what do agricultural biologists do

what do environmental biologists do
work to prevent living things from going extinct

what do biologists in bioengineering do
study living systems to design mechanical devices

made up of one or more cells, displays organization, grows and develops, reproduces, responds to stimuli, requires energy, maintains homeostasis, adaptations evolve over time
list the levels of organization in order
