Here is an example of what the pyramid looks like. The grass in the food pyramid is the Producer. The grasshopper in the food pyramid is a Primary Consumer. The frog in the food pyramid is a Secondary Consumer, because it eats the Primary Consumer (the grasshopper).
What is food chain and its types?
Food chain is the relationship between the individuals that constitutes a linear chain. In a food chain of an ecosystem, energy flows from one trophic level to another. There are 2 types of food chains, namely Grazing food chain and Detritous food chain.
