A key strategy in sustainable farming is integrated pest management (IPM) which is the combination of different techniques to cr

eate an effective pest control system. Not all pests need to be eliminated; monitoring and prevention of pest is also an integral part of IPM. Aquafarming is the farming of aquatic species such as fish, crustaceans, mollusks, and aquatic plants and often uses sustainable farming techniques. The limits of a certain type of aquafarming pest during the farming of catfish might be expressed as a 10 ug/L, not to exceed 2 days, and not to recur more than once every 6 months. What does 6 months represent in the management of pest limits for the above example?
a) average
b) duration
c) frequency
d) magnitude

Answer:

The correct answer is C. Frequency.

Explanation:

In statistics, frequency is called the period of time that elapses between a certain event developing and repeating itself again. That is, the frequency measures the duration of the process of repetition of a certain event.

Thus, for example, if an earthquake occurs exactly every 4 months in a certain place, this natural catastrophe occurs with a frequency of 4 months.

Therefore, if the limits of a certain type of aquafarming pest during the farming of catfish might not to recur more than once every 6 months, this expression refers to the frequency with which said event must (or in this case, not must) happen.

How can invasive species alter an ecosystems food web?
Harlamova29_29 [7]

Invasive species can either replace an organism from the ecosystem food web or replace it.  

Explanation:

  • Invasive species are non-native species which can be animals, plants, micro-organisms, fish, etc. they are very much threatening to the native species and ecosystem food web.
  • Invasive species are spread by humans mostly, it happens unintentionally when people travel and all. Even climate change could be a reason for its spread.
  • So, it becomes threatening to native species because when you introduce it into a new ecosystem, it does not have a predator or control. It grows aggressively and takes over the resources for the native species.

DerKrebs [107]

Answer:

Some examples of decomposers include bacteria, fungi, and some insects. If decomposers disappeared from a forest ecosystem, wastes as well as the remains of the dead organisms would pile up, and producers (plants) would not have enough nutrients.
