The multicellular clade that appeared first in the history of life on Earth is ANIMALIA.

The Kingdom Animalia (also known as Metazoa) is a clade that consists of multicellular-heterotrophic organisms, which cannot synthesize their own food.

It has been estimated that the first animals evolved around 800 million years ago.

The first animals that appeared on the Earth were sponges or sponge-like animals.

In conclusion, the multicellular clade that appeared first in the history of life on Earth is ANIMALIA.

Protista

Explanation:

Protista is the first class of multicellular organism that arose in history. The first of this member is cyanobacteria.

Cyanobacteria is large group of photosynthetic organism that produce their own food by using light energy from sun and carbondioxide.

The first evidence of multicellularity is from cyanobacteria-like organisms that lived 3–3.5 billion years ago.

They help to can convert inert atmospheric nitrogen into an organic form, such as nitrate or ammonia.

The correct answer is A)C02.

Explanation:

The Calvin cycle is a biochemical process that takes place in photosynthesis (more precisely in the stroma of chloroplasts). It is a stage of the same, which does not depend on light, allowing the fixation of CO2, using the enzyme RUBISCO.
