Answer;

The above statement is false

Explanation;

Photosynthesis is the biological conversion of light or electromagnetic energy from the Sun into chemical energy. It occurs in green plants, algae, and some types of bacteria, and requires a series of biochemical reactions.

In photosynthesis, carbon dioxide and water react with one another in the presence of light and a chemical known as chlorophyll to produce a simple carbohydrate and oxygen.

Fossils of what are thought to be filamentous photosynthetic organisms have been dated at 3.4 billion years old. Geological evidence suggests that oxygenic photosynthesis, such as that in cyanobacteria, became important during the Paleoproterozoic era around 2 billion years ago.

Describe an experiment to show that pressure acts in all directions in liquids.​
boyakko [2]

We frequently observe kids playing with polythene bags filled with water that have little holes drilled into them at various locations so they can sprinkle water on other kids. Through this experiment, we can say that pressure acts in all directions in liquids.

<h3>Liquid's pressure</h3>

Since both liquids and gases may flow, they are both referred to as fluids. Fluids under rest pressure behave uniformly in all directions.

Weather forecasts can be made using barometers. They track the evolution of atmospheric pressure throughout time.

On weather forecast maps, pressure variations appear as an isobar pattern. Predictions are made using these changes in pressure, and they are fairly accurate when combined with wind observations.

<h3>Pressure and depth in liquids</h3>

As you go away from a liquid's surface, pressure rises. for instance: A bucket has three holes that are all the same size. Since there is more pressure at the bucket's bottom, the water spills out more forcefully. Dams are thicker at the bottom for this reason.

lidiya [134]
<span>Solar energy arrives and is converted into chemical energy by plants which is eaten by animals and converted again and the animal is either eaten by another animal or dies and is broken down by decomposers and the energy is converted back into basic elements for plants to feed off of with the help of solar energy hence the cycle starts again

sorry this is all i know i hope it helps</span>
