Question

a typical ecosystem like the one pictured here might have 200,000 caterpillars, 10,000 frogs, 500 snakes, and 35 owls . why do you think there are fewer and fewer organsims at each level of the food chain

Answer 1

Answer:

Food chain in an ecosystem is defined as the passage of food from one trophic level to the next higher trophic level. The transfer of food from one trophic level to the next level results in the passage of energy through these trophic levels. In a Grassland food chain, the initial organisms are grass. They are producers which produces food using solar energy. Grasshopper are primary consumers. They eat plants. They are herbivores. Frogs are secondary consumers. They eat grasshopper. They are carnivores. Snakes are tertiary consumers. They are carnivores and eat frogs. Eagles are Quaternary consumers. They are carnivores and eat snakes.

Thus, the correct answer is 'Grass → Grasshopper → Frog → Snake → Eagle.'
