3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.

Answers

Answer:

Changing temperature causes extinction or removal of organism from that place.

Explanation:

Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.

if the mass extinction event that had wiped out the dinosaurs had not occurred, could dinosaurs rather than mammals have evolved into an intelligent organism resembling modern day humans ?

Answers

Answer:

If the mass extinction even that had wiped out the dinosaurs had not occurred, dinosaurs would've evolved. Though maybe not into organisms that resemble modern-day humans, they would've become better versions of themself. However, some of them might've died out naturally due to climate change and other natural disasters.

If the mass extinction event had wiped out the dinosaurs and not occurred. The dinosaurs would not have been converted into an intelligent organism like humans, because evolution may be bad or good, nothing is always evolution that results in good traits.

What are dinosaurs?

Dinosaurs are extinct reptiles, that were very big, and they were both herbivorous and carnivorous. These animals were present 56 million years ago. They got extinct because of an unknown reason, but scientists say that they got extinct due to the falling of meteorites.

If dinosaurs had not been extinct, they would be evolved according to the changes in the environment. They would not be converted into human intelligence.

Therefore, since evolution can be either positive or negative, there is no guarantee that it will always produce positive features in organisms, the dinosaurs would not have evolved into sophisticated beings like humans.

t=v/a

Explanation:

To solve for Time

Since acceleration is change in velocity/time
