What process allows autotrophs and heterotrophs to use energy?
photosynthesis
Most autotrophs make their “food” through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.
Where do autotrophs and heterotrophs get energy for cellular activities?
Autotrophs are able to manufacture energy from the sun, but heterotrophs must rely on other organisms for energy.
How does a heterotrophic organism make energy available for cellular processes?
Heterotrophic organisms are those living things that can’t make their own food through the process of photosynthesis. They must find and ingest their nutrients either by eating food or by absorption. They receive important energy in this way.
Why both autotrophs and heterotrophs depend on photosynthesis?
Food is chemical energy stored in organic molecules. Food provides both the energy to do work and the carbon to build bodies. Because most autotrophs transform sunlight to make food, we call the process they use photosynthesis. Heterotrophs cannot make their own food, so they must eat or absorb it.
How do autotrophs and heterotrophs acquire carbon?
Heterotrophs and autotrophs are partners in biological carbon exchange (especially the primary consumers, largely herbivores). Heterotrophs acquire the high-energy carbon compounds from the autotrophs by consuming them, and breaking them down by respiration to obtain cellular energy, such as ATP.
What do autotrophs and heterotrophs depend on photosynthesis to obtain energy?
Autotrophs depend on photosynthesis to get the energy(ATP & NADPH) by converting light energy from the sun into chemical energy in the form of organic compounds, which they need to survive. Heterotrophs can only obtain that energy by consuming an autotroph; which depends on photosynthesis.
How do autotrophs and heterotrophs depend on each other?
Autotrophs are organisms that are able to use a source of energy such as sunlight, to produce their own food. Heterotrophs depend on autotrophs to harvest energy from the sun. This energy is then passed on to heterotrophs in the form of food.
