Frequent question: What is the ultimate source of energy for most life on Earth?

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

What is the ultimate source of energy for most forms of life on Earth quizlet?

Sunlight functions as an ultimate source of energy for most forms of life on Earth.

What is the ultimate energy for all living things?

In all living organisms, the ultimate source of energy is the Sun.

What is the ultimate source of energy for photosynthesis group of answer choices?

Energy from the Sun fuels life on Earth

Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.

What are the two main sources of energy for all living things?

What does every food chain end with?

Detritivores and decomposers are the final part of food chains. Detritivores are organisms that eat nonliving plant and animal remains. For example, scavengers such as vultures eat dead animals.

What is the basic source of energy?

Primary sources can be used directly, as they appear in the natural environment: coal, oil, natural gas and wood, nuclear fuels (uranium), the sun, the wind, tides, mountain lakes, the rivers (from which hydroelectric energy can be obtained) and the Earth heat that supplies geothermal energy.
