Lemurs’ bodies are adapted to efficiently store energy for times when food is scarce. This adaptation may help to explain how le
Brums [2.3K]

Answer: Lipids.

Explanation:

The large carbon -hydrogen bonds(C-H) in chains of lipids makes them ideal storage of energy.

T<u>he more C-H bonds breakage, the higher protons availability from Citric acid cycle NADH and FADH2  and hydrogen atom splitting (to protons and electrons) for  the electron transport chains (ETC</u>), and therefore the higher proton pumps for  more ATP's synthesis in the mitochondria matrix.  

In addition large number of electrons  surrounding carbon atom in fatty acids than other food molecule is added factor.  The transfer of these electrons to oxygen during oxidation of fatty acids releases large amount of energy (9 kilo calorie) into the cells,  more than other food substances

F. Why are there more producers in the world than top carnivores?
Rainbow [258]

Answer:

There is only enough food for a few top level consumers

Explanation:

The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer. Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.
