Sustainability is the ability of the ecosystem to maintain its ecological processes, the composting of debris into soil, the exchange of carbon and air, the production of rainfall, photosynthesis, the life-giving processes required to maintain life as we know it on earth. By feeding on plants and on one another, animals play an important role … Marine ecosystems are regarded as the most abundant type of ecosystems … The carbon cycle is tied to the availability of other elements and compounds. Finally, ecosystems link us together culturally, as we share in appreciating the beauty of the outdoors through recreation, education, and spiritual uses. Cellular respiration and photosynthesis are opposite, but equal in a way. Which is the most correct statement about the role of photosynthesis in an ecosystem? It … Energy enters the system through photosynthesis and is incorporated into plant tissue. During the day, trees and plants absorb carbon dioxide for photosynthesis and give out oxygen. Glucose can then be converted into carbohydrates. Dim conditions will cause photosynthesis to slow down. While photosynthesis requires energy (in most cases, light energy) to occur, respiration releases energy. Half of all the glucose created by the plant is used in respiration to make energy available for cellular processes. The process of photosynthesis is crucially important to the biosphere for the following reasons: It creates O 2 , which is important for two reasons. Primary producers convert chemical energy to light energy b. Maitain the oxygen cycle in an ecosystem. The carrying capacity is a measure of how many individuals can a given ecosystem provide for. The more carbon dioxide (CO 2) plants and trees absorb during photosynthesis, the process they use to make food, the less CO 2 remains trapped in the atmosphere, where it can cause temperatures to rise. In the photlysis water oxygen is released in the atmosphere. 2. Without photosynthesis, the whole marine ecosystem will eventually suffers. Primary consumers rely directly on light energy c. Primary producers convert light energy to chemical energy as a service to the ecosystem, not for their own gain d. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. a. The ecosystem surrounding the vents has a diverse array of animals, such as tubeworms, crustaceans, and octopi that derive energy from the bacteria. The molecular oxygen in Earth’s atmosphere was created by photosynthetic organisms; without photosynthesis there would be no O 2 to support cellular respiration (see chapter … Iron fertilization is the intentional introduction of iron to iron-poor areas of the ocean surface to stimulate phytoplankton production. Supporting. The importance of photosynthesis is not just that it can capture sunlight’s energy. make their own food. power a chemical process and make organic molecules. The community of algae can be the precise habitat for the marine ecosystem. During photosynthesis, plants take carbon dioxide from the air and used it to make glucose (stored carbon), while releasing oxygen. The ocean ecosystems are an important source of atmospheric oxygen due to the vast population of autotrophic algae releasing oxygen through photosynthesis. The energy flow in the ecosystem is important to maintain an ecological balance. An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. As such, they help in the purification of the air that we breathe. These biotic and abiotic components are linked together through nutrient cycles and energy flows. A part of the energy is stored within the plants. Plants form the critical base of food chains in nearly all ecosystems. Ch._8_Short_Answer.pdf - Name Date AP\/College Biology Ch 8 Photosynthesis Short Answer Questions 1 What is the role of photosynthesis in the ecosystem 2 Sunlight keeps harmful bacteria from taking over aquatic ecosystems. Forests remove about 30% of anthropogenic CO2 emissions through photosynthesis and return almost 40% of incident precipitation back to the atmosphere via transpiration. The results of the study also highlight the importance of the role of ecosystems in the global carbon cycle. The interactive nature of the two is represented best … This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2) sequestration from the atmosphere.. Iron is a trace element necessary for photosynthesis in plants. Important Words Photosynthesis is when palnts use the sun for nuterients and food. Light is the most important of them all. Without it, photosynthesis is impossible. Photosynthesis is one of the most important contributors to numerous of things, ranging from maintaining the ecosystem stable to producing oxygen for the entire world. Importance Of Ecosystem An ecosystem can be defined as the biological community of living beings, communicating with the physical environment and other nonliving components. Photosynthesis is important to food chains because creatures capable of photosynthesis form the foundation of most food chains. Why is photosynthesis important to most ecosystems.
