Ineed with this problem asap! and i will give brainliest answer
1. they convert energy from the sun into usable chemical energy by the process of photosynthesis. they are producers primary consumers decomposers
2. as we move up a energy pyramid, the amount of energy available to each level of consumers decreases increases stays the same
3. the main source of energy for almost all food chains is producers the sun the soil

3 is the sun i just took the test and that was the correct answer

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
