Answer:
Running into an old friend who is in town for one day.
Explanation:
The term "fortuitous" refers to a chance occurrence, a surprising and unexpected event that happened, a fortunate event. This word is used to talk about things that happened unplanned and completely unexpected.
A fortuitous event means an event that happened so suddenly and unexpectedly that it leaves you shocked and completely unforeseen. Such an event is wholly unexpected and surprising. So,<u> running into an old friend who's in town for a single day is a fortuitous event</u>, for it is a chance encounter and not something that happens often or even planned.
Thus, the correct answer is the last/ fourth option.
Answer:
Biotic factors and abiotic factors work hand to hand to create an ecosystem. Without the soil, plants wouldn't be able to grow and animals wouldn't be able to eat them. Without dead animals the soil wouldn't be able to get enough nutrients to sustain the plants. Biotic factors are animals, plants, fungus, etc. Abiotic factors are the soil, air, water, etc. They combine together by living off of each things they give.
