I would say man made but not to sure with out answer choices..
Answer:
This question lacks options, the options are:
1. an ecosystem completely out of balance
2. how ecosystems maintain stability over time
3. interaction between biotic and abiotic factors within an ecosystem
4. ecological succession
The answer is 2
Explanation:
An ecosystem comprises of biotic organisms, abiotic substances etc. that interact with one another. The biotic components of an ecosystem are known to feed on one another in order to obtain energy. However, stability of an ecosystem must be maintained between predators and prey or else there will be extinction of many species of organisms.
One way balance in an ecosystem is maintained over time is by the increase and decrease in population of predators and preys in an ecosystem. For example, If the population of hawks (predator) in an area increases, their prey populations might decrease because there will be less predation.
Also, at a later time, when there is a fewer population of prey, the hawk population might decrease because there is less food to eat. The prey populations might then increase.

i hope this helps! :)
Explanation:
gene flow is a movement of the genes in or out of population. This movement can be caused by the migration of organisms that reproduce in the populations. Or the movements of the gametes

Stonefly larvae, for example, are very sensitive to polluted water and low dissolved oxygen. You collect a lot of stonefly larvae in your study of a local stream and conclude that this stream has high levels of dissolved oxygen and is minimally polluted. Your conclusion is an example of deductive reasoning.
- In both science and daily life, deductive reasoning is a sort of deduction. It occurs when you combine two genuine premises to arrive at a conclusion.
- As an illustration, A = B. B and C are also equal. Deductive reasoning allows you to draw the conclusion that A and C are equal given those two statements.
- Every dolphin is a mammal, Every mammal possesses kidneys.
- You can draw the conclusion that all dolphins have kidneys through deductive reasoning. Keep in mind that for this to function, both assertions must be true.
