Discover the intricate relationships that define animal interactions in diverse ecosystems such as forests, rainforests, tundras, saltwater, freshwater, and deserts. This overview explores the concepts of mutualism, parasitism, commensalism, scavenging, predator/prey dynamics, decomposition, and competition. Learn how various species interact, compete for resources, and contribute to the balance of their ecosystems, from bees pollinating flowers to the vital roles of scavengers and decomposers.
