Some of the explanations are based on the text book.
1. Population, made up of all organisms of the same species that live an area at the same time. You could also check the sources that I listed below.
2. Respiration, plants, some bacteria, algae, fish, and other organisms need oxygen for respiration.
3. Chemical Energy, during photosynthesis, producers convert light energy into the chemical energy in sugar molecules.
4. Decomposers, helps recycle once-living matter by breaking it down into simple, energy-rich substances.
5. Both a and b, plants & animals because plants use it directly from the soil and animals use it by consuming plants.
6. Decreases, as you move up the pyramid, the transfer of energy is less efficient and each level becomes smaller.
7. Estuary, is not a freshwater ecosystem but if your confuse about swamp, take a look at this source, http://wiki.answers.com/Q/Is_a_swamp_a_freshwater_ecosystem …
