Answer:
A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. ... The main components of a habitat are shelter, water, food, and space. A habitat is said to have a suitable arrangement when it has the correct amount of all of these.
Independent Variable: flight
Dependent Variable: size of parachutes
Controlled Variables: precipitation, wind speed, person using parachute (weight), and the shape of the parachute.
The question is slightly broad; it does not specify whether the experiment focuses on the quality of the flight (stability in the air), speed of descent, or the distance it can travel. However, this is what I have come up with.
