Either B and D I believe I may be wrong..
Answer: Option C - decomposers; they return biotic material to the abiotic component of the Earth
Explanation:
Decomposers are also known as SAPROPHYTES. They feed on and break down dead and decaying remains of plants and animals, thus enabling the release of certain compounds like ammonia, methane gas etc into the environment that then enrich/improve the soil fertility.
It has a lot of advantages as well as disadvantages; but they prevent or suppress the entry of pathogens; colonies produced by some organisms of normal flora have a harmful effect on the pathogens; endotoxins liberated by normal flora may help the defense mechanism of the body.

Which of the following is a plant waste product?
A. oxygen
<u>B. carbon dioxide </u>
C. water
D. sugar
Answer:
B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose.
Explanation:
The following statements that support the conclusion that photosynthesis follows the law of conservation would be B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose. We can conclude this because the law of conservation states that for any transfer of mass, it will always stay the same, meaning that you cannot add to it nor remove from it. Option A would not be correct because the question asked about photosynthesis, and A is describing cellular respiration. Options C and D would also not be correct because when you add up the values in the way that they are listed, it does not sum up to the statement. Here are all of the letter combinations added together, based on the letter choices:
B and C ➡ 372
A and D ➡ 372
A and B ➡ 300
C and D ➡ 444
A and C ➡ 456
B and D ➡ 288
Notice how the first two listed add up to 372. And because this matches option B, that will be your answer.
