This breaks down dead organisms into organic matter.
decomposer
what is considered competition within the same species
intraspecific competition
This cycle takes carbon dioxide from the atmosphere and then it is taken in from animals and expelled. The molecule in this cycle is also release from fossil fuels.
carbon cycle
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
This can occur if an organism from the food web is removed.
varies
An organism that can produce its own food
autotroph
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
This factor affects all populations regardless of their size.
density independent factors
cell, tissue, organ, organ system, organism
producers
A relationship where one organism benefits and the other is not harmed or benefitted
commensalism
deforrestation, minning, and agriculture contribute to this.
land pollution
The effect of this factor has on a population is reliant on the population's size.
Density dependent factors
This counteracts a change to bring a system back to homeostasis.
negative feedback
What percent of energy is transferred from trophic level to trophic level
10%
relationship where both organisms benefit
mutualism
Nonliving factors such as temperature, pH, rainfall is called this.
abiotic factors
A factor that causes the growth of a population to decrease.
limiting factor
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 organism causes ecological or economic harm due to it not originally being from the area.
invasive species
Carbon dioxide is considered this b/c it contributes to the warming of the earth.
greenhouse gas
The ability of a population of living species to increase under ideal environmental condition.
biotic potential
what are the products of photosynthesis
glucose and oxygen
