Because, by the process of photosynthesis plants produce oxygen which is most essential for humans, AND the plants provide food for their own survival and growth, and thus provide a food source for humans and many vegetation eating animals which are another food source for human life.

What organisms obtain food almost entirely by autotrophic photosynthesis?

Plants, algae, and some bacteria are organisms that obtain food almost entirely through autotrophic photosynthesis. They are able to convert sunlight into energy through the process of photosynthesis, using chlorophyll to capture light energy and produce organic compounds like glucose.


What process supports almost all life on earth?

Photosynthesis is a process that supports almost all life on earth. It is the process by which green plants, algae, and some bacteria convert light energy into chemical energy to produce food in the form of glucose, releasing oxygen as a byproduct. This process is vital for sustaining the majority of organisms on our planet.


What organisms supply almost all the energy for the rest of us?

Plants, such as green plants, algae, and some bacteria, are the organisms that supply almost all the energy for the rest of us through the process of photosynthesis. They capture energy from sunlight and convert it into chemical energy stored in molecules that other organisms can use as food.


Can cellular respiration happen without photosynthesis?

Yes, cellular respiration can occur without photosynthesis. Cellular respiration is the process by which cells generate energy from food molecules, while photosynthesis is the process by which plants convert sunlight into energy. Organisms like animals rely on cellular respiration to produce energy without needing photosynthesis.


What kingdom's organisms obtain food almost entirely by autotrophic phootosynthesis?

Organisms in the Kingdom Plantae obtain food almost entirely through autotrophic photosynthesis. They use sunlight, carbon dioxide, and water to produce their own food in the form of glucose, releasing oxygen as a byproduct.

Almost every oxygen molecule in the air was produced by photosynthesis?

That is correct. Photosynthesis is the process by which plants and other organisms convert sunlight into energy and produce oxygen as a byproduct. This oxygen is then released into the atmosphere, where it can be used by other organisms for respiration.

What is the ultimate source of energy for almost all organisms except those living deep in the ocean near a thermal vent?

The ultimate source of energy for almost all organisms is the sun. Through the process of photosynthesis, plants and other autotrophic organisms convert sunlight into chemical energy that is then consumed by heterotrophic organisms in the food chain.

What process do almost all living things depend on to supply them with energy?

Photosynthesis!


What type of organisms carry out photosynthesis?

Plants, algae, and some species of bacteria carry out photosynthesis. These organisms have chlorophyll, a pigment that allows them to capture sunlight and convert it into energy for growth and development. Photosynthesis is a crucial process for producing oxygen and organic compounds that sustain life on Earth.


Where does almost all of photosynthesis occur?

almost all photosynthesis occurs in plants


Is photosynthesis is the only way to balance oxygen in environment?

That is the major process. It generates almost every oxygen molecule


Importance of photosynthesis?

Photosynthesis is crucial for life on Earth as it is the process by which plants, algae, and some bacteria convert sunlight into chemical energy, producing oxygen as a byproduct. This process is the foundation of the food chain, providing energy for almost all living organisms. Additionally, photosynthesis helps regulate the Earth's atmosphere by removing carbon dioxide and releasing oxygen, contributing to a stable climate.


Where does almost all the energy used by living things come from?

Almost all the energy used by living things comes from the Sun, through the process of photosynthesis. Plants capture sunlight and convert it into chemical energy in the form of glucose, which is then consumed by other organisms, transferring the energy up the food chain.
