Q

● Indicates the total amount of energy present in each trophic level.
● Shows the loss of energy from one trophic level to the next.
● Shows clearly that the energy transfer from one trophic level to the next is accompanied by a decrease due to waste and the conversion of potential energy into kinetic energy and heat energy.

Q

➢ made up of overlapping food chains
➢ Shows feeding connections; arrows illustrates energy transfer.

A

food webs

20
Q

➢ Producers have most available energy (sun).
➢ Energy is loft as it moves up through the food web;10 % rule- only 10% of the available energy is passed to the next trophic level.
➢ The “lost” energy is used to catch, eat and digest food.

A

ecological efficiency

21
Q

break down wastes and dead organisms.

A

decomposers

22
Q

➢ the pathway through which a substance is recycled.
➢any of the natural pathways by which essential elements of living matter are circulated.

A

Biogeochemical Cycles

23
Q

➢Enters ecosystem by precipitation; may infiltrate the soil ( be absorbed) or run-off into surface water.
➢Return the atmosphere by evaporation or transpiration (the loss of water in plants)

A

water cycle

24
Q

➢describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere.

A

carbon-oxygen cycle

25
Q

➢is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems

A

nitrogen cycle
