I believe it’s the y variable.
Seed coat-ovary wall association is not correct.
The seed coat originates from the maternal tissue, that is, the integuments. It is one of the three components of a plant seed, in supplementation to the embryo and the endosperm. The aim of the seed coat is to safeguard the seed from temperature-related, physical or water destruction. It is a protective outer covering of the seed.
On the other hand, the ovary wall refers to the wall of the ovary of a flower that ultimately develops into a pericarp or fruit wall.
Role of decomposer in fooe chain/food web
Decomposers are organisms which convert complex organic molecules into their simple forms.
Example
bacteria, fungi etc.
Explanation
food chain stary from autotrophs and end at decomposers. these organisms are present in soil, rely on dead bodies of plants and animals for their nutrient requirements. These organisms possess strong enzymatic system, which scavenge comples molecules from dead bodies during respiration and convert them into simple nutrients which return back to atmosphere.
These characteristics are examples of emergent properties.
I think it might be the third option but I’m not sure
