Afood that supplies two grams each of fat, carbohydrate, and protein calories.

34 calories

Explanation:

One gram of carbohydrates provides total= 4 calories.

2 grams of carbohydrates would provide= 4 x 2 = 8 calories.

One gram of protein provides total= 4 calories.

2 grams of protein would provide= 4 x 2 = 8 calories.

One gram of fat provides total= 9 calories.

2 grams of carbohydrates would provide= 9 x 2 = 18 calories.

Total calories from food that gives two grams each of fat, carbohydrate, and protein= 8 + 8 + 18 = 34 calories.  

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
