His study would include all BUT which levels in the structural hierarchy of life "organs"
<h3>Further explanation
</h3>
Ecologists study the interrelationships between organisms and their environments. Organs are the body's recognizable structures that perform specific functions. It is made of several types of tissue and therefore several types of cells. Some organs examples are the heart, lungs, liver, eyes, and stomach
In biology and ecology, abiotic components are non-living chemical and physical parts of the environment that affects the living organisms and ecosystems functioning. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Whereas the biotic factors are living or once-living organisms in the ecosystem. It is obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
The growth of a bacterial population occurs in exponential manner for example one cell gives rise to 2 cells, then 4 cells, then 8 cells, then 16, then 32, and so forth.
Human body life processes are maintained at several levels of structural organization. These includes the chemical, cellular, tissue, organ, organ system, and organism level.
