Biotic & Abiotic Biotic  Frog, Tree, Grass, Fish, Mosquito, Snail, Bird, Lilly pad, Bacteria, Weeds, Abiotic  Oxygen, Soil, Light, Rock, Pollution, Temperature, Glass, Sand, Plastic, Pipe

What is in each ecosystem?  The study of all living things would be a huge task so we break things down into smaller pieces  kBRGvyw kBRGvyw

Species  Species – a group of organisms so similar to one another that they can breed and produce fertile offspring. e.g., one single mosquito

Population  Population – a group of individuals that belong to the same species and live in the same area. e.g., all the crows in an area

Community  Community – A group of several populations living in a defined area. e.g., all the frogs ducks, water lilies
