The 3 main things that photosynthisis needs to occur is water sunlight and dirt
(correction) its water (H2O) carbon dioxide (CO2) and energy from the sun (photons)
The equation is 6 CO2 + 6 H2O+ sunlight energy → C6H12O6(glucose)+ 6 O2
The most important product of the light reaction in plants for humans is oxygen. During photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Oxygen is released into the atmosphere as a byproduct of this process and is essential for human respiration.
I'm assuming you're talking about animals, but I apologize if I'm incorrect. :) Oxygen is the most important substance to a living thing - One can survive a few days without water, a few weeks without food, but only a few minutes without oxygen.
Most plants are vascular plants.
The most important things in prefab homes are efficient design, quality materials, and skilled construction. Efficiency in design helps maximize space and energy usage, while quality materials ensure durability and sustainability. Skilled construction ensures proper assembly and installation of the prefab components for a safe and long-lasting home.
Best Answer - Chosen by Voters Animals and plants both synthesize fats and proteins from carbohydrates; thus glucose is a basic energy source for all living organisms. The oxygen released (with water vapor, in transpiration) as a photosynthetic byproduct, principally of phytoplankton, provides most of the atmospheric oxygen vital to respiration in plants and animals, and animals in turn produce carbon dioxide necessary to plants. Photosynthesis can therefore be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their metabolic processes.
it provides food and most important the oxygen
Insects are the most abundant animal on the planet, and they do many important things for Earth, such as pollinating plants and decomposing dead plants and animals.
Most plants release some oxygen from atmospheric carbon dioxide.
The two things produces by plants that would be important to keep astronauts alive on a long journey would be glucose and oxygen. Oxygen is most important.

The two important things that plants provide for the living world are oxygen and food. Plants are responsible for the presence of oxygen which is needed for most organisms on the planet. Plants are also a source of food, whether directly (vegetables and fruit) or indirectly (eating what ate the plants). Without plants humans would not exist.
it was important because they could make things.
Oxygen is the most important factor for living things.
water
Plants and animals
Yes, most plants need carbon dioxide.
