A geothermal heating system is installed outside a house by laying pipes underground, as shown in the image. The heat is transferred from the ground to the pipes to keep the house warm. How does this system of heating the house reduce the impact on the natural environment? O by providing energy to the ground O by conserving underground energy O by using a sustainable source of energy O by transforming one form of energy to another 1 12:46 & backs 9. 8

In ecological systems, a rough rule of thumb is that when energyis transferred from plants to plant-eaters or from preyto predator, the efficiency is only about 10% (p. 72). Muchof this inefficiency is a consequence of the second law ofthermodynamics. Another way to think of this is that eating 1calorie of material from an animal is the ecological equivalentof eating 10 calories of plant material.Humans are considered omnivores because we can eat bothplants and animals. Our food choices have significant ecologicalimpacts. With this in mind, calculate the ecologicalenergy requirements for four different diets, each of whichprovides a total of 2000 dietary calories per day. How many ecologically equivalent calories would it taketo support you for a year, for each of the four diets listed?

In a pond ecosystem, mosquito larvae feed on photosynthetic algae. Other larvae, such as dragonfly larvae, feed on the mosquito larvae. The dragonfly larvae are, in turn, consumed by fish, whichcan be preyed upon by raccoons.How many different organisms in this ecosystem get their energy from the food they consume?1.
