Answer:
Correct Answer: A
Solution:
[a] Food chain is a series of organisms interrelated in their feeding habits, the smallest being fed upon by a larger one, which in rum feeds a still larger one, etc.
A food chain begins with a producer, usually a green plant or alga that creates its own food through photosynthesis.
Limitation of the length of the food chain does not depend on one organisms ability to consume another.
