Biology: Energy Production and Trophic Levels

These flashcards cover key vocabulary related to energy production, processes, and biological classifications regarding producers and consumers.

Producer

An organism that makes its own food.

Heterotroph

An organism that must consume other organisms for energy.

Photosynthesis

The process where plants convert light energy into chemical energy (glucose).

Chemiosmosis

The movement of hydrogen ions across a membrane to create ATP (energy).

Chemoautotroph

An organism that makes food using energy from chemical reactions (not sunlight).

Photoautotroph

An organism that uses light to produce its own food (plants, algae).

Energy Pyramid

A diagram showing energy decreasing as you move up trophic levels.

Primary Consumer

An organism that eats producers (herbivore), such as a rabbit.

Example of Producer

Grass and algae are examples of producers.
