What will happen to life on Earth in the absence of photosynthesis answer?

What will happen to life on Earth in the absence of photosynthesis answer?

In the absence of photosynthesis there would not be any food and oxygen for the survival of living organisms and the life would be impossible on the earth.

What would happen if photosynthesis did not exist?

If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth’s atmosphere would eventually become nearly devoid of gaseous oxygen.

What would life on Earth be like without plants?

Without plants, animals would have no oxygen to breathe and would die. People also depend on plants for food. All animals eat either plants or plant-eating animals. Without plants there would be no food to eat!

Do you think that photosynthesis is necessary for life to exist on earth explain?

Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. The importance of photosynthesis in our life is the oxygen it produces.

Can you image life on earth in the absence of photosynthesis?

Ans. No, we cannot imagine life on earth in the absence of photosynthesis. In the absence of photosynthesis there would not be any food. Besides, oxygen which is essential for the survival of all living organisms is produced during photosynthesis.

Can life be possible without photosynthesis?

If there was no photosynthesis, plants and animals likely could not exist. In addition the atmosphere would have very little oxygen because photosynthesis releases a large amount of oxygen into the air. Otherwise, the Earth would be a pretty barren lifeless place without photosynthesis.

How does photosynthesis make life on Earth possible?

Photosynthesis sustains life on Earth today by releasing oxygen into the atmosphere and providing energy for food chains. The rise of oxygen-producing photosynthesis allowed the evolution of complex life forms like animals and land plants around 2.4 billion years ago.

Can you survive without plants Why or why not?

Humans and animals use the oxygen (O2) in the air for their energy process and produce CO2 as waste. A plant derives energy from the CO2 and produces O2 as waste. If there were no plants on the planet we wouldn’t be able to breathe.

Is life possible on Earth without plants Why?

Not possible. Life on Earth depends on plants, algae and fungi. For humanity, all seven billion of us, they are the major source of food, clothing, shelter and medicine.

What is the usefulness of photosynthesis for those living on the Earth?

Photosynthesis is the main source of food on earth. It releases oxygen which is an important element for the survival of life. Without photosynthesis, there will be no oxygen on earth. The stored chemical energy in plants flows into herbivores, carnivores, predators, parasites, decomposers, and all life forms.

How does life on Earth depend on photosynthesis?

Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).

Do you think it is possible for a certain living things can live with the absence of oxygen?

(Your cells can do anaerobic respiration but it is not efficient enough to keep you alive in the absence of oxygen)….d. Oxygen gas (O2) was absent from the early Earth.
