Why is 2 the correct i’m horrible at science. !

Given that ATP is the product of the reaction, it must be cellular respiration (also, since it occurs in both plants and animals it can't be photosynthesis).

A and B must be glucose and oxygen. It makes sense if you think about it. We breathe in oxygen, and we eat food. Food contains glucose (sugar). We need to consume these things in order to make energy. Carbon dioxide is D because it's the "left over" of this reaction. That's why we exhale it. And C is enzymes because they catalyze (promote) just about every reaction in the body.

Another way to remember this in the future is just to memorize the equation (attached). Just remember that its the exact opposite of photosynthesis.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
