Answer:
In this relationship , the role of wolves is as Secondary Consumers .
Step-by-step explanation:
A PRODUCER - Producers are referred to as an organism that prepares its own food. Often, they are called autotrophs.
- All the green plants, for example.
A DECOMPOSER -: Decomposers are organisms which break down organisms and waste that are dead or decaying. Their function is ecologically important as they recycle the nutrients through a natural biological process (decomposition).
- Fungi and bacteria that derive their nutrients from dead plant or animal matter are examples of decomposers.
PRIMARY CONSUMERS -: Typically, primary consumers are herbivores-animals that eat plants. Since they have to eat other items to survive, they are called heterotrophs. This is different from farmers who make their own food and are autotrophic.
- Insects, mice, and deer are common examples of this type of product.
SECONDARY CONSUMERS -: The secondary consumers are species that eat energy from the primary consumers. Only other animals eat carnivores, and omnivores both eat plant and animal matter.
- You can find secondary users, such as dogs , cats, moles, and birds, in temperate areas , for example. Foxes, owls, and snakes are other examples. Examples of secondary consumers that receive their energy from primary consumers by scavenging are wolves, crows, and hawks.
In the given foodchain , the wolves are consuming beavers as their food and beavers consume leaves , branches and twigs as their food. Therefore , it is cleared from the above definations , that leaves and branches consumed by the beaver are producers(as they are the part of plants ) , the beavers are herbivores dependent on green plants , so they are primary consumers and the wolves who are preying on beavers are secondary consumers as they are carnivores .
Hence, the correct answer is OPTION D.
