Producers
- Photosynthetic organismsare theproducersof biomass for life on Earth
- They produce their own food using energy from the Sun
- A producer has the following特征:
-
- They are at thestartof everyfood chain(the first trophic level, which is always the biggest)
- They canphotosynthesise(producers are normally green plants or algae)
- They makeglucoseby photosynthesis
- They use this glucose to produce other biological molecules, which then make up the producer’sbiomass(some of the glucose produced is also used in respiration to release energy for the cell)
- In extreme environments (such as underwater volcanic vents) the producers are not photoautotrophs but chemoautotrophs who produce organic molecules without using energy from the Sun)
