Answer:
Tissue
Explanation:
Multicellular organisms are complex and every complex organism consist of building blocks. This is the case in the level of organization in living organisms. All living organisms are made up of CELLS. In multicellular organisms i.e. more than one, the cells that perform a similar role come together to form the TISSUE.
Tissues with similar function together forms the ORGAN. Organs that perform similar functions collectively makes up ORGAN SYSTEM. Based on this, the level of organization moves from the least complex "cells" to most complex "organ systems".
The order is as follows:
Cell-----> Tissue-----> Organ-----> Organ systems
Answer:
The tree is the autotroph.
Explanation:
<u>First, let's define what autotrophs are.</u>
Autotrophs are organisms that make their own food, not relying on other organisms to eat.
<u>Now let's explain why trees are the answer.</u>
Trees use photosynthesis to make their own foods in the form of glucose (or sugar). The plant then uses these to sustain themselves. This process makes them an autotroph.
