Energy in most ecosystems must flow through autotrophs because ______.
The energy value listed for foods refers to the _______.
Ecosystem productivity is principally limited by _______.
Which of the following is not true concerning the flow of energy through an ecosystem?
When sunlight strikes Earth, approximately _______.
Which of the following is not a direct fate of the energy flowing through photosynthesis?
Which of the following is not true about energy in ecosystems?
What percentage of a lower trophic level’s energy flows to the next higher trophic level?
Which individual would be the safest from a lightening strike?
Explain why lightning strikes can be dangerous even when an individual is not directly struck.
Lightning strikes are dangerous whether an individual is or is not in the path of the discharge. The current propagated by a lightning strike is actually what is harmful and the current can pass through the ground after striking. This means that even near-misses can be dangerous as the current travels through the ground.
Which individual would be the safest from a lightening strike?

Which of the following best describes the fate of energy in ecosystems?
Energy in most ecosystems must flow through autotrophs because ______.
Explain why energy in most ecosystems must flow from the sun, then to autotrophs and finally to heterotrophs, in that order.
Most of the energy in ecosystems enters as sunlight, so it is the principal source of energy for the biosphere. Autotrophs are organisms that can convert sunlight, solar radiation, into chemical energy that they and other organisms can use. Heterotrophs cannot utilize sunlight directly to make their food, so energy can only flow to them after passing through autotrophs.
Heterotrophs convert solar energy into chemical energy.
