Perform online or offline research to learn more about the major diseases that affect crops. Type the name of the disease, its causes (organism, nutritional deficiency, mechanical injury, etc.), its symptoms, and preventive or curative measures for the crops mentioned in the table below.

As the months pass, the table shows that the number of bats also causes an increase in the number of cactus flowers and fruit.

The cactus fruit don't seem to form in large number until the cactus flowers are also going up more in number. This is because pollination is necessary to form the fruit.

Based on this information:

The more bats in the population, the more pollination takes place, and the more cactus fruit is available as a result.

However, if the bats hit carrying capacity, they will be at a population number that is now bad for the number of cactus fruit, since there won't be enough food to feed the population- as more bats eat more fruit, the cactus isn't able to keep up with growing enough fruit to feed the bats at carrying capacity.
