Animals

Characteristics of Animals Eukaryotes (cells with nucleus) Multicellular – Cells Tissues Organs Organ systems Heterotrophs/Consumers – Herbivores – eat plants – Carnivores – eat animals Predator – the hunter Prey – the hunted – Omnivores – eat both plants & animals Most reproduce sexually Most can move at some point of their life
