What is the flow of energy from the sun to heterotrophs?

Sun → Autotrophs → Heterotrophs → Environment → Space.

How does energy flow through heterotrophs?

Heterotrophs function as consumers in the food chain; they obtain energy in the form of organic carbon by eating autotrophs or other heterotrophs. Unlike autotrophs, heterotrophs are unable to synthesize their own food. If they cannot eat other organisms, they will die.

What is the pathway of energy flow from Sun to the organism?

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

How does energy from the sun flow to other animals food?

All nutritional energy comes from the Sun: plants use chlorophyll to photosynthesize the Sun’s energy into plant energy, and then animals either feed on plants for that energy or they feed on the animals that have eaten that plant energy. The food chain begins with the Sun and then the energy flows to producers.

How are heterotrophs and autotrophs dependent on the Sun?

They depend on energy from the sun in order to produce food. Heterotrophs depend on the sun’s energy indirectly. They produce organic substances from inorganic substances by using photosynthesis. They ingest organic substances and break it down into chemical energy.

Where does a heterotroph get its energy from?

There are two subcategories of heterotrophs: photoheterotrophs and chemoheterotrophs. Photoheterotrophs are organisms that get their energy from light, but must still consume carbon from other organisms, as they cannot utilize carbon dioxide from the air. Chemoheterotrophs, by contrast, get both their energy and carbon from other organisms.

How are photosynthetic autotrophs used to power life?

All life requires a constant input of energy. Only autotrophs can transform that ultimate, solar source into the chemical energy in food that powers life, as shown in Figure below. Photosynthetic autotrophs, which make food using the energy in sunlight, include (a) plants, (b) algae, and (c) certain bacteria.

How are carnivores and heterotrophs obtain food?

Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs. A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter.
