What is the original source of energy in most ecosystems what would happen without this source?

What is the original source of energy for most ecosystems A grass b humans C the sun d heat?

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

What would happen to food chains of energy transformation was not possible?

Energy used in this way is converted into heat which is lost from the organism. No organisms can convert the heat energy back into chemical energy, and the hear is eventually lost from the ecosystem.

What is the original source of most energy in the biosphere quizlet?

What is the primary source of energy for the biosphere? Solar Energy is the primary source for all life on Earth. Process where plants produce chemical energy from water, carbon dioxide, and is activated by sunlight.

What is the original source of almost all the energy in most ecosystems A carbohydrates C water B sunlight D carbon?

The fundamental source of energy in almost all ecosystems is radiant energy from the Sun. The energy of sunlight is used by the ecosystem’s autotrophic, or self-sustaining, organisms (that is, those that can make their own food).

What is the original source of the energy that flows through most ecosystems Why must there be a continuous supply of energy into the ecosystem?

Solar energy is the original source of energy in most ecosystems. There must be a continual supply, due to energy only flowing in one direction in an ecosystem. Energy that is lost to heat must be replaced by more energy.

What is the original source of energy in fossil fuels?

The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.

What is the source of energy in most ecosystems animals plants oxygen sunlight?

The source of all energy in most ecosystems is the sun. This energy arrives in the form of sunlight, which is captured by organisms called producers. One example of a producer is a plant.

How does energy move through most ecosystems on Earth?

The Flow of Energy

Most ecosystems get their energy from the Sun. … Producers convert the sunlight into chemical energy or food. Consumers get some of that energy when they eat producers. They also pass some of the energy on to other consumers when they are eaten.
