What are Heterotrophs known as ?

Answers

Answer:

An organism that doesnt not produce its own food

Explanation:

Heterotrophs are consumers who eat other organisms for food, while autotrophs or producers make food by process of photosynthesis.

Answer:

A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.”

Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. 

Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.

Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms. Each food chain consists of three trophic levels, which describe an organism’s role in an ecosystem. Occupying the first trophic level are autotrophs, such as plants and algae. Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level. 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. Detritivores play an important role in maintaining a healthy ecosystem by recycling waste. Examples of detritivores include fungi, worms, and insects.

summarize how enzymes are made. (3 points)

Answers

Explanation:

The chemical reactions involved in photosynthesis are controlled by enzymes . As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate.

Enzymes are biological catalysts - they speed up chemical reactions. The reactions of photosynthesis, and many other biological processes, are controlled by enzymes.

Enzymes are required for most of the chemical reactions that occur in organisms. These reactions occur in the breakdown of chemical molecules, which we see in the digestive system.
