Answer:
A. Because energy is lost at every level.
Explanation:
energy decreases as it travels from lower levels to upper levels--which is a logical observation you could make.
Think of it like this--if a fish eats a small organism, it will then spend some of the energy obtained from the organism swimming around--so when a larger fish eats our fish, the energy from the original organism will already be partially lost (from our fish swimming around).
This means that when this pattern continues over multiple levels, we keep losing energy--which limits the environment's capacity for organisms to survive.
Hope this helps, have a lovely day :)
When a person see a cell with blue fills of varying lengths representing the values, the cells most likely have data bars applied to them.
<h3>What are Data bars?</h3>
Data bars are known to be a kind of conditional formatting that alters based on the data that is said to been shown.
The bigger the number, the fact still remains that the longer the bar that appears in a cell. They often do look like an advanced feature but they are said to be easier to input the data bars to a spreadsheet in Excel using few clicks.
