Q7. Imagine a hypothetical 5-species community with two primary producers (plants), two herbivores, and one predator. What's the best way to determine which primary producer is competitively dominant

By removing the two herbivores from the community and then estimate the population of each primary producers with time.

Explanation:

The best way to determine which of the primary producer is competitively dominant would be by removing the two herbivores from the community and then study the population of each primary producers with time. A more thriving population in the absence of the predatory herbivores can be deduced to be the dominant species when it comes to competition.

The removal of the herbivores would be necessary because selective predation can favor the thriving of one primary producer over the other and would not be a fair playing ground for competition.

Hence, in the absence of predators, the primary producers would have a fair ground to compete with each other, and with time, a better thriving one can be said to be competitively dominant.

This is non point

Explanation:

Because usually point sources come from a pipe or you can track it down to a certain exact location but you can not track down dog poop from multiple dogs down to one exact location.

Hope this helps
