Which factor can decrease the rate of a chemical reaction?
Illusion [34]

(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.

How temperature effects the rate of a chemical reaction

Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.

Plants and other producers make their food using photosynthesis<br> True<br> False
quester [9]

Answer:

True

Explanation:

Producers are unique set of organisms that begins a food chain or web. They are not dependent on any other organism for energy source (autotrophs). This is because of their ability to capture light energy from sunlight and use it to power the process of making their own food called PHOTOSYNTHESIS.

Photosynthesis is a unique feature of all autotrophic organisms like plants, planktons etc. It involves the use of an inorganic source (CO2) to synthesize organic food in the presence of sunlight. Plants and other producers obtain energy directly from the sun, hence, they are called PRODUCERS because they start a food chain in an ecosystem. Other organisms called CONSUMERS rely on them for energy.
