Chapter 1: in terms of the hierarchical organization of life, a heart is at the __________ level of organization, whereas a human is at the __________ level of organization. *a) organ; organism: single organelle; organism, organelle; organ system, single tissue; multicellular organism, tissue; organism, organisms interact with their environments, exchanging matter and energy. For example, plant chloroplasts convert the energy of sunlight into: the energy of motion, carbon dioxide and water. *c) chemical energy: oxygen, kinetic energy, the material in tree trunks ultimately comes from, soil. *b) air: salt, animals, the lowest level of biological organization that can perform all the activities required for life is the, organelle. *b) cell: tissue, organ system, organism, in hypothesis-based science, deductive reasoning is used to predict a result that would be found if a particular hypothesis is correct. *a) true: false, a theory in science is equivalent in scope to a well-structured hypothesis, true.
