Options

A. Thermodynamics
B. Biogenetic
C. Kinetic energy
D. Potential energy

Answer

To solve the question regarding the study of energy transfer and relationships between all living organisms, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that describes the study of energy transfer and relationships among living organisms.

2. **Identifying Key Concepts**: We need to focus on concepts like ecosystems, energy flow, food chains, and the interactions between different organisms.

3. **Defining Ecosystem**: An ecosystem is a structural and functional unit of nature where living organisms (plants, animals, microbes) interact with each other and their environment.

4. **Energy Flow in Ecosystems**: Energy transfer occurs in ecosystems through food chains and food webs, where energy flows from producers (like green plants) to various levels of consumers (herbivores and carnivores).

5. **Trophic Levels**: The different stages in a food chain are called trophic levels. Energy transfer happens in a unidirectional manner, starting from producers to primary consumers and then to higher-level consumers.

6. **Energy Transfer Efficiency**: It is important to note that only about 10% of the energy from one trophic level is passed to the next level, while the rest is lost as heat or used for metabolic processes.

7. **Conclusion**: The study of these energy transfers and relationships in ecosystems is referred to as **thermodynamics** in biological contexts.

### Final Answer:
The study of the energy transfer and relationships between all living organisms is known as **thermodynamics**.
