The answer to the question is 7.4%.
<h3>How to calculate production efficiency?</h3>
Energy from food is 5000 J
Energy lost in feces is 2300 J
Energy used in cellular respiration (metabolism) is 2500 J
The production efficiency of consumer in an ecosystem is given by
(Energy from food- Energy lost in feces-Energy used in cellular respiration (metabolism)) divided by (Energy from food- Energy lost in feces)
= (5000 - 2300 - 2500)/ (5000 - 2300)
= 7.4
<h3>What is
production efficiency?</h3>
Energy transfer efficiency from one trophic level to the next is referred to as ecological or production efficiency. It is determined by a variety of assimilation and resource acquisition efficiency for organisms within an ecosystem.
The average efficiency of energy transfer between trophic levels is such that net production at one trophic level is often only 10% of net production at the trophic level before it (the Ten percent law). In contrast to being absorbed for production by consumers, a sizeable quantity of energy is lost to the environment as a result of non-predatory mortality, egestion, and cellular respiration. Although these fractions differ significantly from ecosystem to ecosystem and from trophic level to trophic level, the picture roughly represents the fraction of energy available after each stage of energy loss in a typical ecosystem.

Answer:
The frozen ground does not allow roots for large trees to grow
Explanation: characteristic of *severe cold climate regions* *especially treeless artic regions* and high mountain tops. Plant life must adapt itself to a *short growing season(e.g,shrubs and low lying plants adapt themselves to short growing season)* of about 60 days and to a soil that remain frozen for most of the year. Most tundra regions are covered with bogs, marshes, ponds and a spongy mat of decayed vegetation, although high tundras may be covered with only lichens and grasses. Vegetation of dwarf woody plants, grasses, sedges and lichens may be quite profuse in tundra despite the thin soil and short growing season.
Therefore, large trees cannot allow roots for large trees to grow in frozen ground but short shrubs and low lying plants can,to an extent .
