Detailed explanation-1: -A food web is a model of feeding relationships in an ecosystem. When an organism is eaten, the matter and energy stored in its tissues are transferred to the organism that eats it. The arrows in a food web represent this transfer.
Detailed explanation-2: -An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.
Detailed explanation-3: -A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
Detailed explanation-4: -ENERGY FLOW MODELS:-The energy flow models link the trophic levels with each other showing the inputs and losses of. energy at each trophic level. Lindeman (1942) was the first to propose such model assuming that. plants and animals can be arranged into trophic levels and the laws of thermodynamics hold for plants.
