Tertiary consumers are carnivores that devour other carnivores. Apex predators have no predators and are at the top of their food chain. They include lions, tigers, wolves, and bears.
Secondary consumers eat primary producers (plant and animal life) for secondary consumers (insects, mollusks, and worms). Primary consumers are consumed by secondary consumers which in turn are eaten by tertiary consumers. This is a three-level hierarchy with tertiary consumers at the bottom.
Tertiary production refers to production not needed by primary or secondary consumers. Examples include wood produced by trees for their own growth as well as feces produced by animals for defecation. Tertiary consumers either recycle this material into the ecosystem through decomposition or remove it by scavenging. In very small populations, individuals may consume themselves to death (rarefaction).
Fourth level consumers are referred to as "detritivores". They derive their name from a needling mechanism used by some plants to inject toxins into competing organisms. Detritivores such as insects and spiders eat these plants and then excrete the seeds and pods within them. These particles become trapped on land and water surfaces where they germinate or attract more insects which carry them away for digestion.
These often ingest main consumers as well as other animal stuff. Carnivores are animals that eat meat. Examples include lions, snakes, and cats. The fourth level is referred to as "tertiary consumers." These animals depend on their prey's predecessors for food. They do not consume every part of their prey; instead they digest the bones, teeth, and other hard parts.
Tertiary consumers include humans. We depend mainly on carnivores for food, but we also eat plants and drink water. Although most carnivores eat meat, some species such as primates and dolphins are omnivorous--they will eat both plants and meat.
Level 5 animals are called "quaternary consumers." These animals feed on the tertiary consumers. For example, leopards eat smaller carnivores; bears eat trees and other plants; and people eat vegetables and fruits.
Quaternary consumers include insects. There are many different types of insects consumed by different animals. Some animals avoid certain insects by flying far away from their habitat or using strong smells or colors to scare off predators. However, this isn't possible for small creatures like insects that can't fly or hide away. They must be eaten.
In conclusion, no, there is no level 6 animal because levels 1 through 5 are all that exist.
A tertiary consumer is a human being. Because both secondary and tertiary consumers must search for food, they are referred to as predators. Primary producers are organisms such as plants that can grow without consuming other organisms. They make their own food by photosynthesis.
Although we do not directly eat plants or animals, we do consume their output - in this case, secondary consumers - to survive. Humans are unique in that we can decide what role we will play as consumers. Some people choose not to consume any products derived from animals, while others take an active role in trying new foods and buying local when possible.
Secondary consumers include animals. In order to live, animals must eat, and they obtain this food either by hunting or by eating other animals. Animals at each level of the food chain reduce the amount of energy available for higher-level animals by eating those below them. For example, when animals hunt larger animals, they tend to kill only the largest individuals because these are the most likely to provide a sufficient meal. Smaller animals risk being eaten if they try to flee or fight back because they are more vulnerable to attack.
Primary consumers include plants.
