Anna tries to keep her kilocalorie intake under control. She eats mostly lean meats or fish and a lot of vegetables. Yesterday, for dinner, she had 3 ounces of baked salmon with half a cup of mashed sweet potatoes and about a cup of steamed asparagus. She is concerned about her weight and decided to calculate the kilocalories in her meal. She looked up the nutrient content of her foods and she consumed
7 grams of fat (in salmon)
36 grams of carbohydrates (in sweet potatoes and asparagus)
27 grams of protein (in salmon, sweet potatoes, and asparagus)
(A) How many kilocalories did Anna consume for dinner? Round the number of kilocalories to the nearest whole number.
(B) How many of Anna's kilocalories came from proteins? Round the number of kilocalories to the nearest whole number.

The calories Anna consumed for dinner is 315 kcal (300kcal). The calories that came from proteins is 108 kcal (100kcal).

Explanation:

Macronutrients are nutrients such as protein, carbohydrates, and fat that provide the energy required for the normal functioning of the body. Usually, the energy obtained from macronutrients is expressed in calories. Each gram of protein provides 4 kilocalories while each gram of fat provides 9 kilocalories. Carbohydrates per gram also provide 4 kilocalories.

Here, Anna consumed  7 grams of fat (in salmon)

, 36 grams of carbohydrates (in sweet potatoes and asparagus)  and 27 grams of protein (in salmon, sweet potatoes, and asparagus) for the dinner.

Therefore, total calories in 7 grams of fat is kilocalories.

Total calories in 36 grams of carbohydrates is kilocalories.

Total calories in 27 grams of protein is kilocalories.

Therefore, the total calories Anna consumed for dinner is kilocalories i.e., kcal.

The calories that came from proteins is calories  i.e., kcal.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

there's the proffessional site that will you.
