What type of rock forms when preexisting rocks undergo changes in response to a modification of their environment, without first melting? igneous rocks sedimentary rocks metamorphic rocks meteorites?

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
