Study Notes

Autotrophs and Heterotrophs

Chemoautotrophs are organisms that produce their own food using energy from inorganic compounds, an example being nitrifying bacteria.
The main difference between autotrophs and heterotrophs is that autotrophs produce their own food, whereas heterotrophs obtain their energy by consuming other organisms or organic matter.

Transport Mechanisms

The process called osmosis occurs when water diffuses into the cell and solute diffuses out.

Passive Transport Mechanisms

Simple diffusion is a passive transport mechanism that does not require ATP.

Essential Nutrients

The two types of essential nutrients are macronutrients, which are required in large amounts, and micronutrients, which are required in smaller amounts.
