<h2>Energy </h2>
Explanation:
Energy flows in only one direction through an ecosystem
- The Sun supports most of Earth's ecosystems
- Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
- The food energy created by producers is passed to consumers, scavengers, and decomposers
- Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
- Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
- So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
- Animals at the third level have only 10% as much available to them as those at the second level

Concepts in anatomy from the given options include:
- The brain is composed of two hemispheres.
- Each kidney contains approximately 6-10 pyramids.
- The muscle on the back of the arm has three heads of origin.
- Study of form.
<h3>What is anatomy?</h3>
Anatomy is a branch of biology that is concerned with the study of the structure of living organisms and their various parts.
Anatomy studies the position of body structures as well as the position of related structures or organs of the body.
Anatomy also studies how the structure of these body parts relates to their functions.
Therefore, concepts in anatomy from the given options are:
- The brain is composed of two hemispheres.
- Each kidney contains approximately 6-10 pyramids.
- The muscle on the back of the arm has three heads of origin.
- Study of form.
In conclusion, anatomy deals with structure of body parts of living organisms.
