The interactions and relationships in a given area within living components and between living components and non-living components.
What is an ecosystem?
100
Nitrogen gas (N2) in the atmosphere is converted into ammonia (NH3) by nitrogen fixing bacteria.
What is nitrogen fixation?
100
Positions that organisms occupy in the food chain.
What are trophic levels?
100
The total number of individuals in a species in a given area.
What is population?
100
Factors that affect the population based on the density of that population.
What are density dependant limiting factors?
200
The living components within an environment.
What are biotic factors?
200
The process where producers, such as planets, take in carbon dioxide from the air and combine it with water and energy to make oxygen and glucose.
What is photosynthesis?
200
Organisms that make their own food from inorganic substances and sunlight.
What are producers?
200
The number of individuals living in a given area.
What is population density?
200
It causes acid rain, soot, air pollutants, and climate change.
What is fossil fuels combustion?
300
The area or natural environment in which an organism of population normally lives.
What is a habitat?
300
All living cells take in oxygen and combine it with glucose to produce energy for living. This process puts carbon dioxide back into the air and also produces water.
What is cellular respiration?
300
Organisms that eat other organisms to obtain energy.
What are consumers/heterotrophs?
300
Materials and energy, food chains, competition, and density.
What are the four main factors that determine carrying capacity?
300
The main impact of fertilizer overuse; leads to dead zones in the ocean.
What is eutrophication?
400
A diagram that represents how organisms obtain energy as they eat other organisms.
What is a food chain?
400
Protein from dead plants and animals are converted into NH3 by bacteria.
What is ammonification?
400
It llustrates the total chemical energy being passed along each trophic level.
What is an energy pyramid?
400
The maximum number of organisms of a particular species that can be supported by a particular ecosystem.
What is carrying capacity?
400
Carbon dioxide + energy + H2O = oxygen + glucose
What is the formula for photosynthesis?
500
The function or position of an organism or population within an ecological community.
What is a niche?
500
Nitrates (NO3) are converted into nitrogen (N2) which is then released into the atmosphere.
What is denitrification?
500
The build-up or increase in toxin concentration associated with trophic level increase.
What is biaccumulation?
500
The percentage or number of individuals of a given age in that population.
