What will happen if the grasses are removed from an ecosystem?

• Herbivores will not be able to survive

• Less energy will become available for organisms at higher trophic levels.

• The primary consumers will increase in number.

• More energy will be stored in the tissues of consumers and other organisms.

How much energy is usually transferred from one trophic level to another?

• 10%

• 20%

• 50%

• 100%

Which of the following is not true about energy flow in the ecosystem?

• Only 10% of the energy is transferred to the next trophic level.

• The decomposers absorb majority of the energy in the ecosystem.

• The sun is the ultimate source of energy in the ecosystem.

• The energy in the ecosystem flows in a one-way direction.
