Which function do pygmy rabbits serve in a desert?
OA) eat sagebrush
B) make their own food
C) perform photosynthesis
D) convert light energy to chemical energy

A

Explanation:

A: Eat sagebrush

A rabbit is an animal. It cannot make it's own food. It is a heterotroph, and it needs to feed on other organisms to survive. A pygmy rabbit would eat sagebrush, therefore this is the correct answer.

B: Make their own food

Rabbits and animals can't make their own food, they have to eat other things to survive. Therefore, this answer is incorrect.

C: Perform photosynthesis

Rabbits and animals can't perform photosynthesis, only plants, algae, and certain bacteria can. This answer is also wrong.

D: Convert light energy to chemical energy

In the process of photosynthesis, light energy from the sun is turned into chemical energy. Animals like rabbits can't perform photosynthesis, so this choice is also incorrect.

The best choice is A: eat sagebrush.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
