Consider a food chain in which grass is the producer having energy 5000 kcal and deer received 500 kcal of energy after eating the grass. Calculate the transfer efficiency.
Answers
Answer:
When energy is passed in an ecosystem from one trophic level to the next, only ten percent (10%) of the energy will be passed on. We can consider a typical food chain in the environment. It can be written as follows. Sun -----> Green Plants -----> Insects -----> Frogs -----> Snakes. The sun provides the energy that is used by the green plants. The green plants are the primary producers for the food chain. The energy from the sun is converted by the plants into food. The insects are the primary consumers. They are the first animals to eat the plants. When they eat the plants and obtain some of the energy (10%) they stored when making food. The rest of the energy is lost and dissipated as heat. Insects are eaten by frogs. The frogs are the secondary consumers in this food chain. They obtain part of the energy stored by the insects. The remaining energy stored by the insects is lost
