The food chain of a producer is the sun, the primary consumer, the secondary consumer and the decomposer. The producer uses the sun and nutrients in the soil to make food, and animals that consume it eventually die and fertilize the soil.Continue Reading
The first step in the food chain of a producer, such as a plant, is using the soil and sun to make its own food. Soon, a primary consumer, usually an herbivore or insect such as a bison or grasshopper, eats the producer. These primary consumers are then eaten by secondary consumers, such as a spider in the case of the grasshopper. Sometimes the food chain consists of long lines of consumers. For instance, a shrew feeds on a spider before a weasel eats the shrew, and a red-tailed hawk captures the weasel before a great-horned owl preys on the hawk. These animals that are higher up on the food chain are tertiary consumers.
These consumers eventually die for various reasons, and their bodies are broken down by decomposers, such as bacteria and fungi. The nutrients return to the soil, and the plants absorb those nutrients when making food. In some cases, plants die before another organism consumes them, and they decompose right away rather than passing their energy up through the food chain.Learn more about Zoology
Plankton exist near the bottom of the ocean's food chain and provide nutrition for whales, shrimp, snails and jellyfish. Plankton also play an important role in the carbon cycle by removing inorganic carbon dioxide due to photosynthesis.Full Answer >
Instead of viewing the prey cycle as a linear food chain, it is helpful to view predator and prey relationships in the tropical rainforest as an interconnected food web. The predatory cycle in the tropical rainforest is complex as the rainforest is home to many different types of organisms, from tiny insects to large cats and birds of prey.Full Answer >
The bald eagle's food chain consists of aquatic plants and diverse grass types as primary producers. Insects, mice, different sizes of fish, frogs and smaller birds occupy the primary, secondary and tertiary consumer roles. The bald eagle, having no real predator, resides at the top of its food chain.Full Answer >
No animal eats anaconda snakes, as this predator is on top of the food chain. Anacondas are in danger of being exterminated by humans, who kill them either out of fear or for commercial purposes, for the snakes' skin.Full Answer >
