Which of the following is an example of a necessary chemical reaction in a living organism?
“Plants have the ability to trap and store energy from the sun” is the one that is an example of a necessary chemical reaction in a living organism.
What is the chemical reaction that plants use to break down sugar to make energy?
Which of the following are energy carrier molecules involved in photosynthesis?
Glucose and ATP. Two of the most important energy-carrying molecules are glucose and ATP (adenosine triphosphate). These are nearly universal fuels throughout the living world and both are also key players in photosynthesis.
How do organisms get the energy they need?
Organisms get the energy they need from food. A calorie is the amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius. Cellular Respiration is the process that releases energy from food in the presence of oxygen. Cellular Respiration produces Carbon Dioxide, Water, & Energy.
How do organisms obtain and use the matter and energy they need to live and grow?
A living organism can either make its food or depend on others to make food for them. For example, green plants produce their food from a process called photosynthesis. Other organisms eat green plants (which has a store of the energy they produce) to obtain energy. They are known as consumers or heterotrophs.
How do plants and animals get energy they need?
Most, if not all plants are producers, and they make their own food using sunlight and raw materials, through a process called “photosynthesis”. Plants get their energy in form of starch whereas animals get it in form of glycogen
How does matter behave in ecosystems?
Unlike energy, matter is recycled in ecosystems. In the figure below, you can see how (Figure below). Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots
What best describes the matter present in an ecosystem?
Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.
Is sedimentary a cycle?
sedimentary cycle The weathering of an existing rock, followed by the erosion of minerals from it, their transport and deposition, and their burial. The more sedimentary cycles a sediment has passed through, the more mature it will become and it will be dominated by well-rounded, resistant minerals.
What is the purpose of a biogeochemical cycle?
However, the biogeochemical cycles function to conserve and recycle the matter that is part of living organisms. There are several biogeochemical cycles on Earth including water, carbon, nitrogen, oxygen, phosphorous, sulfur and rock. A new cycle that is currently being studied by scientists is the mercury cycle
