They do not. All green plants make oxygen. Something else growing in there is using up oxygen.

What would happen in an ecosystem if there were more organisms that produce carbon dioxide than organisms that produce oxygen?
ecosystem,the sun hits the water and the algae grow.Algae produces oxygen for animals like fish , and provides food for microscopic animals .Absorb oxygen with their gills and expel CO2 which plants then use to grow.
How plants and people use oxygen?
Well people breath oxygen and plants use it in photosythesis
What do plants supply for us?
In a ecosystem, plants provide energy that is passed along the food chain, and oxygen through the process of photosynthesis.
Which gas is needed by plants for respiration?
Oxygen is the gas that animals use in respiration. Plants use both oxygen and carbon dioxide. (This is assuming you mean cellular respiration.)
What process do plant use to make sugar and oxygen and add carbon to an ecosystem?
photosynthesis
The ultimate source of all energy in a terrestrial ecosystem is?
most plants use the same amount of oxygen they produce. if animals use oxygen but do not produce, why haven't we run out of oxygen

How plants and people use oxygen?
Well people breath oxygen and plants use it in photosythesis
Which process uses oxygen in plants algae and animals?
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.
Do plants ever need to use oxygen?
Plants never need to use oxygen because its their waste product.
Who are the users of oxygen?
All animals and plants. Plants use oxygen as well as carbon dioxide.
What living things use oxygen?
Humans and animals use oxygen to breathe. Plants exhale oxygen.
What do plants supply for us?
In a ecosystem, plants provide energy that is passed along the food chain, and oxygen through the process of photosynthesis.
How do plants use Oxygen?
They expire it.
Why do most plants and animals need oxygen to survive?
Although plants to use oxygen, they emit unneeded oxygen into the atmosphere. This helps to replenish oxygen supplies for other organisms.
Do animals and plants have blood to carry oxygen?
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.
Does the decay of plants create a major source of oxygen?
No, bacteria or insects that eat plants use oxygen and the dead plants, which contain carbon, release carbon not oxygen.
