Answer:
1. 20 units
2. 4 units
Explanation:
In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.
If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.
Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.
The events that might triggered the to do more environmental movements include the effects of DDT on the environment and a river in Ohio was on fire because of the pollution present. It is a good thing though because, in the end, everything we do to the environment will have and will always have an effect on us living in this planet.<span />
