Arthropods are the most diverse phylum in the animal kingdom.they have jointed appendages and an exoskeleton containing chitin.they may be segmented into head and truck, head, thorax and abdomen or cephalothorax and abdomen.they tend to shed of their exodkeleton during the process of metamorphosis . examples of arthropods include ticks, cockroaches
Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.
