Ashark eats a penguin that has recently been feeding on some krill. the penguin has 100 joules worth of energy, but the shark ultimately gains only about 10 joules. where does the rest of the energy go? it is destroyed and cannot be recovered. it was used by the penguin as it tried to get away from the shark. it is used for cell functions or transformed to heat energy. it reverts back to the krill that the penguin ate.

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
