Why did many plants die at the end of the mesozoic era?

Dust from the meteorite collision obstructed sunlight is the right answer.

Based on the general argument that the dinosaurs went obsolete due to the result of a massive asteroid, experts consider that the asteroid produced large amounts of trash to float into the environment, obstructing the path of the sun. This resulted in global temperature decline which caused the plants to freeze. Moreover, the process of photosynthesis could not be carried out in the absence of the sun. Therefore, the absence of the sun at the end of the Mesozoic age caused the death of plants.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

the correct answer is option d.

an appositive is a noun, noun phrase or noun clause which follows another noun or noun phrase in order to describe it or name it another way. they are usually used between commas, brackets or dashes.
