life could not exist on without trees because they produce most of oxygen that humans and wildlife breathe . Trees absorb co2 from the atmosphere and release o2 using the process of photosynthesis.
Why would there be no life on Earth 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!
Why are green plants necessary for life on Earth?
Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves , which humans and other animals need to breathe. Living things need plants to live – they eat them and live in them. Plants help to clean water too.
What would happen to an ecosystem without green plants?
When green plants make food, they give off oxygen. This is a gas that all animals need to breathe in order to stay alive. Without plants, animals would have no oxygen to breathe and would die .
What would happen if all green plants were eliminated?
Answer: a) Green plants are the sources of food and energy for all organisms. If all green plants disappear from the earth, all the herbivores will die due to the absence of food and so will the carnivores. ... If plants give out carbon dioxide it is also possible that there is no breakdown of carbon and water.
Can plants exist without humans?
No, plants can't survive without animals or humans . In terms of energy balance, they can survive. Energy balance in the sense (Photosynthesis and respiration are balanced). There is no depletion in the reservoir of carbon dioxide and oxygen also.
How long would we survive without plants?
However, because there are no plants, animals would have to eat each other. By my calculations, the time for the population to die out would be 5023.3 days, or 13.75 years . So we would run out of food long before we ran out of breathable air, and life on Earth would rapidly collapse within our lifetimes.
How does watering plants help the environment?
Transpiration is the process by which water evaporates from plant pores, cooling the environment via evaporative cooling. ... Plants also stabilize the soil through their roots, which bind soils, and through their leaves, which keep raindrops from eroding soils.
How trees are important for us?
Trees are vital. As the biggest plants on the planet, they give us oxygen, store carbon, stabilise the soil and give life to the world's wildlife . They also provide us with the materials for tools and shelter.
How do plants affect humans?
Flowers and ornamental plants increase levels of positive energy and help people feel secure and relaxed. Keeping flowers around the home and in the workplace greatly reduces a person's stress levels. ... People who keep flowers in their home feel happier, less stressed, and more relaxed.
What will happen if all plants are creepers?
Both creepers and climbers are weak-stemmed plants and, hence, cannot grow erect without support. The difference is that creepers spread horizontally along the soil . At the nodal regions – where leaves grow – they produce fibre-like roots arising from the base of the stem, which get fixed and grow further.
What will happen if there are no trees on Earth?
Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe . Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. ... Forests act as giant air filters for the world.
What happens if there are no green plants on the Earth Class 7?
Green plants are the sources of energy for all organisms. ... So, if all the green plants disappear from the earth, all the herbivores will die due to starvation and so will the carnivore, i.e., it would result in extinction of life from the earth.
What would happen if green plants disappear from Earth class10?
If all green plants will disappear from earth then it will cause a decrease in the concentration of the oxygen to such a low level , and high carbon dioxide concentration that it would not be possible for all the living organisms for breathing. Thus, it will result in their death.
Are there any place on the earth where there are no plants?
There is one part of the world where nothing thrives, however: the Atacama Desert in Chile .
What will happen if all animals eat only plants?
All animals eat either plants or plant-eating animals. Without plants, there would be no food to eat . So, both the options are correct, but the immediate consequence of the absence of plants would lack of oxygen. If there is no oxygen, there would be no photosynthesis and hence, no food.
