Objective: Identify parts and function of body parts.
Habitat- Most live in mud around freshwater, some under water, and the majority in the soil
Predators- Humans, Raccoon, Armadillos, Chipmunks, & Monkeys.
Prey- Eat dead and decay animals.
Ecological Adaptation- Adaptations are bristly hairs on each segment, a body with no appendages, circular muscles in each segment, and pulls its food inside of the mouth area.
Trophic Level: Decomposer
Population Dynamics: Population dynamics of earthworm was significantly correlated with rainfall and physical characters of the soil.
Symbiotic Relationship: With Bacteria
Human Impact: Negative impact, humans are the main predator of earthworms.
Body system: To decompose dead and decay animals, break down dead organic matter and put them back to earth & finally organs help it decay the organic matter
