Step 1:: Examine the diet of lions.
Lions are carnivores, which means they primarily consume meat from other animals. According to Table 1 on page 1, the main food sources for lions are various species of herbivores, such as zebras, wildebeests, and buffalos.
Step 2:: Analyze the macromolecules present in the food that lions eat.
From Table 2 on page 1, we can see the approximate macromolecule composition of the animals that lions consume. The majority of their diet consists of water (60 - 70%), followed by proteins (15 - 25%), and lipids (5 - 15%). Carbohydrates are present in very small quantities (1 - 3%).
Step 3:: Identify the macromolecule missing from the food that lions eat.
Based on the information from Tables 1 and 2, it is clear that carbohydrates are nearly absent from the food that lions consume. Therefore, lions do not rely on carbohydrates as their primary energy source.
Step 4:: Examine the diet of elephants.
Elephants are herbivores, which means they primarily consume plant material for their diet. According to Table 1 on page 1, elephants consume various types of vegetation, including grasses, leaves, bamboo, and bark.
Step 5:: Analyze the macromolecules present in the food that elephants eat.
From Table 2 on page 1, we can see the approximate macromolecule composition of the plants that elephants consume. The majority of their diet consists of water (60 - 80%), followed by carbohydrates (10 - 20%), and lipids (2 - 5%). Proteins are present in relatively small quantities (2 - 5%).
Step 6:: Identify the macromolecule missing from the food that elephants eat.
Based on the information from Tables 1 and 2, it is clear that proteins are nearly absent from the food that elephants consume. Therefore, elephants do not rely on proteins as their primary energy source.
Final Answer
Lions primarily use proteins for energy, while elephants primarily use carbohydrates for energy. This is because the diet of lions consists mainly of herbivores with high protein and lipid content but very low carbohydrate content. In contrast, the diet of elephants consists mainly of plants with high carbohydrate and water content but relatively low protein content.
