trophic level

use your book to define each vocabulary term.
energy
thermodynamics

metabolism
photosynthesis

cellular respiration

adenosine triphosphate

Explanation:

• trophic level: The position an organism occupies in a food chain, food web, or ecological pyramid, based on its feeding relationships (e.g., producers, primary consumers, secondary consumers).
• energy: The capacity to do work or cause change; it exists in various forms (e.g., kinetic, potential, chemical) and is essential for biological processes.
• thermodynamics: The branch of physics (and relevant to biology for energy flow in organisms) that deals with the relationships between heat, work, energy, and the transfer of energy. The two main laws relate to energy conservation and entropy.
• metabolism: The sum of all chemical reactions occurring in an organism, including catabolic (breaking down) and anabolic (building up) processes to maintain life, grow, and reproduce.
• photosynthesis: The process by which green plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce glucose (chemical energy) and oxygen, converting light energy to chemical energy.
• cellular respiration: The process by which cells break down glucose (or other organic molecules) in the presence (aerobic) or absence (anaerobic) of oxygen to release energy in the form of ATP, with carbon dioxide and water (in aerobic) as byproducts.
• adenosine triphosphate (ATP): A molecule that stores and transfers energy within cells; it is often called the "energy currency" of the cell, releasing energy when the terminal phosphate group is removed (converting to ADP).

Answer:

• trophic level: Position in food chain/ web based on feeding.
• energy: Capacity to do work/ cause change.
• thermodynamics: Study of energy relationships (heat, work, etc.).
• metabolism: Sum of all chemical reactions in an organism.
• photosynthesis: Process to make glucose/ O₂ from light, CO₂, H₂O.
• cellular respiration: Process to break down glucose for ATP energy.
• adenosine triphosphate: Energy - storing/ transferring molecule in cells.
