I would think so. At night plants consume a small amount of carbon dioxide, to supplement the energy that they get from the light during the day. But don't worry, they only consume a small fraction of the amount of oxygen they produce throughout the day.
So I would say yes they do consume oxygen in the dark.
No, plants need oxygen for respiration during the dark phase of photosynthesis. They produce more oxygen than they use but, they still need to have oxygen.
In the dark, plants stop using carbon dioxide for photosynthesis as there is no sunlight to drive the process. Instead, they mainly respire by taking in oxygen and releasing carbon dioxide during cellular respiration.
Plants take in carbon dioxide from the atmosphere to use in the dark reactions (Calvin Cycle) of photosynthesis, and oxygen is released into the atmosphere as a byproduct of photosynthesis.
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.
Oxygen is a bi product of living plants. As the plant during light hours takes in co2 it releases oxygen. During the dark hours the plant does not use co2 but uses oxygen and produces co2.
All animals and plants. Plants use oxygen as well as carbon dioxide.
They expire it.
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.
Oxygen is the gas that animals use in respiration. Plants use both oxygen and carbon dioxide. (This is assuming you mean cellular respiration.)
