer the sunlight and chemically absorb it into forms of living cells
they contain the sunlight and chemically convert it into forms of living cells
list of consumers
carnivore, herbivore, omnivore, scavengers, decomposers, ad detritivores
carnivore , decomposers, omnivore, scavinger
detritus, decomposers, omnivore, scavengers, carnivore, herbivore
what are decomposers
organisms that breaks down and obtains energy from dead organic matter
organisms that obtain and transfer energy from dead organic matter
organisms that feed on plants and animal remains
organisms that help in the production of energy
detritivores produce detritus
true
false
what are detritivores
organisms that feed on plant and animal remains and other dead matter
organisms that breaks down and obtains energy from dead matter
organisms that eat both plants and animals
organisms that feed on plants
how does energy flow in a food chain
energy flows through an ecosystem in a two way stream, from primary producers to various consumers
energy flows through an ecosystem in one way stream, from primary producers to various consumer
energy flows through an ecosystem from secondary consumers
energy flows from the ecosystem in a wave-like pattern
