A population estimate is a calculation of the size of a population for a year between census periods or for the current year.
The correct answers are:
B) Predation;
C) Decomposition;
The fungi are found in many different forms, and they practice numerous styles of life. The fungi can be considered as organisms that are decomposing. They are actually the main living organisms that take advantage of the decomposing organisms, but they too find themselves in a situation where they decompose once their life is over. Also, some fungi, around 150 species from what is known so far, are actually predators. They are feeding on nematode worms. They have developed ways to trap the worms, or just simply snag them with an adhesive that sticks to them.
The fungi though can not be considered as autotrophs. The reason for that is that they are not producers, but instead they use the producers as food source, thus making them heterotrophs.
Ozone depletion would cause more UV rays to pass through so your answer would be B)
Pollution causes B)
