ecosystem definition
a community (multiple species living in the same area), including the abiotic elements in that area
community definition
multiple species living in the same area
population definition
single species group
organism definition
an individual: plant, animal, fungi, etc
organ system definition
a system of multiple organs working together to perform a specific function
organs definition
a collection of tissues that structurally form a unit designed for a particular function
tissues definition
a group or layer of cells that work together to perform a specific function
cell definition
