Thekey differencebetween detrital and grazing food chain is that碎屑食物链是一条食物链,始于死有机物作为主要能源的主要来源,而放牧食物链是一条食物链,始于绿色植物作为主要能源。
A food chain illustrates the feeding relationships betweenspeciesin abioticcommunity. There are two main types of food chains as grazing food chain and detrital food chain. Grazing food chains are based on光合作用plants. Therefore, green plants are the main source of energy in grazing food chains. Detrital food chains are based ondecomposers or detritivores. Hence, the dead remains of organisms are the main source of energy in detrital food chains.

什么是碎屑食物链?
分解剂或碎屑是以腐烂的有机物(死生物)为食的生物。基于碎屑的食物链称为碎屑食物链。分解剂主要是微生物,例如细菌和真菌。因此,碎屑食物链主要由微生物组成。
They decompose dead organic matter in the ground and participate in recycling organic matter in the environment. Detrital food chains are small compared to grazing food chains.
What is a Grazing Food Chain?
A grazing food chain is a food chain that begins with a producer or a photosynthetic plant. Therefore, grazing food chains are based on green plants. The first trophic level is a producer in the grazing food chain. The next level is a herbivore, and other levels can be occupied by an omnivore or carnivore.
Generally, grazing food chains are larger. These food chains release energy to the environment. Energy is released from plants to plant-eating animals and then into other animals. An example of a grazing food chain is shown below.
Grass ⇒ Rabbit ⇒ Wolf ⇒ Tiger
What are the Similarities Between Detrital and Grazing Food Chain?
- 碎屑和放牧的食物链是两种类型的食物链。
- There are at least three trophic levels in a food chain.
What is the Difference Between Detrital and Grazing Food Chain?
一个食物链,始于死亡的有机物is known as a detrital food chain. A food chain that begins with a green plant is called a grazing food chain. So, this is the key difference between detrital and grazing food chain. Decomposers are the first trophic level of a detrital food chain, while a green plant is the first trophic level of a grazing food chain. Generally, a grazing food chain is larger than a detrital food chain. Moreover, a detrital food chain mostly consists of microorganisms. But in contrast, a grazing food chain consists of macroscopic organisms. Thus, this is another difference between detrital and grazing food chain.

概括– Detrital vs Grazing Food Chain
There are two types of food chains as detrital and grazing food chain. A detrital food chain mostly consists of decomposers or microorganisms, and the main source of energy of a detrital food chain is the dead remains of organisms. A grazing food chain is based on photosynthetic plants. Therefore, plants are the main source of energy in grazing food chains. Generally, grazing food chains are larger than detrital food chains. Moreover, grazing food chains can have herbivores and carnivores. Thus, this summarizes the difference between detrital and grazing food chain.
