How do autotrophs and heterotrophs benefit one another within an ecosystem? A. Autotrophs produce oxygen and carbon dioxide for heterotrophs, which produce chemical energy for autotrophs.

B. Autotrophs synthesize ATP and other nutrients for heterotrophs, which produce oxygen for autotrophs.

C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.

D. Autotrophs transform chemical energy into radiant energy for heterotrophs, which fix carbon for autotrophs.

Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. what can be inferred from these observations? monarchs must threaten and attack birds, but not wasps. monarchs have a way of discouraging bird predation that does not involve hiding. monarchs’ wings are so colorful that most birds must find them difficult to eat. monarchs lay more eggs than other less conspicuous butterflies.
