Lamarck's hypothesis of evolution was based on the theory of acquired inheritance.
---- *Well, since there is really no specific ecosystem that was asked about in the question, I will just list some common and basic abiotic factors found throughout most ecosystems (maybe you can match this with the ecosystem you are talking about).
---------------------------------------------------------------------------------------------------------
Abiotic factors: nonliving parts of an ecosystem
Some abiotic factors include: ROCKS, SOIL, AIR, SUN, WATER, ETC.
The diseases which can be passes down as genetic traits are known as "Inheritable disease" some examples are:
1) Haemophilia
2) Phenylketonuria
3) Down's Syndrome
4) Turner's Syndrome
5) Klinefelter's Syndrome
Hope this helps!
