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.
Most bryophytes such as mosses, differ from all other plants in that they lack true leaves and roots.
All bryophytes are very small and commonly grow in moist shaded areas in the hills. They complete their vegetative phase on land but water is necessary for their sexual reproduction. In addition bryophyte are non vascular plant and they lack cuticle and stomata.
Natural resources are the things that are present in nature right now. Ecosystem capital is when corporations use those resources to make a profit; profit meaning to sale things for an unreasonable amount.
Good luck!
