Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.

Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria. Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.

There are four different types of heterotrophs which include herbivores, carnivores, omnivores and decomposers.

There are two types of heterotrophs: photoheterotroph and chemoheterotroph. The first uses light for energy but not carbon dioxide for their carbon source, but must rely on compounds such as carbohydrates, fatty acids, and alcohol (non-sulfuric bacteria, etc.).

There are three types of heterotrophs: are herbivores, carnivores and omnivores.

It is easy to see how humans are chemoheterotrophs! We eat food every day. That food is made from animals, plants, and other organisms. We break down the organic chemicals from their cells to both obtain our own energy, and building materials for our own bodies.

A giraffe is a heterotroph.

Consumers are also called Heterotrophs.

: requiring complex organic compounds of nitrogen and carbon (such as that obtained from plant or animal matter) for metabolic synthesis — compare autotrophic.

Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers. Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms.

Moss is both a producer and a decomposer. Moss is considered both a producer and a decomposer because it produces its own food through photosynthesis and helps to break down organic matter into nutrients.

Frog does not prepare its food by itself and depends on other organisms for food ,so it is a consumer.

Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds.

Mosses are non-flowering plants which produce spores and have stems and leaves, but don’t have true roots. Mosses, and their cousins liverworts and hornworts, are classified as Bryophyta (bryophytes) in the plant kingdom.
