They expire it.
For starters, algae are plants. Plants never use oxygen. Animals use oxygen in the process of respiration. Decomposers use oxygen in the process of respiration when decomposing plants and animals including algae.
Plants never need to use oxygen because its their waste product.
All animals and plants. Plants use oxygen as well as carbon dioxide.
Well animals do but plants don't. Plants don't actually really use oxygen- they give it out. They use the sunlight and Carbon Dioxide in photosynthesis and the by-product (what they give out) of this is Oxygen.
We breathe in oxygen and breathe out carbon dioxide. Plants take in this carbon dioxide and release oxygen, which we use after that.
plants
Oxygen is the gas that animals use in respiration. Plants use both oxygen and carbon dioxide. (This is assuming you mean cellular respiration.)
oxygen
Plants use oxygen during cellular respiration to generate energy for growth and reproduction. People use oxygen to break down food molecules and produce energy through cellular respiration, allowing our cells to function properly. Both plants and people rely on oxygen as a critical component in their metabolic processes.
they are alike because in photosynthesis plants create oxygen. cells use the oxygen that plants produce in cellular respiration to get cells oxygen.there for it makes a cycle. plants produce oxygen,cells take oxygen,we produce carbondioxide, plants use carbon dioxide in photosynthesis.
They do not. All green plants make oxygen. Something else growing in there is using up oxygen.
The gas that plants and animals use, which is essential for respiration, is oxygen. Oxygen is produced during the process of photosynthesis in plants, where carbon dioxide is converted into glucose and oxygen using sunlight, water, and chlorophyll. This oxygen is then released into the atmosphere and utilized by both plants and animals for their metabolic processes.
