Question 8: What will happen to an ecosystem if:
a. All producers are removed;
b. All organisms of herbivore level are eliminated; and
c. All top carnivore population is removed
Answer:
- As all the green plants are autotrophs they play important role as the source of energy for all the heterotrophs because heterotrophs are dependent on the autotrophs. Green plants convert solar energy into the chemical energy for making the food source. If the plants get disappear from the earth it will lead to imbalance in the atmosphere. Primary productivity will be reduced and the producers that carry out respiration process which they carry out and break down some of the organic compounds to release chemical energy which they pass onto the herbivores. So if the producers are removed, there will be no energy available for the higher trophic level because the herbivores are dependent on the producer level and so on.
- Herbivores (those organisms which take organic food from the autotrophs, i.e., they are dependent on other organism for the food consumption) feeds on the green plants or producers. So if the herbivore level are eliminated from the food chain, primary productivity will increase.
- Carnivores are those which feed on the herbivores or the other organisms. Carnivores are the last trophic level in the food chain so, if the carnivore population is removed; the herbivores level will increased, overgrazing will occurs and there will be shortage of primary productivity. And, by the overgrazing of animals will leads to desertification.
