Using the diagram of the energy pyramid, which of the following statements are true? Select TWO correct answers. 

• Organisms at level 1 give direct energy to organisms in levels 2 and 4. 

• About 90% of available energy is lost from level 1 to level 2 as heat. 

• About 10% of available energy is directly gained from level 4 to level 3. 

• All organisms in the four levels receive energy from each other in a continuous cycle

Using the information in the energy pyramid, determine how many joules of energy the producers would have.

• 45630 Joules

• 456.3 Joules

• 45.63 Joules

• 4563 Joules

Select the tertiary consumers in the food web.

How does energy flows from the base to the top of the energy pyramid?

• Energy decreases as it moves up the pyramid because some is lost as heat at each level.

• Energy flows directly from the tertiary consumer back to the producers in a continuous cycle.

• Energy remains constant at each level, with no loss or gain.

• Energy increases as it moves up the pyramid because higher-level consumers require more energy.

True or False: Tertiary consumers do not receive all the energy level from the trophic level below them, because some energy is lost to the environment?

• True

• False

Which statement describes the importance of the water cycle?

• The water cycle only affects ocean water and has little impact on land ecosystems.

• The water cycle prevents water from evaporating, keeping the Earth's water supply constant.

• The water cycle removes all impurities from water, making it safe for consumption without filtration.

• The water cycle distributes and recycles Earth's water, sustaining all living organisms.
