A
- Utility Principle
- Judaic-Christian Ethics
- ‘Mother Earth’ Principle
2
Q
Name the 5 different components of energy flow in ECOSYSTEMS:
A
A) Producers B) Consumers C) Decomposers D) Food chain E) Food pyramids
3
Q
Energy in ecosystems:
Discuss the Producers.
A
- Solar energy (radiant energy) into potential chemical energy
- Autotrophic organisms
–ability to convert radiant energy into energy-rich organic compounds by means of photosynthesis using anorganic food source - Who:
– Blue-green bacteria
– Algae
– Mosses
– Ferns
– Seed/flowering plants
4
Q
Energy in ecosystems:
Discuss the Decomposers.
(Know the concept, not the detail)
A
- Who: Bacteria & fungi
- Heterotrophic, known as saprophytes
- Responsible for the decomposition process in organic compounds
- The process yields inorganic substances, which serve as a nutrient pool for producer
PRODUCER -> CONSUMER -> DECOMPOSER -> PRODUCER
They stand in specific relation to one another, thereby forming a food chain
5
Q
Energy in ecosystems:
Discuss the Consumers.
A
Animals split into 3 groups
- > Herbi - Primary consumers (plant-eater)
- > Carni - Secondary = Eat herbi, Tertiary = Scavenge
- > Omni - Eat everything
