Relationship Between Autotrophs and Heterotrophs by Maya Meow on Prezi
What is the relationship between a Producer, a Consumer, and a Decomposer? Producers may also be called autotrophs. like a Processor, who uses the raw materials, make some changes and market the product in an acceptable form. The definition of relationship marketing given in chapter 1 identified the building of relationships with customers as well as with other stakeholders, and it is these .

Ask a fellow entrepreneur to look at your social media postings and rate them for content, connection and consistency. The feedback can help you take your Know Like Trust Factor to a whole new level! Word of Mouth Referrals When it comes to owning your own business, word of mouth referrals are gold.
This is key to remember because customers rarely purchase products or services solely based on the products intended result. The answer includes all of the feelings and desires that come with that product and the results. By building your relationship marketing skills, you fulfill those additional needs. You provide more than just a product or service, you provide an experience.
To respond to a concern means that you find a way answer the question that empowers your company AND the person making the concern. Create Business Opportunities When you build your relationship marketing skills, you also open the door to more business opportunities because a personal connection experience leaves a a long-lasting impression.
That fond memory which you created with your customer will cause you to come to their mind more quickly and frequently. Because Mari had built a person-to-person connection, she was referred and her business took off. With a person-to-person relationship marketing model you can learn first hand, and at no cost to you, what your audience MOST desires.
For example, free Wi-Fi in Starbucks was a suggestion from patrons. Secondary consumers are generally meat-eaters—carnivores. The organisms that eat the secondary consumers are called tertiary consumers. These are carnivore-eating carnivores, like eagles or big fish.
Some food chains have additional levels, such as quaternary consumers—carnivores that eat tertiary consumers. Organisms at the very top of a food chain are called apex consumers.

We can see examples of these levels in the diagram below. The green algae are primary producers that get eaten by mollusks—the primary consumers. The mollusks then become lunch for the slimy sculpin fish, a secondary consumer, which is itself eaten by a larger fish, the Chinook salmon—a tertiary consumer.
In this illustration, the bottom trophic level is green algae, which is the primary producer. The primary consumers are mollusks, or snails. The secondary consumers are small fish called slimy sculpin. The tertiary and apex consumer is Chinook salmon.
For instance, humans are omnivores that can eat both plants and animals. Decomposers One other group of consumers deserves mention, although it does not always appear in drawings of food chains. This group consists of decomposers, organisms that break down dead organic material and wastes.
Decomposers are sometimes considered their own trophic level. As a group, they eat dead matter and waste products that come from organisms at various other trophic levels; for instance, they would happily consume decaying plant matter, the body of a half-eaten squirrel, or the remains of a deceased eagle.
Food chains & food webs
In a sense, the decomposer level runs parallel to the standard hierarchy of primary, secondary, and tertiary consumers.
Fungi and bacteria are the key decomposers in many ecosystems; they use the chemical energy in dead matter and wastes to fuel their metabolic processes. Other decomposers are detritivores—detritus eaters or debris eaters. These are usually multicellular animals such as earthworms, crabs, slugs, or vultures. They not only feed on dead organic matter but often fragment it as well, making it more available for bacterial or fungal decomposers.
When they break down dead material and wastes, they release nutrients that can be recycled and used as building blocks by primary producers. Food webs Food chains give us a clear-cut picture of who eats whom.
However, some problems come up when we try and use them to describe whole ecological communities. For instance, an organism can sometimes eat multiple types of prey or be eaten by multiple predators, including ones at different trophic levels.
This is what happens when you eat a hamburger patty! The cow is a primary consumer, and the lettuce leaf on the patty is a primary producer.Autotrophs and Heterotrophs
To represent these relationships more accurately, we can use a food web, a graph that shows all the trophic—eating-related—interactions between various species in an ecosystem. The diagram below shows an example of a food web from Lake Ontario.
Primary producers are marked in green, primary consumers in orange, secondary consumers in blue, and tertiary consumers in purple. The bottom level of the illustration shows primary producers, which include diatoms, green algae, blue-green algae, flagellates, and rotifers.
The next level includes the primary consumers that eat primary producers. These include calanoids, waterfleas, cyclopoids, rotifers and amphipods.
The shrimp also eat primary producers. Primary consumers are in turn eaten by secondary consumers, which are typically small fish.
