What is law of constant proportion class 9th? The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in […]
Why do reaction forces exist?
Why do reaction forces exist? The reaction force is what makes you move because it acts on you. Newton’s Third Law of Motion explains that forces always come in action-reaction pairs. The Third Law states that for every action force, there is an equal and opposite reaction force. This is the reaction force. What is […]

What is the role of carbon dioxide in photosynthesis and in cellular respiration?
What is the role of carbon dioxide in photosynthesis and in cellular respiration? Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other […]
Why electric flux is zero in a closed surface?
Why electric flux is zero in a closed surface? If there is no net charge within a closed surface, every field line directed into the surface continues through the interior and is directed outward elsewhere on the surface. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric […]
What are three ways to show how energy flows through an ecosystem?
What are three ways to show how energy flows through an ecosystem? Key Points Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it. Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic. Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules. Why […]
