Why does the crabeater seal have the carbon atom of a minke whale when it doesn’t eat minke whales? it’s related to something about the food chain, I think it might be that the decomposers break down the body of the minke whale and the crabeater seals eat what eats the decomposers

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
