Explanation: Photosynthesis produces the energy that is the basis of the energy in an ecosystem. … Cellular respiration is the process by which the potential biochemical energy produced by photosynthesis is and utilized by the cells in plants and animals. Respiration produces Carbon Dioxide as a by product.
What is the role of photosynthesis in ecosystems?
It provides energy for nearly all ecosystems. By transforming light energy into chemical energy, photosynthesis provides the energy used by organisms, whether those organisms are plants, grasshoppers, wolves, or fungi.
What’s the role of respiration in an ecosystem?
The Purpose Cellular Respiration
Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.
What roles do photosynthesis and 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 organisms for cellular respiration.
What is the role of respiration?
The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
What is the role of photosynthesis in the ecosystem quizlet?
What is the role of photosynthesis and respiration in ecosystems? Photosynthesis (stores energy of biomass) and respiration (releases the stores of biomass) control the flow of energy. Process by which green plants convert light energy from the sun into chemical energy that is stored in organic matter.
Why is photosynthesis important for plants?
Photosynthesis is important to plants because it allows them to make glucose, which is needed to make energy and cellular structures.
What are the roles of photosynthesis and respiration in the global carbon cycle?
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
What is the role of photosynthesis in the carbon cycle?
During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures. This process forms the foundation of the fast (biological) carbon cycle. … In all four processes, the carbon dioxide released in the reaction usually ends up in the atmosphere.
What is the role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem?
The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen. … Cellular respiration releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment.
