An extinction event is a well-known
and quick decrease in the biodiversity on Earth. Such an occurrence
is recognized by a sharp change in the diversity and abundance of multicellular organisms. It happens when the
rate of extinction surges with respect to the rate of speciation.
In other words, this happens when species cannot adapt generally to the change
in the environment. So the correct answer would be letter a.
Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product.
