Which of the following is not true concerning the flow of energy through an ecosystem? a. most solar energy is used in photosynthesis. b. photosynthesis and cellular respiration are performed by plants. c. not all solar energy is used for photosynthesis. d. most of the energy from photosynthesis flows out as heat. select the best answer from the choices provided

D the organisms at the bottom of the chain collect the most energy at 90% and the rest get only 10% going up

Explanation:

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

it has one origin of replication, but it proceeds in two directions - d)
