Ex. Snakes have small leg bones (hips), Human tail bone & appendix.
What is a analogous structures?
Body parts are similar in function but are not similar in basic structure.(shows no evolutionary trend)
Ex. Wings of birds & wings of insects.
What is biology?
Study of life & living organisms. (Including their structure, function, growth, origin, evolution, distribution, & taxonomy.)
What is the practice & science of classification?
What is ecology?
Study of the relation of living organisms with each other & their surroundings.
What is a producer?
Produce energy for themselves from non-living sources through a process known as photosynthesis.

What is an autotroph?
An orgainsm that makes their own food. (producer)
What organism obtains food from other organisms?
What organism breaks down organic matter?
What is nitrogen fixation?
Several species of bacteria have enzymes that convert nitrogen gas into ammonia.
What do animals use nitrogen for?
To make protein/DNA.
