Too Close for Comfort?
A tick feeding on a deer, for example.
What is parasitism?
Coal, sediment, CO2, photosynthesis, cellular respiration
What is the carbon cycle?
These are able to fix their own carbon; most use sunlight.
What is a producer (or autotroph)?
Using this process of changing sunlight into usable chemical bond energy, cyanobacteria oxygenated the world.
What is photosynthesis?
Most lakes, ponds, and rivers usually have less than 1% salt.
What is fresh water?
A zebra eating grass, for example.
What is a predator-prey interaction?
Precipitation, water vapor, surface water, groundwater, percolation, oceans, evaporation
But don't use the word "water".
What is the hydrologic cycle?
They have a means of digesting something else for energy and most nutrients.
What is a consumer?
A population of mice eat a total of 10,000 kcal of energy. The owl received 1,000 kcal of energy total from eating all of the mice.
What is the 10% Rule?
Another word for ocean ecosystems.
What is marine?
Coral and dinoflagellate algae, for example.
What is mutualism?
These store carbon for tens of thousands to millions of years as limestone, oil, and coal.
What is a carbon sink?
This process recycles dead organic matter and waste in either the soil or water.
What is decomposition?
In this cellular process, the chemical bond energy of sugar is changed into chemical bond energy in ATP. CO2 is another product of this reaction.
What is cellular respiration?
The amount of salt in an aquatic ecosystem.
What is salinity?
There is limited space on the rocky intertidal seashore for mussels, limpets, and barnacles, for example.
What is competition?
N2, NH4, NO3-, NO2-
The atmosphere, water, soil, living things
What is the nitrogen cycle?
This is a complex network of predators and prey in an ecosystem.
What is a food web?
This is equal to the Gross Primary Productivity minus the energy for respiration.
What is Net Primary Productivity?
The cloudiness of the water in an ecosystem.
What is turbidity?
Honeybees making a hive in a tree hollow, for example.
What is commensalism?
Never in the atmosphere, the main source is rocks.
What is the phosphorus cycle?
This is a strategy in which closely related organisms maximize the available nutrients in an ecosystem, each having evolved specialization.
What is resource partitioning?
Police and judges won't enforce this law that states that, in a closed system energy can't be created or destroyed, but can be changed in its form.
What is the First Law of Thermodynamics.
Temperature, salinity, pH, turbidity, dissolved gas levels are this type of factor in an ecosystem.
What are abiotic factors?
