An example of a terrestrial food chain is grass-grasshopper-snake-hawk. A food chain is a series of interconnected feeding relationships among different species in an ecosystem.Know More
Another example of a terrestrial food chain is plants-grasshopper-scorpion-fox. Different land habitats consist of different terrestrial food chains. The different levels in the food web are called trophic levels and represent the flow of energy and nutrients from the bottom of the food chain to the top. Animals at a higher level eat animals that are at a lower level. However, herbivores like grasshoppers eat plants.
Primary producers, which include plants, are at the bottom or base of the food web. While the grasshopper is an example of a primary consumer, a scorpion is a secondary consumer. The hawk, which is called a tertiary consumer, is at the top of the food web.
Another type of food chain in an ecosystem can be the marine food chain.
