Through simple diffusion
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.
The breakdown of food without the use of oxygen is called anaerobic respiration. This process produces energy in the form of ATP without requiring oxygen. However, it generates lactic acid or ethanol as byproducts, depending on the organism carrying out the process.
An organism that requires oxygen for its survival and metabolism is called an aerobic organism. These organisms rely on oxygen to produce energy through aerobic respiration.
Three resources every organism needs from its habitat are nutrients, water, and somthing to breathe.
food water space or shelter oxygen
They provide oxygen, shelter and food for the organisms

The circulatory system brings oxygen and food to the cells of an organism. It is made up of the heart, a network of vessels and the blood.
Anerobic respiration
An organism needs some source of food and must intake oxygen to be considered alive.
e placenta refers to the organ that permits food and oxygen to reach the developing organism.
Living organisms that produce oxygen and food that animals need are called producers. For example, plants are producers because they make their own food.
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.
An organism's habitat provides food, shelter, and resources such as water and space that are necessary for survival. It also offers protection from predators and harsh environmental conditions. The habitat influences the organism's behavior, reproduction, and overall well-being.
The breakdown of food without the use of oxygen is called anaerobic respiration. This process produces energy in the form of ATP without requiring oxygen. However, it generates lactic acid or ethanol as byproducts, depending on the organism carrying out the process.
For an organism to do photosynthesis the organism must have Chloroplast. The only organisms that can do photosynthesis are plants.
