HideShow resource information

Respiration

The equation is

Glucose + oxygen -> arbon dioxide + water + engery

1 of 7

Photosynthesis

The equation is

Carbon + water --sunlight--> glucose = oxygen

2 of 7

Combustion

The equation is

Fossil fuel/ wood + oxygen -> carbon dioxide + water

3 of 7

Photosynthesis 2

Photosnythesis takes carbon from the air and combustion puts it back in the air

detritus feeders

  • Eats dead organisms
  • Produces their own waste material
  • E.g. Maggots, worms
5 of 7

Decompers

  • Break down dead organic matter into its basic constituents ( enuymes)
  • Bacteria
  • Fungi
6 of 7

Best conditions for most microorganisms (and there

  • Warmth - speeds up chemical reations
  • Moisture - easier to dissolve food; prevent mirobes from drying out
  • Many need oxygen to repire
