Answer:
This question is incomplete as the term to match with the level of organisation is not included, the terms are;
circulatory system
cardiac muscle
heart
human body
The ANSWER is:
Organ = heart
Organ system = circulatory system
Tissue: cardiac muscle
Explanation:
The level of organization of multicellular organisms is made up of cell, tissue, organ, organ system and eventually organism.
- The tissue is composed of several cell, which are basic units of any living organism. Cells that perform similar function come together to form the tissue. Example is the CARDIAC MUSCLE in this question, which is a muscular tissue made up of cells called myocardiocytes.
- Organs are structures formed as a result of collection of tissues with similar function. For example, the HEART is a circulatory organ made up of cardiac tissues, connective tissues etc.
- Organ systems is made up of organs that perform the same function in a living organism. In the case of the CIRCULATORY SYSTEM, it is made up of organs such as heart, blood vessels, lungs etc.
