Plant obtain their food from the sun. The process is called photosynthesis. Animals obtain their food from animals or plants.
Animals inhale air in order to obtain the oxygen they use for extracting energy from food
Living things depend on organic matter for food and oxygen from the air or water they inhabit. Plants undergo photosynthesis to produce oxygen as a byproduct, and animals obtain oxygen through respiration.
people make food from farming and obtain food from animals
Animals without blood, such as sea sponges, obtain oxygen and nutrients through diffusion. They rely on their porous body structures to allow oxygen and food particles to diffuse in and waste products to diffuse out. This process occurs through direct contact with their environment.
Every animal breathes oxygen, even fish (they obtain it by the oxygen in the water).
from the food they eat.
they are carnivores so they get food by killing other mammals and oxygen by inhaling with there lungs
There is no oxygen. Animals need oxygen to breathe. Plus, no food or water.
Trees and other plants reserve a small fraction of oxygen produced from photosynthesis to convert their carbohydrates into energy. This differs from animals who eat food to obtain carbohydrates.
