100

Places where carbon is stored for either long or short periods of time

Carbon Reservoirs

100
What are the 2 names for the first producers of energy-rich compounds that are later used by other organisms.
What is primary producers and autotrophs.
100
What is the difference between a food chain and a food web?
Food chains are steps that show transfer of energy through organisms by eating and being eaten in one single chain. Food webs are interacting food chains all linked together. (many food chains are in one food web because most organisms eat more than one thing)
100
What are the 4 biogeochemical cycles (how elements pass from 1 organism to another)?
What is biological process, geological process, chemical and physical process, and human activity. In biogeochemical cycles matter can be recycled/changed. (know about these processes)
100
What do decomposer do to contribute to food webs?
Decomposers convert dead remains to detritus (stuff detrivores eat) and during that process release nutrients that primary producers use to make energy.
200

Small pieces of dead and decaying plant and animal remains.  These organisms eat this material

Detritus, Decomposers

200

What are the two main types of energy that primary producers use and the processes that correspond with them?

What is sunlight and chemical energy; photosynthesis and chemosynthesis.

200

What is the name of the primary producers consisting of the mixture of floating algae and attached algae?

What is phytoplankton. This is eaten by small animal plankton called zooplankton

200
What are the 3 Nutrient Cycles that pass necessary nutrients through the biosphere?
What is Carbon cycle, nitrogen cycle, and phosphorus cycle. (know these)
200

Which nutrient cycle does not cycle through the atmosphere?

Phosphorus Cycle

300

The largest reservoir of this is in the atmosphere; The largest reservoir of this is in the hydrosphere.

Nitrogen (78% of air we breathe); Carbon

300
What are the 2 names for the organisms that rely on other organisms for energy and nutrients to survive?
What is consumers and heterotrophs.
300
What is a trophic level and how does it relate to ecological pyramids?
What is each step in a food chain or food web. It relates to ecological pyramids because ecological pyramids (there are 3 different types) show the relative amount of energy/matter in each trophic level.
300
What is the 1 cycle that does not pass on necessary nutrients like the other 3 cycles and what does it pass on?
What is the Water cycle. It passes on water (can enter the atmosphere through evaporation or transpiration)
300

A process by which bacteria obtain energy by converting nitrates into nitrogen gas which is released into the atmosphere

Denitrification

400

Name one human activity that affects the carbon cycle.

Extraction and burning of coal, oil and natural gas; production of concrete; clearing and burning forests.

400
What are the 6 different types of consumers?
What is carnivores, herbivores, omnivores, decomposers, detrivores, and scavengers.
400
What are the 3 different types of ecological pyramids?
What is pyramid of energy, pyramids of biomass, and pyramid of numbers. PYRAMID OF ENERGY show the amount of energy available at each trophic level. PYRAMID OF BIOMASS show amount of living matter at each level. PYRAMID OF NUMBERS show number of organisms at each level in an ecosystem.
400

Any nutrient whose supply limits productivity is called this.  Plant growth can be limited by a short supply of one or more nutrients (Name two)

Limiting nutrient.    Options: Nitrogen, Phosphorus and Potassium
400
The total amount of living tissue within a given trophic level is
What is biomass
500

What drives the exchange of carbon dioxide between the atmosphere and hydrosphere?

Photosynthesis and Cellular Respirator

500
What is taken in and produced during photosynthesis?
What is carbon dioxide and oxygen
500
What happens to energy as it goes through the Pyramid of Energy?
Most of the energy is stored or used while 10% is passed on to the next trophic level
500
What is the difference between the movement of energy and nutrients?
Energy flows in one-way while nutrients can be recycled, used, stored, and changed.
500

This is a process by which bacteria can convert nitrogen gas into ammonia

Nitrogen fixation
