Which activity directly converts energy from the sun into chemical energy? a snake lying on a sunny rock to keep warm a rabbit using energy from food it has eaten to run a bean plant making its own food to grow a person burning firewood to cook food

a bean plant making its own food to grow

Explanation:

The plants are the autotrophic organisms which means they are capable of producing their own food by the process of photosynthesis. The use water and carbon dioxide as reactants in the presence of sunlight to produce carbohydrates (food) and oxygen. This way the light energy from sun is converted into chemical energy in the form of food.

On the basis of the above description, a bean plant making its own food to grow is the correct option. As all plants are capable of producing their own food by the process of photosynthesis.    

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
