everyone _____________ each other. A relationship just means a close
_____________________.
b) The 3 types of relationships are ________________________,
__________________________, and ______________________________.
c) When 2 organisms work together to help each other, we call this interaction
____________________________; an example is when __________________
____________________________________________________________.
d) On the other hand, some organisms take advantage of others; one organism is helped
and the host is harmed; this type of interaction is called parasitism and an
______________________ is when leeches absorb nutrients from the host and the
host has lost more blood than it would have.
e) Lastly, we have a relationship where one organism is helped and nothing happens to the

________________.

____________________________________________________________;
