Ecology Test
What are the three Ecological Research Methods
Modeling, Observing, and Experimentation
Biodiversity
The VARIETY of Living things in an ecosystem
Detritivore
consume dead organic matter
Carbon cycle video
...
Food Chains and Food Webs model the flow of energy in an ecosystem
...
Heterotroph is another word for Consumer
...
Primary consumer eats the producers
...
Pyramids model the distribution of energy in and matter in an ecosystem
...
Consumer
A consumer gets its Energy from consuming other living things or something that was once living but now dead.
Population
A group of the same species living in the same area.
Trophic Level
A trophic level is the level of nourishment in a food chain
Hydrologic Cycle
Also known as the water cycle is the circular pathway in witch water cycles throughout the ecosystem specifically from the atmosphere, to the surface, below ground, and back.
Every Ecosystem has Living and non Living Factors (Flip)
An Ecosystem has Biotic and Abiotic factors, changing one factor in an ecosystem can affect many other factors.
Organism
An Individual living thing
what is another word for Producer?
Autotroph
Decomposer
Breaks down dead organic matter into simpler compounds. (they return vital nutrients back into the environment.
Community
Different Species that Live together in one area
Generalist
Eats a variety of species
Ecosystem
Includes all organisms and non living things such as, soil rocks, water, and climate.
Specialist
Is a Species that eats only one other species or a very small number of organisms.
Biome
Is areas with similar species and climate
Carbon cycle
LOOOK IT UP PG #390 the flow of carbon from the environment to living organisms and back again.
Biotic
Living (Plants, Animals, Fungi, Bacteria)
Key stone species
Make a big impact on the ecosystem for example, Beavers make damns.
Abiotic
Non Living (A means No or Non) Such as moisture, temp, wind, sun light, soil.
Ecologists Study environments at different levels of organization, What are these levels of Organization
Organism, Population, Community, Ecosystem, Biome (Remember OPCEB)
Omnivore
Organisms eating both animals and plants
Carnivore
Organisms eating only Animals
Life in an Ecosystem requires a source of energy (flip)
Producers Provide Energy for other Organisms in an Ecosystem, Almost all producers obtain Energy from sun light
Food chain
Shows a sequence of feeding relationships
Bio Chemical cycle
The movement of a particular chemical through the biological and geological parts of an ecosystem. Water can change from water to gas to ice.
Ecology is-
The study of relationships between Organisms and their Environment
Matter cycles in and out of an ecosystem
Water cycles through the environment and elements essential for life also cycles through the environment
Chemosynthesis
When a Producer creates its Energy from chemicals. (Minerals in water)
Producer
gets its energy from Abiotic Factors such as Sun light, (they make their own food)
Herbavore
organisms eating only plants
Food web
shows a complex network of feeding relationships
The biomass Pyramid compares (TALK TO RIZZI)
the biomass of different trophic level
Energy pyramid shows
the distribution of energy among trophic levels.
A Pyramid of numbers shows
the population of organisms at each trophic levels
