Classify the following specimens into major groups and subgroups: Cowpea, Cockroach, Earthworm, Mushroom, Toad, Pine, Amoeba, Tilapia. Discuss the ecological importance of the Earthworm.

Right Pretty~Nelly, let's go. a) Here are the classifications for each specimen: A. Cowpea: Major Group: Angiospermophyta Sub Group: Dicotyledoneae Common Name: Cowpea B. Cockroach: Major Group: Arthropoda Sub Group: Insecta Common Name: Cockroach C. Earthworm: Major Group: Annelida Sub Group: Oligochaeta Common Name: Earthworm D. Mushroom: Major Group: Fungi Sub Group: Basidiomycetes Common Name: Mushroom E. Toad: Major Group: Chordata Sub Group: Amphibia Common Name: Toad F. Pine: Major Group: Coniferophyta Sub Group: Coniferae Common Name: Pine G. Amoeba: Major Group: Protozoa Sub Group: Sarcodina Common Name: Amoeba H. Tilapia: Major Group: Chordata Sub Group: Osteichthyes Common Name: Tilapia b) Specimen C is the Earthworm. Earthworms are highly beneficial to the environment, particularly in soil ecosystems. They aerate the soil by creating burrows, which improves water penetration and allows plant roots to grow more easily. They also decompose organic matter by ingesting dead plant material and other detritus, breaking it down into simpler nutrients. Their castings (feces) enrich the soil with essential nutrients, making them more available for plants. This process enhances soil fertility and structure. c) Here is a simple dichotomous key to separate specimens B, C, D, E, and F: 1a.
