Part 1
Who started the idea of natural selection- organic evolution?
Charles Darwin
what is considered competition within the same species
intraspecific competition
term used to classify cycle in which elements, chemical compounds, and other forms of matter are cycle from one organism to another
Biogeochemical cycles
the greatest number of individuals the environment can support over a long period of time is known as
carrying capacity
what are the four biomolecules
carbs, lipids, proteins, nucleic acids
What is considered an abiotic factor AND give an example
nonliving; temp, ph, sunlight
Define autotroph.
An organism that can produce its own food
Burning of fossil fuels, oil, coal and natural gas, has increased the amount of carbon dioxide (CO2) in the atmosphere and reduction of vegetation which means less plants to use the carbon dioxide is known as what
carbon cycle
Temperature and weather are known as what kind of factor (not abiotic or biotic)
density independent factors
cell, tissue, organ, organ system, organism
changes solar energy into chemical energy
photosynthesis
A relationship where one organism benefits and the other is not harmed or benefitted
commensalism
when there is a large input of a limiting nutrient in aquatic ecosystems this can result in an immediate increase in the amount of alfeo known as this
this type of behavior is genetically determined
innate behavior
what is negative feedback and give an example
bringing the body back to homeostasis; sweating, insulin production
What percent of energy is transferred from trophic level to trophic level
10%
relationship where both organisms benefit
mutualism
What is the common number of links in a food chain? think about the trophic levels
Four
this is described as a new beginning; a location that has never been colonized before is is known as
primary succession
childbirth, blood clotting, fruit ripening, ice melting, lactation are all examples of what
positive feedback
This is a system of interconnected food chains within an ecosystem
food web
this type of species causes ecological or economic harm. What is the type of species?
invasive species
What process occurs when plants take in water through roots and release oxygen and take in CO2 through stomata in their leaves
transpiration
this type of species colonizes a location that is barren or has previously been damaged
pioneer species
what are the products of photosynthesis
glucose and oxygen
