Food on a spoon

colher de sopa is a tablespoon

in cooking terms I would call the first one a heaped/heaping tablespoon, the second would be a tablespoon, the third would be a scant tablespoon

For scant we'd say level in the UK. The ingredient is levelled off to the sides of the spoon.

20g/20ml is a tablespoon / 4 teaspoons
15g/15ml is 3 teaspoons
10g/10ml is 2 teaspoons
