Sorry, as a teacher I'm opposed to giving you answers to homework questions because that's called helping you cheat.
I will however help you figure out the answer. Question 1 is a logic question. don't read to much into it. if you still have problems figuring out what a first and 2nd level consumer is draw the action of a kestrel eating a mouse that's eating grass.
After reading further I realize that all of these questions and answers are found in any basic Physics textbook. Actually, this seems like a take home test. I'm sorry but its against my ethics to go any further.
In future, please provide your answers and then we can tell you if you're right or on the wrong path.
