The hydroponic method involves growing the tomatoes in a nutrient solution which contains all of the essential elements.
The practise of growing plants without the need for soil is known as hydroponics. Flowers, herbs, and vegetables grown hydroponically are planted in inert growing material and are then given nutrient-rich solutions, oxygen, and water throughout the growing process. The use of this technique results in accelerated growth increased yields, and improved quality. When a plant is growing in soil, the roots of the plant are always looking for the nutrients it needs to survive in order to provide for the plant's needs. If the root system of a plant is provided with direct access to water and nutrients, the plant does not need to expend any energy in order to maintain its own life. It is possible to focus the energy that the plant's roots would have spent obtaining food and water toward the growth of the plant instead. As a direct consequence of this, the development of new leaves and the blossoming of fruits and flowers are both stimulated.

Answer:An increase in light intensity causes both pupils to contract (see iris) even if only one retina is directly stimulated. This is known as a consensual reflex. Conversely, a decrease in light intensity causes dilation of the pupils

Answer:
Atmosphere, plant, animals, fossil fuels.
Explanation:
Carbon Is the essential elements needed for life.
Carbon cycle is the movement of carbon from the atmosphere to the Earth.
Carbon move in the carbon cycle and start from the atmosphere.
In the atmosphere, carbon react with oxygen and it is inform of carbon dioxide. Plants use the carbondioxide along with water,and uses light energy from the sun to produce carbohydrates through a process of photosynthesis.
Animals get carbon from plants after consuming plants.
During respiration, carbon atoms are released to the atmosphere.
Some human activities like burning of fossil fuels releases carbon to the atmosphere.
